SuperSlicer

Q: Oh cool, a new fork of slic3r?

A: Yeah!

Slic3r++

Prebuilt Windows 64b releases are available through the git releases page. Nightly builds for windows, Linux and macos are available through the git actions page. Click on the a build for your plateform and then on 'Artifacts (1)' in the top right corner.

Slic3r++ 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, including all those based on the Marlin, Prusa, Sprinter and Repetier firmware. It also works with Mach3, LinuxCNC and Machinekit controllers.

Slic3r++ is based on Slic3r by Alessandro Ranelucci and the RepRap community.

See the project homepage and the documentation directory for more information.

What language is it written in?

Almost everything are 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.

What are this fork main features/differences?

• Ironing top surface & many new settings to fine-tune the top surface quality, like 'only one perimeter on top'.
• A "denser infill" option for supporting the (solid) top layers.
• Better Thin walls (anchored inside the print, no more random bits at the ends).
• Options to change holes dimensions and/or geometry, to print them at the right size.
• Better overhangs (add perimeters if needed, slice them in opposite direction each layer).
• Brim rework: many more options (inside, outside only, 'ears')
• Some new seam options, to help hide them.
• Can join perimeters into a big one to avoid travel moves.
• Many other little options and corrections (like the filled concentric pattern).
• It has also all the current slic3rPE/PrusaSlicer features.

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 & varying density 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, gyroid
• 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

Development

You can download a precompiled package from the release page. it will run without the need for any dependency.

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

• Linux
• macOS
• Windows

Also, you can look at the worklow yaml files for git actions, as they describe how to build from source from a "virgin" dev computer.

Can I help?

Sure! You can do the following to find things that are available to help with:

• Add an issue to the github tracker if it isn't already present.

Before sending patches and pull requests contact me (preferably through opening a github issue or commenting on an existing, related, issue) to discuss your proposed changes: this way we'll ensure nobody wastes their time and no conflicts arise in development.
