So, what's this Slic3r?
Slic3r is mainly a toolpath generator for 3D printers: it reads 3D models (STL, OBJ, AMF, 3MF) and it converts them into G-code instructions for 3D printers. But it does much more than that, see the features list below.
Slic3r was born in 2011 within the RepRap community and thanks to its high configurability became the swiss-army knife for 3D printing. It served as a platform for experimenting several new ideas that later became technology standards, such as multiple extruders, brim, variable-height layers, per-object settings, modifiers, post-processing scripts, G-code macros and more. Despite being based on volunteer efforts, Slic3r is still pushing the boundaries of 3D printing.
Slic3r is:
- Open: it is totally open source and it's independent from any commercial company or printer manufacturer. We want to keep 3D printing open and free.
- Compatible: it supports all the known G-code dialects (Marlin, Repetier, Mach3, LinuxCNC, Machinekit, Smoothie, Makerware, Sailfish).
- Advanced: many configuration options allow for fine-tuning and full control. While novice users often need just few options, Slic3r is mostly used by advanced users.
- Community-driven: new features or issues are discussed in the GitHub repository. Join our collaborative effort and help improve it!
- Robust: the codebase includes more than 1,000 unit and regression tests, collected in 6 years of development.
- Modular: the core of Slic3r is libslic3r, a C++ library that provides a granular API and reusable components.
- Embeddable: a complete and powerful command line interface allows to use Slic3r from the shell or to integrate it in server-side applications.
- Powerful: see the list below!

Features
(Most of these are also available in the command line interface.)
- G-code generation for FFF/FDM printers;
- conversion between STL, OBJ, AMF, 3MF and POV formats;
- auto-repair of non-manifold meshes (and ability to re-export them);
- SVG export of slices;
- built-in USB/serial host controller, supporting multiple simultaneous printers each one with a spool queue;
- OctoPrint integration (send to printer);
- built-in projector and host for DLP printers;
- tool for cutting meshes in multiple solid parts with visual preview (also in batch using a grid);
- tool for extruding 2.5D TIN meshes.
What language is it written in?
The core parts of Slic3r are written in C++11, with multithreading. The graphical interface is in the process of being ported to C++14.

How can I invoke Slic3r using the command line?
Usage: slic3r.pl [ OPTIONS ] [ file.stl ] [ file2.stl ] ...
--help Output this usage screen and exit
--version Output the version of Slic3r and exit
--save Save configuration to the specified file
--load Load configuration from the specified file. It can be used
more than once to load options from multiple files.
-o, --output 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.
Non-slicing actions (no G-code will be generated):
--repair Repair given STL files and save them as _fixed.obj
--cut Cut given input files at given Z (relative) and export
them as _upper.stl and _lower.stl
--split Split the shells contained in given STL file into several STL files
--info Output information about the supplied file(s) and exit
-j, --threads Number of threads to use (1+, default: 2)
GUI options:
--gui Forces the GUI launch instead of command line slicing (if you
supply a model file, it will be loaded into the plater)
--no-gui Forces the command line slicing instead of gui.
This takes precedence over --gui if both are present.
--autosave Automatically export current configuration to the specified file
Output options:
--output-filename-format
Output file name format; all config options enclosed in brackets
will be replaced by their values, as well as [input_filename_base]
and [input_filename] (default: [input_filename_base].gcode)
--post-process Generated G-code will be processed with the supplied script;
call this more than once to process through multiple scripts.
--export-svg Export a SVG file containing slices instead of G-code.
-m, --merge If multiple files are supplied, they will be composed into a single
print rather than processed individually.
