--ensure-on-bed Lift the object above the bed when it is partially below. Enabled by default,
use --no-ensure-on-bed to disable.
--merge, -m Arrange the supplied models in a plate and merge them in a single model in order
to perform actions once.
--repair Try to repair any non-manifold meshes (this option is implicitly added whenever
we need to slice the model to perform the requested action).
--rotate N Rotation angle around the Z axis in degrees.
--rotate-x N Rotation angle around the X axis in degrees.
--rotate-y N Rotation angle around the Y axis in degrees.
--scale N Scaling factor or percentage.
--scale-to-fit X,Y,Z
Scale to fit the given volume.
--split Detect unconnected parts in the given model(s) and split them into separate
objects.
Other options:
--config-compatibility
This version of PrusaSlicer may not understand configurations produced by the
newest PrusaSlicer versions. For example, newer PrusaSlicer may extend the list
of supported firmware flavors. One may decide to bail out or to substitute an
unknown value with a default silently or verbosely. (disable, enable,
enable_silent; default: enable)
--datadir ABCD Load and store settings at the given directory. This is useful for maintaining
different profiles or including configurations from a network storage.
--ignore-nonexistent-config
Do not fail if a file supplied to --load does not exist.
--load ABCD Load configuration from the specified file. It can be used more than once to
load options from multiple files.
--loglevel N Sets logging sensitivity. 0:fatal, 1:error, 2:warning, 3:info, 4:debug, 5:trace
For example. loglevel=2 logs fatal, error and warning level messages.
--output ABCD, -o ABCD
The file where the output will be written (if not specified, it will be based on
the input file).
--single-instance If enabled, the command line arguments are sent to an existing instance of GUI
PrusaSlicer, or an existing PrusaSlicer window is activated. Overrides the
"single_instance" configuration value from application preferences.
Print options are processed in the following order:
1) Config keys from the command line, for example --fill-pattern=stars
(highest priority, overwrites everything below)
2) Config files loaded with --load
3) Config values loaded from amf or 3mf files
Misc options:
--avoid-crossing-perimeters
Optimize travel moves in order to minimize the crossing of perimeters. This is
mostly useful with Bowden extruders which suffer from oozing. This feature slows
down both the print and the G-code generation.
--bed-custom-model ABCD
--bed-custom-texture ABCD
--bed-shape (default: 0x0,200x0,200x200,0x200)
--bed-temperature N Bed temperature for layers after the first one. Set this to zero to disable bed
temperature control commands in the output. (°C, default: 0)
--before-layer-gcode ABCD
This custom code is inserted at every layer change, right before the Z move.
Note that you can use placeholder variables for all Slic3r settings as well as
[layer_num] and [layer_z].
--between-objects-gcode ABCD
This code is inserted between objects when using sequential printing. By default
extruder and bed temperature are reset using non-wait command; however if M104,
M109, M140 or M190 are detected in this custom code, Slic3r will not add
temperature commands. Note that you can use placeholder variables for all Slic3r
settings, so you can put a "M109 S[first_layer_temperature]" command wherever
you want.
--bridge-acceleration N
This is the acceleration your printer will use for bridges. Set zero to disable
acceleration control for bridges. (mm/s², default: 0)
--bridge-fan-speed N
This fan speed is enforced during all bridges and overhangs. (%, default: 100)
--clip-multipart-objects
When printing multi-material objects, this settings will make Slic3r to clip the
overlapping object parts one by the other (2nd part will be clipped by the 1st,
3rd part will be clipped by the 1st and 2nd etc).
--color-change-gcode ABCD
This G-code will be used as a code for the color change (default: M600)
--colorprint-heights N
Heights at which a filament change is to occur. (default: )
--complete-objects When printing multiple objects or copies, this feature will complete each object
before moving onto next one (and starting it from its bottom layer). This
feature is useful to avoid the risk of ruined prints. Slic3r should warn and
prevent you from extruder collisions, but beware.
--cooling This flag enables the automatic cooling logic that adjusts print speed and fan
speed according to layer printing time. (default: 1)
--cooling-tube-length N
Length of the cooling tube to limit space for cooling moves inside it. (mm,
default: 5)
--cooling-tube-retraction N
Distance of the center-point of the cooling tube from the extruder tip. (mm,
default: 91.5)
--default-acceleration N
This is the acceleration your printer will be reset to after the role-specific
acceleration values are used (perimeter/infill). Set zero to prevent resetting
acceleration at all. (mm/s², default: 0)
--deretract-speed N The speed for loading of a filament into extruder after retraction (it only
applies to the extruder motor). If left to zero, the retraction speed is used.
(mm/s, default: 0)
--disable-fan-first-layers N
You can set this to a positive value to disable fan at all during the first
layers, so that it does not make adhesion worse. (layers, default: 3)
--draft-shield With draft shield active, the skirt will be printed skirt_distance from the
object, possibly intersecting brim. Enabled = skirt is as tall as the highest
printed object. Limited = skirt is as tall as specified by skirt_height. This is
useful to protect an ABS or ASA print from warping and detaching from print bed
due to wind draft. (disabled, limited, enabled; default: disabled)
--duplicate-distance N
Distance used for the auto-arrange feature of the plater. (mm, default: 6)
--end-filament-gcode ABCD
This end procedure is inserted at the end of the output file, before the printer
end gcode (and before any toolchange from this filament in case of multimaterial
printers). Note that you can use placeholder variables for all PrusaSlicer
settings. If you have multiple extruders, the gcode is processed in extruder
order. (default: "; Filament-specific end gcode \n;END gcode for filament\n")
--end-gcode ABCD This end procedure is inserted at the end of the output file. Note that you can
use placeholder variables for all PrusaSlicer settings. (default: M104 S0 ; turn
off temperature\nG28 X0 ; home X axis\nM84 ; disable motors\n)
--extra-loading-move N
When set to zero, the distance the filament is moved from parking position
during load is exactly the same as it was moved back during unload. When
positive, it is loaded further, if negative, the loading move is shorter than
unloading. (mm, default: -2)
--extruder-clearance-height N
Set this to the vertical distance between your nozzle tip and (usually) the X
carriage rods. In other words, this is the height of the clearance cylinder
around your extruder, and it represents the maximum depth the extruder can peek
before colliding with other printed objects. (mm, default: 20)
--extruder-clearance-radius N
Set this to the clearance radius around your extruder. If the extruder is not
centered, choose the largest value for safety. This setting is used to check for
collisions and to display the graphical preview in the plater. (mm, default: 20)
--extruder-colour ABCD
This is only used in the Slic3r interface as a visual help. (default: "")
--extruder-offset If your firmware doesn't handle the extruder displacement you need the G-code to
take it into account. This option lets you specify the displacement of each
extruder with respect to the first one. It expects positive coordinates (they
will be subtracted from the XY coordinate). (mm, default: 0x0)
--extrusion-axis ABCD
Use this option to set the axis letter associated to your printer's extruder
(usually E but some printers use A). (default: E)
--extrusion-multiplier N
This factor changes the amount of flow proportionally. You may need to tweak
this setting to get nice surface finish and correct single wall widths. Usual
values are between 0.9 and 1.1. If you think you need to change this more, check
filament diameter and your firmware E steps. (default: 1)
--fan-always-on If this is enabled, fan will never be disabled and will be kept running at least
at its minimum speed. Useful for PLA, harmful for ABS. (default: 0)
--fan-below-layer-time N
If layer print time is estimated below this number of seconds, fan will be
enabled and its speed will be calculated by interpolating the minimum and
maximum speeds. (approximate seconds, default: 60)
--filament-colour ABCD
This is only used in the Slic3r interface as a visual help. (default: #29B2B2)

length to volume. Better is to calculate the volume directly through
displacement. (g/cm³, default: 0)
--filament-deretract-speed N
The speed for loading of a filament into extruder after retraction (it only
applies to the extruder motor). If left to zero, the retraction speed is used.
(mm/s, default: 0)

and do multiple measurements along the filament, then compute the average. (mm,
default: 1.75)
--filament-load-time N
Time for the printer firmware (or the Multi Material Unit 2.0) to load a new
filament during a tool change (when executing the T code). This time is added to
the total print time by the G-code time estimator. (s, default: 0)
--filament-loading-speed N
Speed used for loading the filament on the wipe tower. (mm/s, default: 28)
--filament-loading-speed-start N
Speed used at the very beginning of loading phase. (mm/s, default: 3)
--filament-max-volumetric-speed N
Maximum volumetric speed allowed for this filament. Limits the maximum
volumetric speed of a print to the minimum of print and filament volumetric
speed. Set to zero for no limit. (mm³/s, default: 0)
--filament-minimal-purge-on-wipe-tower N
After a tool change, the exact position of the newly loaded filament inside the
nozzle may not be known, and the filament pressure is likely not yet stable.
Before purging the print head into an infill or a sacrificial object, Slic3r
will always prime this amount of material into the wipe tower to produce
successive infill or sacrificial object extrusions reliably. (mm³, default: 15)
--filament-notes ABCD
You can put your notes regarding the filament here. (default: "")
--filament-ramming-parameters ABCD
This string is edited by RammingDialog and contains ramming specific parameters.
(default: "120 100 6.6 6.8 7.2 7.6 7.9 8.2 8.7 9.4 9.9 10.0| 0.05 6.6 0.45 6.8

