SuperSlicer

A PrusaSlicer fork (which is a slic3r fork) (previously Slic3r++)

Prebuilt Windows, Linux and macOS 64-bit releases are available through the git releases page. The Linux & macOS builds aren't tested (by me), just compiled, so please report any bugs that may occur during use.
For installers, check the badges above. Windows users can use chocolatey or scoop.
Nightly builds are available through the git actions page. Click on the build for your platform and then on the archive name (nightly_win64 or SuperSlicer-gtk2.AppImage or nightly_macos.dmg) in the "Artifacts" section in the top right corner.

SuperSlicer takes 3D models (STL, OBJ, AMF) and converts them into G-code instructions for FFF printers or PNG layers for mSLA 3D printers. It's compatible with any modern printer based on the RepRap toolchain which is running a firmware based on Marlin, Prusa, Klipper, etc.

SuperSlicer is based on PrusaSlicer by Prusa Research. PrusaSlicer is based on Slic3r by Alessandro Ranellucci and the RepRap community.

Development

What language is it written in?

Almost everything is written in C++.

The slicing core is the libslic3r library, which can be built and used in a standalone way. The command-line interface is a thin wrapper over libslic3r. You can download a precompiled package from the release page - it will run without the need for any dependency.

How to compile

If you want to compile the source yourself, follow the instructions on one of these documentation pages:

You can also look at the workflow YAML-files for git actions, as they describe how to build from source from a "virgin" dev computer.
