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 as well as AMF;
|
|
* powerful command line interface;
|
|
* easy GUI;
|
|
* multithreaded;
|
|
* 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;
|
|
* support material;
|
|
* cooling and fan control;
|
|
* 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;
|
|
* more fill patterns.
|
|
|
|
## Is it usable already? Any known limitation?
|
|
|
|
Sure, it's very usable. Remember that:
|
|
|
|
* it only works well with manifold and clean 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 licensed under the _GNU Affero General Public License, version 3_.

|
|
|
|
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
|
|
|
|
## How can I integrate Slic3r with Pronterface?
|
|
|
|
Put this into *slicecommand*:
|
|
|
|
slic3r.pl $s --load config.ini --output $o
|
|
|
|
And this into *sliceoptscommand*:
|
|
|
|
slic3r.pl --load config.ini --ignore-nonexistent-config
|
|
|
|
Replace `slic3r.pl` with the full path to the slic3r executable and `config.ini`
|
|
with the full path of your config file (put it in your home directory or where
|
|
you like).
|
|
On Mac, the executable has a path like this:
|
|
|
|
/Applications/Slic3r.app/Contents/MacOS/slic3r
|
|
|
|
## How can I specify a custom filename format for output G-code files?
|
|
|
|
You can specify a filename format by using any of the config options.
|
|
Just enclose them in square brackets, and Slic3r will replace them upon
|
|
exporting.
|
|
The additional `[input_filename]` and `[input_filename_base]` options will
|
|
be replaced by the input file name (in the second case, the .stl extension
|
|
is stripped).
|
|
|
|
The default format is `[input_filename_base].gcode`, meaning that if you slice
|
|
a *foo.stl* file, the output will be saved to *foo.gcode*.
|
|
|
|
See below for more complex examples:
|
|
|
|
[input_filename_base]_h[layer_height]_p[perimeters]_s[solid_layers].gcode
|
|
[input_filename]_center[print_center]_[layer_height]layers.gcode
|
|