--filament-retract-length N
When retraction is triggered, filament is pulled back by the specified amount
(the length is measured on raw filament, before it enters the extruder). (mm
(zero to disable), default: 2)
--filament-retract-lift N
If you set this to a positive value, Z is quickly raised every time a retraction
is triggered. When using multiple extruders, only the setting for the first
extruder will be considered. (mm, default: 0)
--filament-retract-lift-above N
If you set this to a positive value, Z lift will only take place above the
specified absolute Z. You can tune this setting for skipping lift on the first
layers. (mm, default: 0)
--filament-retract-lift-below N
If you set this to a positive value, Z lift will only take place below the
specified absolute Z. You can tune this setting for limiting lift to the first
layers. (mm, default: 0)

The speed for retractions (it only applies to the extruder motor). (mm/s,
default: 40)
--filament-soluble Soluble material is most likely used for a soluble support. (default: 0)
--filament-spool-weight N
Enter weight of the empty filament spool. One may weigh a partially consumed
filament spool before printing and one may compare the measured weight with the
calculated weight of the filament with the spool to find out whether the amount
of filament on the spool is sufficient to finish the print. (g, default: 0)
--filament-toolchange-delay N
Time to wait after the filament is unloaded. May help to get reliable
toolchanges with flexible materials that may need more time to shrink to
original dimensions. (s, default: 0)

HIPS, EDGE, NGEN, PA, NYLON, PVA, PC, PP, PEI, PEEK, PEKK, POM, PSU, PVDF,
SCAFF; default: PLA)
--filament-unload-time N
Time for the printer firmware (or the Multi Material Unit 2.0) to unload a
filament during a tool change (when executing the T code). This time is added to
the total print time by the G-code time estimator. (s, default: 0)
--filament-unloading-speed N
Speed used for unloading the filament on the wipe tower (does not affect initial
part of unloading just after ramming). (mm/s, default: 90)
--filament-unloading-speed-start N
Speed used for unloading the tip of the filament immediately after ramming.
(mm/s, default: 100)
--filament-wipe This flag will move the nozzle while retracting to minimize the possible blob on
leaky extruders. (default: 0)
--first-layer-acceleration N
This is the acceleration your printer will use for first layer. Set zero to
disable acceleration control for first layer. (mm/s², default: 0)

Heated build plate temperature for the first layer. Set this to zero to disable
bed temperature control commands in the output. (°C, default: 0)
--first-layer-speed N
If expressed as absolute value in mm/s, this speed will be applied to all the
print moves of the first layer, regardless of their type. If expressed as a
percentage (for example: 40%) it will scale the default speeds. (mm/s or %,
default: 30)
--first-layer-speed-over-raft N
If expressed as absolute value in mm/s, this speed will be applied to all the
print moves of the first object layer above raft interface, regardless of their
type. If expressed as a percentage (for example: 40%) it will scale the default
speeds. (mm/s or %, default: 30)
--first-layer-temperature N
Nozzle temperature for the first layer. If you want to control temperature
manually during print, set this to zero to disable temperature control commands
in the output G-code. (°C, default: 200)
--full-fan-speed-layer N
Fan speed will be ramped up linearly from zero at layer
"disable_fan_first_layers" to maximum at layer "full_fan_speed_layer".
"full_fan_speed_layer" will be ignored if lower than "disable_fan_first_layers",
in which case the fan will be running at maximum allowed speed at layer
"disable_fan_first_layers" + 1. (default: 0)
--gcode-comments Enable this to get a commented G-code file, with each line explained by a
descriptive text. If you print from SD card, the additional weight of the file
could make your firmware slow down.
--gcode-flavor Some G/M-code commands, including temperature control and others, are not
universal. Set this option to your printer's firmware to get a compatible
output. The "No extrusion" flavor prevents PrusaSlicer from exporting any
extrusion value at all. (reprap, reprapfirmware, repetier, teacup, makerware,
marlin, marlin2, sailfish, mach3, machinekit, smoothie, no-extrusion; default:
reprap)
--gcode-label-objects
Enable this to add comments into the G-Code labeling print moves with what
object they belong to, which is useful for the Octoprint CancelObject plugin.
This settings is NOT compatible with Single Extruder Multi Material setup and
Wipe into Object / Wipe into Infill.
--gcode-resolution N
Maximum deviation of exported G-code paths from their full resolution
counterparts. Very high resolution G-code requires huge amount of RAM to slice
and preview, also a 3D printer may stutter not being able to process a high
resolution G-code in a timely manner. On the other hand, a low resolution G-code
will produce a low poly effect and because the G-code reduction is performed at
each layer independently, visible artifacts may be produced. (mm, default:
0.0125)
--gcode-substitutions ABCD
Find / replace patterns in G-code lines and substitute them. (default: )
--high-current-on-filament-swap
It may be beneficial to increase the extruder motor current during the filament
exchange sequence to allow for rapid ramming feed rates and to overcome
resistance when loading a filament with an ugly shaped tip.
--infill-acceleration N
This is the acceleration your printer will use for infill. Set zero to disable
acceleration control for infill. (mm/s², default: 0)
--infill-first This option will switch the print order of perimeters and infill, making the
latter first.
--after-layer-gcode ABCD, --layer-gcode ABCD
This custom code is inserted at every layer change, right after the Z move and
before the extruder moves to the first layer point. Note that you can use
placeholder variables for all Slic3r settings as well as [layer_num] and
[layer_z].
--max-fan-speed N This setting represents the maximum speed of your fan. (%, default: 100)
--max-layer-height N
This is the highest printable layer height for this extruder, used to cap the
variable layer height and support layer height. Maximum recommended layer height
is 75% of the extrusion width to achieve reasonable inter-layer adhesion. If set
to 0, layer height is limited to 75% of the nozzle diameter. (mm, default: 0)
--max-print-height N
Set this to the maximum height that can be reached by your extruder while
printing. (mm, default: 200)
--max-print-speed N When setting other speed settings to 0 Slic3r will autocalculate the optimal
speed in order to keep constant extruder pressure. This experimental setting is
used to set the highest print speed you want to allow. (mm/s, default: 80)
--max-volumetric-extrusion-rate-slope-negative N
This experimental setting is used to limit the speed of change in extrusion rate
for a transition from higher speed to lower speed. A value of 1.8 mm³/s²
ensures, that a change from the extrusion rate of 5.4 mm³/s (0.45 mm extrusion
width, 0.2 mm extrusion height, feedrate 60 mm/s) to 1.8 mm³/s (feedrate 20
mm/s) will take at least 2 seconds. (mm³/s², default: 0)
--max-volumetric-extrusion-rate-slope-positive N
This experimental setting is used to limit the speed of change in extrusion rate
for a transition from lower speed to higher speed. A value of 1.8 mm³/s²
ensures, that a change from the extrusion rate of 1.8 mm³/s (0.45 mm extrusion
width, 0.2 mm extrusion height, feedrate 20 mm/s) to 5.4 mm³/s (feedrate 60
mm/s) will take at least 2 seconds. (mm³/s², default: 0)
--max-volumetric-speed N
This experimental setting is used to set the maximum volumetric speed your
extruder supports. (mm³/s, default: 0)
--min-fan-speed N This setting represents the minimum PWM your fan needs to work. (%, default: 35)
--min-layer-height N
This is the lowest printable layer height for this extruder and limits the
resolution for variable layer height. Typical values are between 0.05 mm and 0.1
mm. (mm, default: 0.07)
--min-print-speed N Slic3r will not scale speed down below this speed. (mm/s, default: 10)
--min-skirt-length N
Generate no less than the number of skirt loops required to consume the
specified amount of filament on the bottom layer. For multi-extruder machines,
this minimum applies to each extruder. (mm, default: 0)
--notes ABCD You can put here your personal notes. This text will be added to the G-code
header comments.
--nozzle-diameter N This is the diameter of your extruder nozzle (for example: 0.5, 0.35 etc.) (mm,
default: 0.4)
--only-retract-when-crossing-perimeters
Disables retraction when the travel path does not exceed the upper layer's
perimeters (and thus any ooze will be probably invisible).
--ooze-prevention This option will drop the temperature of the inactive extruders to prevent
oozing. It will enable a tall skirt automatically and move extruders outside
such skirt when changing temperatures.
--output-filename-format ABCD
You can use all configuration options as variables inside this template. For
example: [layer_height], [fill_density] etc. You can also use [timestamp],
[year], [month], [day], [hour], [minute], [second], [version], [input_filename],
[input_filename_base]. (default: [input_filename_base].gcode)
--parking-pos-retraction N
Distance of the extruder tip from the position where the filament is parked when
unloaded. This should match the value in printer firmware. (mm, default: 92)
--pause-print-gcode ABCD
This G-code will be used as a code for the pause print (default: M601)
--perimeter-acceleration N
This is the acceleration your printer will use for perimeters. Set zero to
disable acceleration control for perimeters. (mm/s², default: 0)
--post-process ABCD If you want to process the output G-code through custom scripts, just list their
absolute paths here. Separate multiple scripts with a semicolon. Scripts will be
passed the absolute path to the G-code file as the first argument, and they can
access the Slic3r config settings by reading environment variables. (default: )
--preset-name ABCD
--preset-names ABCD Names of presets related to the physical printer (default: )
--printer-notes ABCD
You can put your notes regarding the printer here.
--printer-technology
Printer technology (FFF, SLA; default: FFF)
--remaining-times Emit M73 P[percent printed] R[remaining time in minutes] at 1 minute intervals
into the G-code to let the firmware show accurate remaining time. As of now only
the Prusa i3 MK3 firmware recognizes M73. Also the i3 MK3 firmware supports M73
Qxx Sxx for the silent mode.
--resolution N Minimum detail resolution, used to simplify the input file for speeding up the
slicing job and reducing memory usage. High-resolution models often carry more
detail than printers can render. Set to zero to disable any simplification and
use full resolution from input. (mm, default: 0)
--retract-before-travel N
Retraction is not triggered when travel moves are shorter than this length. (mm,
default: 2)
--retract-before-wipe
With bowden extruders, it may be wise to do some amount of quick retract before
doing the wipe movement. (%, default: 0%)
--retract-layer-change
This flag enforces a retraction whenever a Z move is done. (default: 0)
--retract-length N When retraction is triggered, filament is pulled back by the specified amount
(the length is measured on raw filament, before it enters the extruder). (mm
(zero to disable), default: 2)
--retract-length-toolchange N
When retraction is triggered before changing tool, filament is pulled back by
the specified amount (the length is measured on raw filament, before it enters
the extruder). (mm (zero to disable), default: 10)
--retract-lift N If you set this to a positive value, Z is quickly raised every time a retraction
is triggered. When using multiple extruders, only the setting for the first
extruder will be considered. (mm, default: 0)
--retract-lift-above N
If you set this to a positive value, Z lift will only take place above the
specified absolute Z. You can tune this setting for skipping lift on the first
layers. (mm, default: 0)
--retract-lift-below N
If you set this to a positive value, Z lift will only take place below the
specified absolute Z. You can tune this setting for limiting lift to the first
layers. (mm, default: 0)
--retract-restart-extra N
When the retraction is compensated after the travel move, the extruder will push
this additional amount of filament. This setting is rarely needed. (mm, default:
0)
--retract-restart-extra-toolchange N
When the retraction is compensated after changing tool, the extruder will push
this additional amount of filament. (mm, default: 0)
--retract-speed N The speed for retractions (it only applies to the extruder motor). (mm/s,
default: 40)

