_Q: Oh cool, a new RepRap slicer?_
A: Yes.
# Slic3r
## What's it?
Slic3r is an STL-to-GCODE translator for RepRap 3D printers, aiming to
be a modern and fast alternative to Skeinforge.
See the [project homepage](http://slic3r.org/) at slic3r.org
for more information.
## What language is it written in?
Proudly Perl, with some parts in C++.
If you're wondering why Perl, see http://xkcd.com/224/
## What's its current status?
Slic3r current key features are:
* multi-platform (Linux/Mac/Win) and packaged as standalone-app with no dependencies required;
* easy configuration/calibration;
* read binary and ASCII STL files;
* powerful command line interface;
* easy GUI
* multiple infill patterns, with customizable density and angle;
* retraction;
* skirt;
* infill every N layers (like the "Skin" plugin for Skeinforge);
* detect optimal infill direction for bridges;
* save configuration profiles;
* center print around bed center point;
* multiple solid layers near horizontal external surfaces;
* ability to scale, rotate and duplicate input object;
* customizable initial and final GCODE;
* use different speed for bottom layer and perimeters.
Experimental features include:
* generation of G2/G3 commands for native arcs;
* G0 commands for fast retraction.
Roadmap includes the following goals:
* output some statistics;
* support material for internal perimeters;
* new and better GUI;
* cool;
* other fill patterns.
## Is it usable already? Any known limitation?
Sure, it's very usable. Remember that:
* it doesn't currently support single-walled parts (such as thin calibration objects);
* it doesn't generate support material;
* it only works well with manifold models (check them with Meshlab or Netfabb or http://cloud.netfabb.com/).
## How to install?
It's very easy. See the [project homepage](http://slic3r.org/)
for instructions and links to the precompiled packages.
## Can I help?
Sure! Send patches and/or drop me a line at aar@cpan.org. You can also
find me in #reprap on FreeNode with the nickname _Sound_.
## What's Slic3r license?
Slic3r is dual-licensed under the _Perl Artistic License_ and the _AGPLv3_.
The author is Alessandro Ranellucci (me).
## How can I invoke slic3r.pl using the command line?
Usage: slic3r.pl [ OPTIONS ] file.stl
--help Output this usage screen and exit
--save <file> Save configuration to the specified file
--load <file> Load configuration from the specified file
-o, --output File to output gcode to (default: <inputfile>.gcode)
Printer options:
--nozzle-diameter Diameter of nozzle in mm (default: 0.5)
--print-center Coordinates of the point to center the print around
(default: 100,100)
--use-relative-e-distances
Use relative distances for extrusion in GCODE output
--no-extrusion Do not output any E value in GCODE
--z-offset Additional height in mm to add to vertical coordinates
(+/-, default: 0)
--gcode-arcs Use G2/G3 commands for native arcs (experimental, not supported
by all firmwares)
Filament options:
--filament-diameter Diameter in mm of your raw filament (default: 3)
--filament-packing-density
Ratio of the extruded volume over volume pushed
into the extruder (default: 1)
--temperature Extrusion temperature (default: 200)
Speed options:
--print-feed-rate Speed of print moves in mm/sec (default: 60)
--travel-feed-rate Speed of non-print moves in mm/sec (default: 130)
--perimeter-feed-rate
Speed of print moves for perimeters in mm/sec (default: 60)
--bottom-layer-speed-ratio
Factor to increase/decrease speeds on bottom
layer by (default: 0.3)
Accuracy options:
--layer-height Layer height in mm (default: 0.4)
--first-layer-height-ratio
Multiplication factor for the height to slice and print the first
layer with (> 0, default: 1)
--infill-every-layers
Infill every N layers (default: 1)
Print options:
--perimeters Number of perimeters/horizontal skins (range: 1+,
default: 3)
--solid-layers Number of solid layers to do for top/bottom surfaces
(range: 1+, default: 3)
--fill-density Infill density (range: 0-1, default: 0.4)
--fill-angle Infill angle in degrees (range: 0-90, default: 0)
--fill-pattern Pattern to use to fill non-solid layers (default: rectilinear)
--solid-fill-pattern Pattern to use to fill solid layers (default: rectilinear)
--start-gcode Load initial gcode from the supplied file. This will overwrite
the default command (home all axes [G28]).
--end-gcode Load final gcode from the supplied file. This will overwrite
the default commands (turn off temperature [M104 S0],
home X axis [G28 X], disable motors [M84]).
Retraction options:
--retract-length Length of retraction in mm when pausing extrusion
(default: 1)
--retract-speed Speed for retraction in mm/sec (default: 40)
--retract-restart-extra
Additional amount of filament in mm to push after
compensating retraction (default: 0)
--retract-before-travel
Only retract before travel moves of this length (default: 2)
--retract-lift Lift Z by the given distance in mm when retracting (default: 0)
Skirt options:
--skirts Number of skirts to draw (default: 1)
--skirt-distance Distance in mm between innermost skirt and object
(default: 6)
--skirt-height Height of skirts to draw (expressed in layers, default: 1)
Transform options:
--scale Factor for scaling input object (default: 1)
--rotate Rotation angle in degrees (0-360, default: 0)
--duplicate-x Number of items along X axis (1+, default: 1)
--duplicate-y Number of items along Y axis (1+, default: 1)
--duplicate-distance Distance in mm between copies (default: 6)
If you want to change a preset file, just do
slic3r.pl --load config.ini --layer-height 0.25 --save config.ini
If you want to slice a file overriding an option contained in your preset file:
slic3r.pl --load config.ini --layer-height 0.25 file.stl
