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 'Artifacts (1)' 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.
See the wiki and the documentation directory for information about compilation.
- Custom-made generated calibration tests.
- 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, embedded in perimeter loops).
- 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', per object)
- Some new seam options, to help hide them.
- Built-in calibration prints
- Built-in object generation script
- 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.
Complete changelog here
See the wiki for examples.
Key features are:
- Multi-platform (Linux/Mac/Win) and packaged as standalone-app with no dependencies required
- Complete command-line interface to use it without 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 adjustment of speed, acceleration, and 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
Command-Line Interface wiki page.
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.
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.