If enabled, all printing extruders will be primed at the front edge of the print
bed at the start of the print.
--skirt-distance N Distance between skirt and brim (when draft shield is not used) or objects. (mm,
default: 6)
--skirt-height N Height of skirt expressed in layers. (layers, default: 1)
--skirts N Number of loops for the skirt. If the Minimum Extrusion Length option is set,
the number of loops might be greater than the one configured here. Set this to
zero to disable skirt completely. (default: 1)
--slowdown-below-layer-time N
If layer print time is estimated below this number of seconds, print moves speed
will be scaled down to extend duration to this value. (approximate seconds,
default: 5)
--solid-layers N Number of solid layers to generate on top and bottom surfaces.
--solid-min-thickness N
Minimum thickness of a top / bottom shell
--spiral-vase This feature will raise Z gradually while printing a single-walled object in
order to remove any visible seam. This option requires a single perimeter, no
infill, no top solid layers and no support material. You can still set any
number of bottom solid layers as well as skirt/brim loops. It won't work when
printing more than one single object.
--standby-temperature-delta N
Temperature difference to be applied when an extruder is not active. Enables a
full-height "sacrificial" skirt on which the nozzles are periodically wiped.
(∆°C, default: -5)
--start-filament-gcode ABCD
This start procedure is inserted at the beginning, after any printer start gcode
(and after any toolchange to this filament in case of multi-material printers).
This is used to override settings for a specific filament. If PrusaSlicer
detects M104, M109, M140 or M190 in your custom codes, such commands will not be
prepended automatically so you're free to customize the order of heating
commands and other custom actions. Note that you can use placeholder variables
for all PrusaSlicer settings, so you can put a "M109 S[first_layer_temperature]"
command wherever you want. If you have multiple extruders, the gcode is
processed in extruder order. (default: "; Filament gcode\n")
--start-gcode ABCD This start procedure is inserted at the beginning, after bed has reached the
target temperature and extruder just started heating, and before extruder has
finished heating. If PrusaSlicer detects M104 or M190 in your custom codes, such
commands will not be prepended automatically so you're free to customize the
order of heating commands and other custom actions. Note that you can use
placeholder variables for all PrusaSlicer settings, so you can put a "M109
S[first_layer_temperature]" command wherever you want. (default: G28 ; home all
axes\nG1 Z5 F5000 ; lift nozzle\n)
--temperature N Nozzle temperature for layers after the first one. Set this to zero to disable
temperature control commands in the output G-code. (°C, default: 200)
--template-custom-gcode ABCD
This G-code will be used as a custom code
--thumbnails Picture sizes to be stored into a .gcode and .sl1 / .sl1s files, in the
following format: "XxY, XxY, ..." (default: )
--thumbnails-format Format of G-code thumbnails: PNG for best quality, JPG for smallest size, QOI
for low memory firmware (PNG, JPG, QOI; default: PNG)
--toolchange-gcode ABCD
This custom code is inserted before every toolchange. Placeholder variables for
all PrusaSlicer settings as well as {toolchange_z}, {previous_extruder} and
{next_extruder} can be used. When a tool-changing command which changes to the
correct extruder is included (such as T{next_extruder}), PrusaSlicer will emit
no other such command. It is therefore possible to script custom behaviour both
before and after the toolchange.
--travel-speed N Speed for travel moves (jumps between distant extrusion points). (mm/s, default:
130)
--travel-speed-z N Speed for movements along the Z axis. When set to zero, the value is ignored and
regular travel speed is used instead. (mm/s, default: 0)
--use-firmware-retraction
This experimental setting uses G10 and G11 commands to have the firmware handle
the retraction. This is only supported in recent Marlin.
--use-relative-e-distances
If your firmware requires relative E values, check this, otherwise leave it
unchecked. Most firmwares use absolute values.
--use-volumetric-e This experimental setting uses outputs the E values in cubic millimeters instead
of linear millimeters. If your firmware doesn't already know filament
diameter(s), you can put commands like 'M200 D[filament_diameter_0] T0' in your
start G-code in order to turn volumetric mode on and use the filament diameter
associated to the filament selected in Slic3r. This is only supported in recent
Marlin.
--variable-layer-height
Some printers or printer setups may have difficulties printing with a variable
layer height. Enabled by default.
--wipe This flag will move the nozzle while retracting to minimize the possible blob on
leaky extruders. (default: 0)
--wipe-tower Multi material printers may need to prime or purge extruders on tool changes.
Extrude the excess material into the wipe tower.
--wipe-tower-bridging N
Maximal distance between supports on sparse infill sections. (mm, default: 10)
--wipe-tower-brim-width N
Wipe tower brim width (mm, default: 2)
--wipe-tower-no-sparse-layers
If enabled, the wipe tower will not be printed on layers with no toolchanges. On
layers with a toolchange, extruder will travel downward to print the wipe tower.
User is responsible for ensuring there is no collision with the print.
--wipe-tower-rotation-angle N
Wipe tower rotation angle with respect to x-axis. (°, default: 0)
--wipe-tower-width N
Width of a wipe tower (mm, default: 60)
--wipe-tower-x N X coordinate of the left front corner of a wipe tower (mm, default: 180)
--wipe-tower-y N Y coordinate of the left front corner of a wipe tower (mm, default: 140)
--wiping-volumes-extruders N
This vector saves required volumes to change from/to each tool used on the wipe
tower. These values are used to simplify creation of the full purging volumes
below. (default: 70,70,70,70,70,70,70,70,70,70)
--wiping-volumes-matrix N
This matrix describes volumes (in cubic milimetres) required to purge the new
filament on the wipe tower for any given pair of tools. (default:
0,140,140,140,140,140,0,140,140,140,140,140,0,140,140,140,140,140,0,140,140,140,140,140,0)
--z-offset N This value will be added (or subtracted) from all the Z coordinates in the
output G-code. It is used to compensate for bad Z endstop position: for example,
if your endstop zero actually leaves the nozzle 0.3mm far from the print bed,
set this to -0.3 (or fix your endstop). (mm, default: 0)
Advanced:
--bridge-flow-ratio N
This factor affects the amount of plastic for bridging. You can decrease it
slightly to pull the extrudates and prevent sagging, although default settings
are usually good and you should experiment with cooling (use a fan) before
tweaking this. (default: 1)
--elefant-foot-compensation N
The first layer will be shrunk in the XY plane by the configured value to
compensate for the 1st layer squish aka an Elephant Foot effect. (mm, default:
0)
--infill-anchor N Connect an infill line to an internal perimeter with a short segment of an
additional perimeter. If expressed as percentage (example: 15%) it is calculated
over infill extrusion width. PrusaSlicer tries to connect two close infill lines
to a short perimeter segment. If no such perimeter segment shorter than
infill_anchor_max is found, the infill line is connected to a perimeter segment
at just one side and the length of the perimeter segment taken is limited to
this parameter, but no longer than anchor_length_max. Set this parameter to zero
to disable anchoring perimeters connected to a single infill line. (mm or %,
default: 600%)
--infill-anchor-max N
Connect an infill line to an internal perimeter with a short segment of an
additional perimeter. If expressed as percentage (example: 15%) it is calculated
over infill extrusion width. PrusaSlicer tries to connect two close infill lines
to a short perimeter segment. If no such perimeter segment shorter than this
parameter is found, the infill line is connected to a perimeter segment at just
one side and the length of the perimeter segment taken is limited to
infill_anchor, but no longer than this parameter. Set this parameter to zero to
disable anchoring. (mm or %, default: 50)
--infill-overlap N This setting applies an additional overlap between infill and perimeters for
better bonding. Theoretically this shouldn't be needed, but backlash might cause
gaps. If expressed as percentage (example: 15%) it is calculated over perimeter
extrusion width. (mm or %, default: 25%)
--min-bead-width N Width of the perimeter that will replace thin features (according to the Minimum
feature size) of the model. If the Minimum perimeter width is thinner than the
thickness of the feature, the perimeter will become as thick as the feature
itself. If expressed as a percentage (for example 85%), it will be computed
based on the nozzle diameter. (mm or %, default: 85%)
--min-feature-size N
Minimum thickness of thin features. Model features that are thinner than this
value will not be printed, while features thicker than the Minimum feature size
will be widened to the Minimum perimeter width. If expressed as a percentage
(for example 25%), it will be computed based on the nozzle diameter. (mm or %,
default: 25%)
--mmu-segmented-region-max-width N
Maximum width of a segmented region. Zero disables this feature. (mm (zero to
disable), default: 0)
--slice-closing-radius N
Cracks smaller than 2x gap closing radius are being filled during the triangle
mesh slicing. The gap closing operation may reduce the final print resolution,
therefore it is advisable to keep the value reasonably low. (mm, default: 0.049)
--slicing-mode Use "Even-odd" for 3DLabPrint airplane models. Use "Close holes" to close all
holes in the model. (regular, even_odd, close_holes; default: regular)
--wall-distribution-count N
The number of perimeters, counted from the center, over which the variation
needs to be spread. Lower values mean that the outer perimeters don't change in
width. (default: 1)
--wall-transition-angle N
When to create transitions between even and odd numbers of perimeters. A wedge
shape with an angle greater than this setting will not have transitions and no
perimeters will be printed in the center to fill the remaining space. Reducing
this setting reduces the number and length of these center perimeters, but may
leave gaps or overextrude. (°, default: 10)
--wall-transition-filter-deviation N
Prevent transitioning back and forth between one extra perimeter and one less.
This margin extends the range of extrusion widths which follow to [Minimum
perimeter width - margin, 2 * Minimum perimeter width + margin]. Increasing this
margin reduces the number of transitions, which reduces the number of extrusion
starts/stops and travel time. However, large extrusion width variation can lead
to under- or overextrusion problems. If expressed as a percentage (for example
25%), it will be computed based on the nozzle diameter. (mm or %, default: 25%)
--wall-transition-length N
When transitioning between different numbers of perimeters as the part becomes
thinner, a certain amount of space is allotted to split or join the perimeter
segments. If expressed as a percentage (for example 100%), it will be computed
based on the nozzle diameter. (mm or %, default: 100%)
--xy-size-compensation N
The object will be grown/shrunk in the XY plane by the configured value
(negative = inwards, positive = outwards). This might be useful for fine-tuning
hole sizes. (mm, default: 0)

