_Q: Oh cool, a new RepRap slicer?_
|
|
|
|
A: Yes.
|
|
|
|
Slic3r [](https://travis-ci.org/alexrj/Slic3r)
|
|
======
|
|
|
|
Slic3r takes 3D models (STL, OBJ, AMF) and converts them into G-code instructions for
|
|
3D printers. It's compatible with any modern printer based on the RepRap toolchain,
|
|
including all those based on the Marlin, Sprinter and Repetier firmware. It also works
|
|
with Mach3, LinuxCNC and Machinekit controllers.
|
|
|
|
See the [project homepage](http://slic3r.org/) at slic3r.org and the
|
|
[manual](http://manual.slic3r.org/) for more information.
|
|
|
|
### What language is it written in?
|
|
|
|
The core geometric algorithms and data structures are written in C++,
|
|
and Perl is used for high-level flow abstraction, GUI and testing.
|
|
If you're wondering why Perl, see http://xkcd.com/224/
|
|
|
|
The C++ API is public and its use in other projects is encouraged.
|
|
The goal is to make Slic3r fully modular so that any part of its logic
|
|
can be used separately.
|
|
|
|
### What are Slic3r's main features?
|
|
|
|
Key features are:
|
|
|
|
* **multi-platform** (Linux/Mac/Win) and packaged as standalone-app with no dependencies required
|
|
* complete **command-line interface** to use it with no GUI
|
|
* multi-material **(multiple extruders)** object printing
|
|
* multiple G-code flavors supported (RepRap, Makerbot, Mach3, Machinekit etc.)
|
|
* ability to plate **multiple objects having distinct print settings**
|
|
* **multithread** processing
|
|
* **STL auto-repair** (tolerance for broken models)
|
|
* wide automated unit testing
|
|
|
|
Other major features are:
|
|
|
|
* combine infill every 'n' perimeters layer to speed up printing
|
|
* **3D preview** (including multi-material files)
|
|
* **multiple layer heights** in a single print
|
|
* **spiral vase** mode for bumpless vases
|
|
* fine-grained configuration of speed, acceleration, extrusion width
|
|
* several infill patterns including honeycomb, spirals, Hilbert curves
|
|
* support material, raft, brim, skirt
|
|
* **standby temperature** and automatic wiping for multi-extruder printing
|
|
* customizable **G-code macros** and output filename with variable placeholders
|
|
* support for **post-processing scripts**
|
|
* **cooling logic** controlling fan speed and dynamic print speed
|
|
|
|
### How to install?
|
|
|
|
You can just download a precompiled package from [slic3r.org](http://slic3r.org/);
|
|
it will run without the need for any dependency.
|
|
|
|
If you want to compile the source yourself just do the following (checkout
|
|
[slic3r.org](http://slic3r.org/download) for more details):
|
|
|
|
```
|
|
$ git clone https://github.com/alexrj/Slic3r.git
|
|
$ cd Slic3r
|
|
$ perl Build.PL --sudo
|
|
$ perl Build.PL --sudo --gui
|
|
$ ./slic3r.pl
|
|
```
|
|
|
|
### Can I help?
|
|
|
|
Sure! Drop me a line at aar@cpan.org. You can also
|
|
find me in #reprap and in #slic3r on FreeNode with the nickname _Sound_.
|
|
Before sending patches and pull requests contact me to discuss your proposed
|
|
changes: this way we'll ensure nobody wastes their time and no conflicts arise
|
|
in development.

### How can I invoke slic3r.pl using the command line?

|
-o, --output <file> File to output gcode to (by default, the file will be saved
|
|
into the same directory as the input file using the
|
|
--output-filename-format to generate the filename.) If a

directory is specified for this option, the output will
|
|
be saved under that directory, and the filename will be
|
|
generated by --output-filename-format.