current extruder to minimize tool changes). This affects raft too. (default: 1)
Extrusion Width:
--external-perimeter-extrusion-width N
Set this to a non-zero value to set a manual extrusion width for external
perimeters. If left zero, default extrusion width will be used if set, otherwise
1.125 x nozzle diameter will be used. If expressed as percentage (for example
200%), it will be computed over layer height. (mm or %, default: 0)
--extrusion-width N Set this to a non-zero value to allow a manual extrusion width. If left to zero,
Slic3r derives extrusion widths from the nozzle diameter (see the tooltips for
perimeter extrusion width, infill extrusion width etc). If expressed as
percentage (for example: 230%), it will be computed over layer height. (mm or %,
default: 0)
--first-layer-extrusion-width N
Set this to a non-zero value to set a manual extrusion width for first layer.

--infill-extrusion-width N
Set this to a non-zero value to set a manual extrusion width for infill. If left
zero, default extrusion width will be used if set, otherwise 1.125 x nozzle

infill and make your parts stronger. If expressed as percentage (for example
90%) it will be computed over layer height. (mm or %, default: 0)
--perimeter-extrusion-width N
Set this to a non-zero value to set a manual extrusion width for perimeters. You
may want to use thinner extrudates to get more accurate surfaces. If left zero,
default extrusion width will be used if set, otherwise 1.125 x nozzle diameter

--support-material-extrusion-width N
Set this to a non-zero value to set a manual extrusion width for support
material. If left zero, default extrusion width will be used if set, otherwise
nozzle diameter will be used. If expressed as percentage (for example 90%) it
will be computed over layer height. (mm or %, default: 0)
--top-infill-extrusion-width N
Set this to a non-zero value to set a manual extrusion width for infill for top
surfaces. You may want to use thinner extrudates to fill all narrow regions and
get a smoother finish. If left zero, default extrusion width will be used if
set, otherwise nozzle diameter will be used. If expressed as percentage (for

layer, and not its adjacent solid shells. (rectilinear, monotonic,
alignedrectilinear, concentric, hilbertcurve, archimedeanchords, octagramspiral;
default: monotonic)
--bridge-angle N Bridging angle override. If left to zero, the bridging angle will be calculated
automatically. Otherwise the provided angle will be used for all bridges. Use
180° for zero angle. (°, default: 0)
--fill-angle N Default base angle for infill orientation. Cross-hatching will be applied to
this. Bridges will be infilled using the best direction Slic3r can detect, so
this setting does not affect them. (°, default: 45)

hilbertcurve, archimedeanchords, octagramspiral, adaptivecubic, supportcubic,
lightning; default: stars)
--infill-every-layers N
This feature allows to combine infill and speed up your print by extruding
thicker infill layers while preserving thin perimeters, thus accuracy. (layers,
default: 1)
--infill-only-where-needed
This option will limit infill to the areas actually needed for supporting
ceilings (it will act as internal support material). If enabled, slows down the
G-code generation due to the multiple checks involved.
--solid-infill-below-area N
Force solid infill for regions having a smaller area than the specified
threshold. (mm², default: 70)
--solid-infill-every-layers N
This feature allows to force a solid layer every given number of layers. Zero to

(for example 50%) of a direct travel path. (mm or % (zero to disable), default:
0)
--bottom-solid-layers N

(top+bottom solid layers).
--external-perimeters-first
Print contour perimeters from the outermost one to the innermost one instead of
the default inverse order.
--extra-perimeters Add more perimeters when needed for avoiding gaps in sloping walls. Slic3r keeps
adding perimeters, until more than 70% of the loop immediately above is
supported.
--first-layer-height N
When printing with very low layer heights, you might still want to print a
thicker bottom layer to improve adhesion and tolerance for non perfect build
plates. (mm, default: 0.35)
--gap-fill-enabled Enables filling of gaps between perimeters and between the inner most perimeters
and infill.
--interface-shells Force the generation of solid shells between adjacent materials/volumes. Useful
for multi-extruder prints with translucent materials or manual soluble support
material.
--layer-height N This setting controls the height (and thus the total number) of the
slices/layers. Thinner layers give better accuracy but take more time to print.
(mm, default: 0.3)
--overhangs Experimental option to adjust flow for overhangs (bridge flow will be used), to
apply bridge speed to them and enable fan.
--perimeter-generator
Classic perimeter generator produces perimeters with constant extrusion width
and for very thin areas is used gap-fill. Arachne engine produces perimeters
with variable extrusion width. This setting also affects the Concentric infill.
(classic, arachne; default: arachne)
--perimeters N This option sets the number of perimeters to generate for each layer. Note that
Slic3r may increase this number automatically when it detects sloping surfaces
which benefit from a higher number of perimeters if the Extra Perimeters option
is enabled. ((minimum), default: 3)
--seam-position Position of perimeters starting points. (random, nearest, aligned, rear;
default: aligned)
--thick-bridges If enabled, bridges are more reliable, can bridge longer distances, but may look
worse. If disabled, bridges look better but are reliable just for shorter
bridged distances.

collapse them into a single trace).
--top-solid-layers N
Number of solid layers to generate on top surfaces. (default: 3)
--top-solid-min-thickness N
The number of top solid layers is increased above top_solid_layers if necessary
to satisfy minimum thickness of top shell. This is useful to prevent pillowing
effect when printing with variable layer height. (mm, default: 0)

--support-material-angle N
Use this setting to rotate the support material pattern on the horizontal plane.
(°, default: 0)

threshold value. If unchecked, supports will be generated inside the "Support
Enforcer" volumes only.
--support-material-bottom-contact-distance N

interface. If set to zero, support_material_contact_distance will be used for
both top and bottom contact Z distances. (mm, default: 0)

Number of interface layers to insert between the object(s) and support material.
Set to -1 to use support_material_interface_layers (layers, default: -1)
--support-material-buildplate-only

closing operation. Gaps smaller than the closing radius will be filled in. (mm,
default: 2)

bottom, regardless of whether normal support material is enabled or not and
regardless of any angle threshold. This is useful for getting more adhesion of

without support material. Set to zero for automatic detection (recommended).
(°, default: 0)
--support-material-with-sheath
Add a sheath (a single perimeter line) around the base support. This makes the
support more reliable, but also more difficult to remove.
--support-material-xy-spacing N
XY separation between an object and its support. If expressed as percentage (for
example 50%), it will be calculated over external perimeter width. (mm or %,
default: 50%)

--avoid-crossing-perimeters
Optimize travel moves in order to minimize the crossing of perimeters. This is
mostly useful with Bowden extruders which suffer from oozing. This feature slows
down both the print and the G-code generation.
--bed-custom-model ABCD
--bed-custom-texture ABCD
--bed-shape (default: 0x0,200x0,200x200,0x200)

This custom code is inserted at every layer change, right before the Z move.
Note that you can use placeholder variables for all Slic3r settings as well as
[layer_num] and [layer_z].
--between-objects-gcode ABCD
This code is inserted between objects when using sequential printing. By default
extruder and bed temperature are reset using non-wait command; however if M104,
M109, M140 or M190 are detected in this custom code, Slic3r will not add
temperature commands. Note that you can use placeholder variables for all Slic3r
settings, so you can put a "M109 S[first_layer_temperature]" command wherever
you want.
--bridge-acceleration N
This is the acceleration your printer will use for bridges. Set zero to disable
acceleration control for bridges. (mm/s², default: 0)
--bridge-fan-speed N
This fan speed is enforced during all bridges and overhangs. (%, default: 100)
--clip-multipart-objects
When printing multi-material objects, this settings will make Slic3r to clip the
overlapping object parts one by the other (2nd part will be clipped by the 1st,
3rd part will be clipped by the 1st and 2nd etc).

This G-code will be used as a code for the color change (default: M600)
--colorprint-heights N
Heights at which a filament change is to occur. (default: )
--complete-objects When printing multiple objects or copies, this feature will complete each object
before moving onto next one (and starting it from its bottom layer). This

acceleration at all. (mm/s², default: 0)
--deretract-speed N The speed for loading of a filament into extruder after retraction (it only
applies to the extruder motor). If left to zero, the retraction speed is used.

--disable-fan-first-layers N
You can set this to a positive value to disable fan at all during the first
layers, so that it does not make adhesion worse. (layers, default: 3)
--draft-shield With draft shield active, the skirt will be printed skirt_distance from the
object, possibly intersecting brim. Enabled = skirt is as tall as the highest
printed object. Limited = skirt is as tall as specified by skirt_height. This is
useful to protect an ABS or ASA print from warping and detaching from print bed
due to wind draft. (disabled, limited, enabled; default: disabled)
--duplicate-distance N
Distance used for the auto-arrange feature of the plater. (mm, default: 6)
--end-filament-gcode ABCD
This end procedure is inserted at the end of the output file, before the printer
end gcode (and before any toolchange from this filament in case of multimaterial
printers). Note that you can use placeholder variables for all PrusaSlicer
settings. If you have multiple extruders, the gcode is processed in extruder
order. (default: "; Filament-specific end gcode \n;END gcode for filament\n")
--end-gcode ABCD This end procedure is inserted at the end of the output file. Note that you can
use placeholder variables for all PrusaSlicer settings. (default: M104 S0 ; turn
off temperature\nG28 X0 ; home X axis\nM84 ; disable motors\n)
--extra-loading-move N

during load is exactly the same as it was moved back during unload. When
positive, it is loaded further, if negative, the loading move is shorter than
unloading. (mm, default: -2)

Set this to the clearance radius around your extruder. If the extruder is not
centered, choose the largest value for safety. This setting is used to check for
collisions and to display the graphical preview in the plater. (mm, default: 20)
--extruder-colour ABCD
This is only used in the Slic3r interface as a visual help. (default: "")
--extruder-offset If your firmware doesn't handle the extruder displacement you need the G-code to
take it into account. This option lets you specify the displacement of each
extruder with respect to the first one. It expects positive coordinates (they
will be subtracted from the XY coordinate). (mm, default: 0x0)
--extrusion-axis ABCD
Use this option to set the axis letter associated to your printer's extruder
(usually E but some printers use A). (default: E)
--extrusion-multiplier N
This factor changes the amount of flow proportionally. You may need to tweak
this setting to get nice surface finish and correct single wall widths. Usual
values are between 0.9 and 1.1. If you think you need to change this more, check
filament diameter and your firmware E steps. (default: 1)

--filament-cost N Enter your filament cost per kg here. This is only for statistical information.
(money/kg, default: 0)
--filament-density N

length to volume. Better is to calculate the volume directly through
displacement. (g/cm³, default: 0)
--filament-deretract-speed N
The speed for loading of a filament into extruder after retraction (it only
applies to the extruder motor). If left to zero, the retraction speed is used.

and do multiple measurements along the filament, then compute the average. (mm,
default: 1.75)
--filament-load-time N
Time for the printer firmware (or the Multi Material Unit 2.0) to load a new
filament during a tool change (when executing the T code). This time is added to
the total print time by the G-code time estimator. (s, default: 0)

volumetric speed of a print to the minimum of print and filament volumetric
speed. Set to zero for no limit. (mm³/s, default: 0)
--filament-minimal-purge-on-wipe-tower N
After a tool change, the exact position of the newly loaded filament inside the
nozzle may not be known, and the filament pressure is likely not yet stable.
Before purging the print head into an infill or a sacrificial object, Slic3r
will always prime this amount of material into the wipe tower to produce
successive infill or sacrificial object extrusions reliably. (mm³, default: 15)
--filament-notes ABCD
You can put your notes regarding the filament here. (default: "")

--filament-retract-before-travel N
Retraction is not triggered when travel moves are shorter than this length. (mm,
default: 2)
--filament-retract-before-wipe
With bowden extruders, it may be wise to do some amount of quick retract before
doing the wipe movement. (%, default: 0%)
--filament-retract-layer-change
This flag enforces a retraction whenever a Z move is done. (default: 0)
--filament-retract-length N
When retraction is triggered, filament is pulled back by the specified amount
(the length is measured on raw filament, before it enters the extruder). (mm
(zero to disable), default: 2)
--filament-retract-lift N
If you set this to a positive value, Z is quickly raised every time a retraction
is triggered. When using multiple extruders, only the setting for the first
extruder will be considered. (mm, default: 0)
--filament-retract-lift-above N
If you set this to a positive value, Z lift will only take place above the
specified absolute Z. You can tune this setting for skipping lift on the first
layers. (mm, default: 0)
--filament-retract-lift-below N
If you set this to a positive value, Z lift will only take place below the
specified absolute Z. You can tune this setting for limiting lift to the first
layers. (mm, default: 0)
--filament-retract-restart-extra N

this additional amount of filament. This setting is rarely needed. (mm, default:
0)
--filament-retract-speed N
The speed for retractions (it only applies to the extruder motor). (mm/s,
default: 40)
--filament-soluble Soluble material is most likely used for a soluble support. (default: 0)
--filament-spool-weight N
Enter weight of the empty filament spool. One may weigh a partially consumed
filament spool before printing and one may compare the measured weight with the
calculated weight of the filament with the spool to find out whether the amount
of filament on the spool is sufficient to finish the print. (g, default: 0)
--filament-toolchange-delay N
Time to wait after the filament is unloaded. May help to get reliable
toolchanges with flexible materials that may need more time to shrink to
original dimensions. (s, default: 0)

HIPS, EDGE, NGEN, PA, NYLON, PVA, PC, PP, PEI, PEEK, PEKK, POM, PSU, PVDF,
SCAFF; default: PLA)
--filament-unload-time N
Time for the printer firmware (or the Multi Material Unit 2.0) to unload a
filament during a tool change (when executing the T code). This time is added to
the total print time by the G-code time estimator. (s, default: 0)
--filament-unloading-speed N
Speed used for unloading the filament on the wipe tower (does not affect initial
part of unloading just after ramming). (mm/s, default: 90)
--filament-unloading-speed-start N
Speed used for unloading the tip of the filament immediately after ramming.
(mm/s, default: 100)
--filament-wipe This flag will move the nozzle while retracting to minimize the possible blob on
leaky extruders. (default: 0)
--first-layer-acceleration N
This is the acceleration your printer will use for first layer. Set zero to
disable acceleration control for first layer. (mm/s², default: 0)

--first-layer-bed-temperature N
Heated build plate temperature for the first layer. Set this to zero to disable
bed temperature control commands in the output. (°C, default: 0)
--first-layer-speed N
If expressed as absolute value in mm/s, this speed will be applied to all the
print moves of the first layer, regardless of their type. If expressed as a
percentage (for example: 40%) it will scale the default speeds. (mm/s or %,
default: 30)
--first-layer-speed-over-raft N
If expressed as absolute value in mm/s, this speed will be applied to all the
print moves of the first object layer above raft interface, regardless of their
type. If expressed as a percentage (for example: 40%) it will scale the default
speeds. (mm/s or %, default: 30)
--first-layer-temperature N
Nozzle temperature for the first layer. If you want to control temperature
manually during print, set this to zero to disable temperature control commands
in the output G-code. (°C, default: 200)
--full-fan-speed-layer N
Fan speed will be ramped up linearly from zero at layer
"disable_fan_first_layers" to maximum at layer "full_fan_speed_layer".
"full_fan_speed_layer" will be ignored if lower than "disable_fan_first_layers",
in which case the fan will be running at maximum allowed speed at layer
"disable_fan_first_layers" + 1. (default: 0)
--gcode-comments Enable this to get a commented G-code file, with each line explained by a
descriptive text. If you print from SD card, the additional weight of the file
could make your firmware slow down.
--gcode-flavor Some G/M-code commands, including temperature control and others, are not
universal. Set this option to your printer's firmware to get a compatible
output. The "No extrusion" flavor prevents PrusaSlicer from exporting any
extrusion value at all. (reprap, reprapfirmware, repetier, teacup, makerware,
marlin, marlin2, sailfish, mach3, machinekit, smoothie, no-extrusion; default:
reprap)
--gcode-label-objects
Enable this to add comments into the G-Code labeling print moves with what
object they belong to, which is useful for the Octoprint CancelObject plugin.
This settings is NOT compatible with Single Extruder Multi Material setup and
Wipe into Object / Wipe into Infill.
--gcode-resolution N
Maximum deviation of exported G-code paths from their full resolution
counterparts. Very high resolution G-code requires huge amount of RAM to slice
and preview, also a 3D printer may stutter not being able to process a high
resolution G-code in a timely manner. On the other hand, a low resolution G-code
will produce a low poly effect and because the G-code reduction is performed at
each layer independently, visible artifacts may be produced. (mm, default:
0.0125)
--gcode-substitutions ABCD
Find / replace patterns in G-code lines and substitute them. (default: )
--high-current-on-filament-swap
It may be beneficial to increase the extruder motor current during the filament
exchange sequence to allow for rapid ramming feed rates and to overcome
resistance when loading a filament with an ugly shaped tip.
--infill-acceleration N
This is the acceleration your printer will use for infill. Set zero to disable
acceleration control for infill. (mm/s², default: 0)
--infill-first This option will switch the print order of perimeters and infill, making the
latter first.
--after-layer-gcode ABCD, --layer-gcode ABCD
This custom code is inserted at every layer change, right after the Z move and
before the extruder moves to the first layer point. Note that you can use
placeholder variables for all Slic3r settings as well as [layer_num] and
[layer_z].
--max-fan-speed N This setting represents the maximum speed of your fan. (%, default: 100)
--max-layer-height N
This is the highest printable layer height for this extruder, used to cap the
variable layer height and support layer height. Maximum recommended layer height
is 75% of the extrusion width to achieve reasonable inter-layer adhesion. If set
to 0, layer height is limited to 75% of the nozzle diameter. (mm, default: 0)
--max-print-height N
Set this to the maximum height that can be reached by your extruder while
printing. (mm, default: 200)
--max-print-speed N When setting other speed settings to 0 Slic3r will autocalculate the optimal
speed in order to keep constant extruder pressure. This experimental setting is
used to set the highest print speed you want to allow. (mm/s, default: 80)
--max-volumetric-extrusion-rate-slope-negative N
This experimental setting is used to limit the speed of change in extrusion rate
for a transition from higher speed to lower speed. A value of 1.8 mm³/s²
ensures, that a change from the extrusion rate of 5.4 mm³/s (0.45 mm extrusion
width, 0.2 mm extrusion height, feedrate 60 mm/s) to 1.8 mm³/s (feedrate 20
mm/s) will take at least 2 seconds. (mm³/s², default: 0)
--max-volumetric-extrusion-rate-slope-positive N
This experimental setting is used to limit the speed of change in extrusion rate
for a transition from lower speed to higher speed. A value of 1.8 mm³/s²
ensures, that a change from the extrusion rate of 1.8 mm³/s (0.45 mm extrusion
width, 0.2 mm extrusion height, feedrate 20 mm/s) to 5.4 mm³/s (feedrate 60
mm/s) will take at least 2 seconds. (mm³/s², default: 0)
--max-volumetric-speed N
This experimental setting is used to set the maximum volumetric speed your
extruder supports. (mm³/s, default: 0)
--min-fan-speed N This setting represents the minimum PWM your fan needs to work. (%, default: 35)
--min-layer-height N
This is the lowest printable layer height for this extruder and limits the
resolution for variable layer height. Typical values are between 0.05 mm and 0.1
mm. (mm, default: 0.07)
--min-print-speed N Slic3r will not scale speed down below this speed. (mm/s, default: 10)
--min-skirt-length N
Generate no less than the number of skirt loops required to consume the
specified amount of filament on the bottom layer. For multi-extruder machines,
this minimum applies to each extruder. (mm, default: 0)
--notes ABCD You can put here your personal notes. This text will be added to the G-code
header comments.
--nozzle-diameter N This is the diameter of your extruder nozzle (for example: 0.5, 0.35 etc.) (mm,
default: 0.4)
--only-retract-when-crossing-perimeters
Disables retraction when the travel path does not exceed the upper layer's
perimeters (and thus any ooze will be probably invisible).
--ooze-prevention This option will drop the temperature of the inactive extruders to prevent
oozing. It will enable a tall skirt automatically and move extruders outside
such skirt when changing temperatures.
--output-filename-format ABCD
You can use all configuration options as variables inside this template. For
example: [layer_height], [fill_density] etc. You can also use [timestamp],
[year], [month], [day], [hour], [minute], [second], [version], [input_filename],
[input_filename_base]. (default: [input_filename_base].gcode)
--parking-pos-retraction N
Distance of the extruder tip from the position where the filament is parked when
unloaded. This should match the value in printer firmware. (mm, default: 92)
--pause-print-gcode ABCD
This G-code will be used as a code for the pause print (default: M601)
--perimeter-acceleration N
This is the acceleration your printer will use for perimeters. Set zero to
disable acceleration control for perimeters. (mm/s², default: 0)
--post-process ABCD If you want to process the output G-code through custom scripts, just list their
absolute paths here. Separate multiple scripts with a semicolon. Scripts will be
passed the absolute path to the G-code file as the first argument, and they can
access the Slic3r config settings by reading environment variables. (default: )
--preset-name ABCD
--preset-names ABCD Names of presets related to the physical printer (default: )
--printer-notes ABCD
You can put your notes regarding the printer here.
--printer-technology
Printer technology (FFF, SLA; default: FFF)
--remaining-times Emit M73 P[percent printed] R[remaining time in minutes] at 1 minute intervals
into the G-code to let the firmware show accurate remaining time. As of now only
the Prusa i3 MK3 firmware recognizes M73. Also the i3 MK3 firmware supports M73
Qxx Sxx for the silent mode.
--resolution N Minimum detail resolution, used to simplify the input file for speeding up the
slicing job and reducing memory usage. High-resolution models often carry more
detail than printers can render. Set to zero to disable any simplification and
use full resolution from input. (mm, default: 0)
--retract-before-travel N
Retraction is not triggered when travel moves are shorter than this length. (mm,
default: 2)
--retract-before-wipe
With bowden extruders, it may be wise to do some amount of quick retract before
doing the wipe movement. (%, default: 0%)
--retract-layer-change
This flag enforces a retraction whenever a Z move is done. (default: 0)
--retract-length N When retraction is triggered, filament is pulled back by the specified amount
(the length is measured on raw filament, before it enters the extruder). (mm
(zero to disable), default: 2)
--retract-length-toolchange N
When retraction is triggered before changing tool, filament is pulled back by
the specified amount (the length is measured on raw filament, before it enters
the extruder). (mm (zero to disable), default: 10)
--retract-lift N If you set this to a positive value, Z is quickly raised every time a retraction
is triggered. When using multiple extruders, only the setting for the first
extruder will be considered. (mm, default: 0)
--retract-lift-above N
If you set this to a positive value, Z lift will only take place above the
specified absolute Z. You can tune this setting for skipping lift on the first
layers. (mm, default: 0)
--retract-lift-below N
If you set this to a positive value, Z lift will only take place below the
specified absolute Z. You can tune this setting for limiting lift to the first
layers. (mm, default: 0)
--retract-restart-extra N
When the retraction is compensated after the travel move, the extruder will push
this additional amount of filament. This setting is rarely needed. (mm, default:
0)
--retract-restart-extra-toolchange N
When the retraction is compensated after changing tool, the extruder will push
this additional amount of filament. (mm, default: 0)
--retract-speed N The speed for retractions (it only applies to the extruder motor). (mm/s,
default: 40)
--silent-mode The firmware supports stealth mode
--single-extruder-multi-material
The printer multiplexes filaments into a single hot end.
--single-extruder-multi-material-priming
If enabled, all printing extruders will be primed at the front edge of the print
bed at the start of the print.
--skirt-distance N Distance between skirt and brim (when draft shield is not used) or objects. (mm,
default: 6)
--skirt-height N Height of skirt expressed in layers. (layers, default: 1)
--skirts N Number of loops for the skirt. If the Minimum Extrusion Length option is set,
the number of loops might be greater than the one configured here. Set this to
zero to disable skirt completely. (default: 1)
--slowdown-below-layer-time N
If layer print time is estimated below this number of seconds, print moves speed
will be scaled down to extend duration to this value. (approximate seconds,
default: 5)
--solid-layers N Number of solid layers to generate on top and bottom surfaces.
--solid-min-thickness N
Minimum thickness of a top / bottom shell
--spiral-vase This feature will raise Z gradually while printing a single-walled object in
order to remove any visible seam. This option requires a single perimeter, no
infill, no top solid layers and no support material. You can still set any
number of bottom solid layers as well as skirt/brim loops. It won't work when
printing more than one single object.
--standby-temperature-delta N
Temperature difference to be applied when an extruder is not active. Enables a
full-height "sacrificial" skirt on which the nozzles are periodically wiped.
(∆°C, default: -5)
--start-filament-gcode ABCD
This start procedure is inserted at the beginning, after any printer start gcode
(and after any toolchange to this filament in case of multi-material printers).
This is used to override settings for a specific filament. If PrusaSlicer
detects M104, M109, M140 or M190 in your custom codes, such commands will not be
prepended automatically so you're free to customize the order of heating
commands and other custom actions. Note that you can use placeholder variables
for all PrusaSlicer settings, so you can put a "M109 S[first_layer_temperature]"
command wherever you want. If you have multiple extruders, the gcode is
processed in extruder order. (default: "; Filament gcode\n")
--start-gcode ABCD This start procedure is inserted at the beginning, after bed has reached the
target temperature and extruder just started heating, and before extruder has
finished heating. If PrusaSlicer detects M104 or M190 in your custom codes, such
commands will not be prepended automatically so you're free to customize the
order of heating commands and other custom actions. Note that you can use
placeholder variables for all PrusaSlicer settings, so you can put a "M109
S[first_layer_temperature]" command wherever you want. (default: G28 ; home all
axes\nG1 Z5 F5000 ; lift nozzle\n)
--temperature N Nozzle temperature for layers after the first one. Set this to zero to disable
temperature control commands in the output G-code. (°C, default: 200)
--template-custom-gcode ABCD
This G-code will be used as a custom code
--thumbnails Picture sizes to be stored into a .gcode and .sl1 / .sl1s files, in the
following format: "XxY, XxY, ..." (default: )
--thumbnails-format Format of G-code thumbnails: PNG for best quality, JPG for smallest size, QOI
for low memory firmware (PNG, JPG, QOI; default: PNG)
--toolchange-gcode ABCD
This custom code is inserted before every toolchange. Placeholder variables for
all PrusaSlicer settings as well as {toolchange_z}, {previous_extruder} and
{next_extruder} can be used. When a tool-changing command which changes to the
correct extruder is included (such as T{next_extruder}), PrusaSlicer will emit
no other such command. It is therefore possible to script custom behaviour both
before and after the toolchange.
--travel-speed N Speed for travel moves (jumps between distant extrusion points). (mm/s, default:
130)
--travel-speed-z N Speed for movements along the Z axis. When set to zero, the value is ignored and
regular travel speed is used instead. (mm/s, default: 0)
--use-firmware-retraction
This experimental setting uses G10 and G11 commands to have the firmware handle
the retraction. This is only supported in recent Marlin.
--use-relative-e-distances
If your firmware requires relative E values, check this, otherwise leave it
unchecked. Most firmwares use absolute values.
--use-volumetric-e This experimental setting uses outputs the E values in cubic millimeters instead
of linear millimeters. If your firmware doesn't already know filament
diameter(s), you can put commands like 'M200 D[filament_diameter_0] T0' in your
start G-code in order to turn volumetric mode on and use the filament diameter
associated to the filament selected in Slic3r. This is only supported in recent
Marlin.
--variable-layer-height
Some printers or printer setups may have difficulties printing with a variable
layer height. Enabled by default.
--wipe This flag will move the nozzle while retracting to minimize the possible blob on
leaky extruders. (default: 0)
--wipe-tower Multi material printers may need to prime or purge extruders on tool changes.
Extrude the excess material into the wipe tower.
--wipe-tower-bridging N
Maximal distance between supports on sparse infill sections. (mm, default: 10)
--wipe-tower-brim-width N
Wipe tower brim width (mm, default: 2)
--wipe-tower-no-sparse-layers
If enabled, the wipe tower will not be printed on layers with no toolchanges. On
layers with a toolchange, extruder will travel downward to print the wipe tower.
User is responsible for ensuring there is no collision with the print.
--wipe-tower-rotation-angle N
Wipe tower rotation angle with respect to x-axis. (°, default: 0)
--wipe-tower-width N
Width of a wipe tower (mm, default: 60)
--wipe-tower-x N X coordinate of the left front corner of a wipe tower (mm, default: 180)
--wipe-tower-y N Y coordinate of the left front corner of a wipe tower (mm, default: 140)
--wiping-volumes-extruders N
This vector saves required volumes to change from/to each tool used on the wipe
tower. These values are used to simplify creation of the full purging volumes
below. (default: 70,70,70,70,70,70,70,70,70,70)
--wiping-volumes-matrix N
This matrix describes volumes (in cubic milimetres) required to purge the new
filament on the wipe tower for any given pair of tools. (default:
0,140,140,140,140,140,0,140,140,140,140,140,0,140,140,140,140,140,0,140,140,140,140,140,0)
--z-offset N This value will be added (or subtracted) from all the Z coordinates in the
output G-code. It is used to compensate for bad Z endstop position: for example,
if your endstop zero actually leaves the nozzle 0.3mm far from the print bed,
set this to -0.3 (or fix your endstop). (mm, default: 0)
Advanced:
--bridge-flow-ratio N
This factor affects the amount of plastic for bridging. You can decrease it
slightly to pull the extrudates and prevent sagging, although default settings
are usually good and you should experiment with cooling (use a fan) before
tweaking this. (default: 1)
--elefant-foot-compensation N
The first layer will be shrunk in the XY plane by the configured value to
compensate for the 1st layer squish aka an Elephant Foot effect. (mm, default:
0)
--infill-anchor N Connect an infill line to an internal perimeter with a short segment of an
additional perimeter. If expressed as percentage (example: 15%) it is calculated
over infill extrusion width. PrusaSlicer tries to connect two close infill lines
to a short perimeter segment. If no such perimeter segment shorter than
infill_anchor_max is found, the infill line is connected to a perimeter segment
at just one side and the length of the perimeter segment taken is limited to
this parameter, but no longer than anchor_length_max. Set this parameter to zero
to disable anchoring perimeters connected to a single infill line. (mm or %,
default: 600%)
--infill-anchor-max N
Connect an infill line to an internal perimeter with a short segment of an
additional perimeter. If expressed as percentage (example: 15%) it is calculated
over infill extrusion width. PrusaSlicer tries to connect two close infill lines
to a short perimeter segment. If no such perimeter segment shorter than this
parameter is found, the infill line is connected to a perimeter segment at just
one side and the length of the perimeter segment taken is limited to
infill_anchor, but no longer than this parameter. Set this parameter to zero to
disable anchoring. (mm or %, default: 50)
--infill-overlap N This setting applies an additional overlap between infill and perimeters for
better bonding. Theoretically this shouldn't be needed, but backlash might cause
gaps. If expressed as percentage (example: 15%) it is calculated over perimeter
extrusion width. (mm or %, default: 25%)
--min-bead-width N Width of the perimeter that will replace thin features (according to the Minimum
feature size) of the model. If the Minimum perimeter width is thinner than the
thickness of the feature, the perimeter will become as thick as the feature
itself. If expressed as a percentage (for example 85%), it will be computed
based on the nozzle diameter. (mm or %, default: 85%)
--min-feature-size N
Minimum thickness of thin features. Model features that are thinner than this
value will not be printed, while features thicker than the Minimum feature size
will be widened to the Minimum perimeter width. If expressed as a percentage
(for example 25%), it will be computed based on the nozzle diameter. (mm or %,
default: 25%)
--mmu-segmented-region-max-width N
Maximum width of a segmented region. Zero disables this feature. (mm (zero to
disable), default: 0)
--slice-closing-radius N
Cracks smaller than 2x gap closing radius are being filled during the triangle
mesh slicing. The gap closing operation may reduce the final print resolution,
therefore it is advisable to keep the value reasonably low. (mm, default: 0.049)
--slicing-mode Use "Even-odd" for 3DLabPrint airplane models. Use "Close holes" to close all
holes in the model. (regular, even_odd, close_holes; default: regular)
--wall-distribution-count N
The number of perimeters, counted from the center, over which the variation
needs to be spread. Lower values mean that the outer perimeters don't change in
width. (default: 1)
--wall-transition-angle N
When to create transitions between even and odd numbers of perimeters. A wedge
shape with an angle greater than this setting will not have transitions and no
perimeters will be printed in the center to fill the remaining space. Reducing
this setting reduces the number and length of these center perimeters, but may
leave gaps or overextrude. (°, default: 10)
--wall-transition-filter-deviation N
Prevent transitioning back and forth between one extra perimeter and one less.
This margin extends the range of extrusion widths which follow to [Minimum
perimeter width - margin, 2 * Minimum perimeter width + margin]. Increasing this
margin reduces the number of transitions, which reduces the number of extrusion
starts/stops and travel time. However, large extrusion width variation can lead
to under- or overextrusion problems. If expressed as a percentage (for example
25%), it will be computed based on the nozzle diameter. (mm or %, default: 25%)
--wall-transition-length N
When transitioning between different numbers of perimeters as the part becomes
thinner, a certain amount of space is allotted to split or join the perimeter
segments. If expressed as a percentage (for example 100%), it will be computed
based on the nozzle diameter. (mm or %, default: 100%)
--xy-size-compensation N
The object will be grown/shrunk in the XY plane by the configured value
(negative = inwards, positive = outwards). This might be useful for fine-tuning
hole sizes. (mm, default: 0)
Extruders:
--extruder N The extruder to use (unless more specific extruder settings are specified). This
value overrides perimeter and infill extruders, but not the support extruders.
--infill-extruder N The extruder to use when printing infill. (default: 1)
--perimeter-extruder N
The extruder to use when printing perimeters and brim. First extruder is 1.
(default: 1)

The extruder to use when printing support material, raft and skirt (1+, 0 to use
the current extruder to minimize tool changes). (default: 1)
--support-material-interface-extruder N
The extruder to use when printing support material interface (1+, 0 to use the
current extruder to minimize tool changes). This affects raft too. (default: 1)
Extrusion Width:
--external-perimeter-extrusion-width N
Set this to a non-zero value to set a manual extrusion width for external
perimeters. If left zero, default extrusion width will be used if set, otherwise
1.125 x nozzle diameter will be used. If expressed as percentage (for example
200%), it will be computed over layer height. (mm or %, default: 0)
--extrusion-width N Set this to a non-zero value to allow a manual extrusion width. If left to zero,
Slic3r derives extrusion widths from the nozzle diameter (see the tooltips for
perimeter extrusion width, infill extrusion width etc). If expressed as
percentage (for example: 230%), it will be computed over layer height. (mm or %,
default: 0)
--first-layer-extrusion-width N
Set this to a non-zero value to set a manual extrusion width for first layer.
You can use this to force fatter extrudates for better adhesion. If expressed as
percentage (for example 120%) it will be computed over first layer height. If
set to zero, it will use the default extrusion width. (mm or %, default: 200%)
--infill-extrusion-width N
Set this to a non-zero value to set a manual extrusion width for infill. If left
zero, default extrusion width will be used if set, otherwise 1.125 x nozzle
diameter will be used. You may want to use fatter extrudates to speed up the
infill and make your parts stronger. If expressed as percentage (for example
90%) it will be computed over layer height. (mm or %, default: 0)
--perimeter-extrusion-width N
Set this to a non-zero value to set a manual extrusion width for perimeters. You
may want to use thinner extrudates to get more accurate surfaces. If left zero,
default extrusion width will be used if set, otherwise 1.125 x nozzle diameter
will be used. If expressed as percentage (for example 200%) it will be computed
over layer height. (mm or %, default: 0)
--solid-infill-extrusion-width N
Set this to a non-zero value to set a manual extrusion width for infill for
solid surfaces. If left zero, default extrusion width will be used if set,
otherwise 1.125 x nozzle diameter will be used. If expressed as percentage (for
example 90%) it will be computed over layer height. (mm or %, default: 0)
--support-material-extrusion-width N
Set this to a non-zero value to set a manual extrusion width for support
material. If left zero, default extrusion width will be used if set, otherwise
nozzle diameter will be used. If expressed as percentage (for example 90%) it
will be computed over layer height. (mm or %, default: 0)
--top-infill-extrusion-width N
Set this to a non-zero value to set a manual extrusion width for infill for top
surfaces. You may want to use thinner extrudates to fill all narrow regions and
get a smoother finish. If left zero, default extrusion width will be used if
set, otherwise nozzle diameter will be used. If expressed as percentage (for
example 90%) it will be computed over layer height. (mm or %, default: 0)
Fuzzy Skin:
--fuzzy-skin Fuzzy skin type. (none, external, all; default: none)
--fuzzy-skin-point-dist N

perpendicular to the perimeter wall. (mm, default: 0.3)
Infill:

Fill pattern for bottom infill. This only affects the bottom external visible
layer, and not its adjacent solid shells. (rectilinear, monotonic,
alignedrectilinear, concentric, hilbertcurve, archimedeanchords, octagramspiral;
default: monotonic)
--bridge-angle N Bridging angle override. If left to zero, the bridging angle will be calculated
automatically. Otherwise the provided angle will be used for all bridges. Use
180° for zero angle. (°, default: 0)
--fill-angle N Default base angle for infill orientation. Cross-hatching will be applied to
this. Bridges will be infilled using the best direction Slic3r can detect, so
this setting does not affect them. (°, default: 45)
--fill-density Density of internal infill, expressed in the range 0% - 100%. (%, default: 20%)
--fill-pattern Fill pattern for general low-density infill. (rectilinear, alignedrectilinear,
grid, triangles, stars, cubic, line, concentric, honeycomb, 3dhoneycomb, gyroid,
hilbertcurve, archimedeanchords, octagramspiral, adaptivecubic, supportcubic,
lightning; default: stars)
--infill-every-layers N
This feature allows to combine infill and speed up your print by extruding
thicker infill layers while preserving thin perimeters, thus accuracy. (layers,
default: 1)
--infill-only-where-needed
This option will limit infill to the areas actually needed for supporting
ceilings (it will act as internal support material). If enabled, slows down the
G-code generation due to the multiple checks involved.
--solid-infill-below-area N
Force solid infill for regions having a smaller area than the specified
threshold. (mm², default: 70)
--solid-infill-every-layers N
This feature allows to force a solid layer every given number of layers. Zero to
disable. You can set this to any value (for example 9999); Slic3r will
automatically choose the maximum possible number of layers to combine according
to nozzle diameter and layer height. (layers, default: 0)
--top-fill-pattern, --external-fill-pattern, --solid-fill-pattern
Fill pattern for top infill. This only affects the top visible layer, and not
its adjacent solid shells. (rectilinear, monotonic, alignedrectilinear,
concentric, hilbertcurve, archimedeanchords, octagramspiral; default: monotonic)
Ironing:

than this value, avoid crossing perimeters is not applied for this travel path.
Detour length could be specified either as an absolute value or as percentage
(for example 50%) of a direct travel path. (mm or % (zero to disable), default:
0)
--bottom-solid-layers N

--bottom-solid-min-thickness N
The number of bottom solid layers is increased above bottom_solid_layers if
necessary to satisfy minimum thickness of bottom shell. (mm, default: 0)
--ensure-vertical-shell-thickness
Add solid infill near sloping surfaces to guarantee the vertical shell thickness
(top+bottom solid layers).
--external-perimeters-first
Print contour perimeters from the outermost one to the innermost one instead of
the default inverse order.
--extra-perimeters Add more perimeters when needed for avoiding gaps in sloping walls. Slic3r keeps
adding perimeters, until more than 70% of the loop immediately above is
supported.
--first-layer-height N
When printing with very low layer heights, you might still want to print a
thicker bottom layer to improve adhesion and tolerance for non perfect build
plates. (mm, default: 0.35)
--gap-fill-enabled Enables filling of gaps between perimeters and between the inner most perimeters
and infill.
--interface-shells Force the generation of solid shells between adjacent materials/volumes. Useful
for multi-extruder prints with translucent materials or manual soluble support
material.
--layer-height N This setting controls the height (and thus the total number) of the
slices/layers. Thinner layers give better accuracy but take more time to print.
(mm, default: 0.3)
--overhangs Experimental option to adjust flow for overhangs (bridge flow will be used), to
apply bridge speed to them and enable fan.
--perimeter-generator
Classic perimeter generator produces perimeters with constant extrusion width
and for very thin areas is used gap-fill. Arachne engine produces perimeters
with variable extrusion width. This setting also affects the Concentric infill.
(classic, arachne; default: arachne)
--perimeters N This option sets the number of perimeters to generate for each layer. Note that
Slic3r may increase this number automatically when it detects sloping surfaces
which benefit from a higher number of perimeters if the Extra Perimeters option
is enabled. ((minimum), default: 3)
--seam-position Position of perimeters starting points. (random, nearest, aligned, rear;
default: aligned)
--thick-bridges If enabled, bridges are more reliable, can bridge longer distances, but may look
worse. If disabled, bridges look better but are reliable just for shorter
bridged distances.
--thin-walls Detect single-width walls (parts where two extrusions don't fit and we need to
collapse them into a single trace).
--top-solid-layers N
Number of solid layers to generate on top surfaces. (default: 3)
--top-solid-min-thickness N
The number of top solid layers is increased above top_solid_layers if necessary
to satisfy minimum thickness of top shell. This is useful to prevent pillowing
effect when printing with variable layer height. (mm, default: 0)
