What SuperSlicer is

SuperSlicer converts 3D model files into G-code for FFF printers or PNG layers for mSLA printers. It accepts STL, OBJ, AMF, and 3MF inputs and is available for Windows, macOS, and Linux. The project describes compatibility with modern printers using the RepRap toolchain and firmware based on Marlin, Prusa, Klipper, and others. Print-preparation controls cover surfaces, infill, thin walls, hole dimensions, overhangs, brims, and seams. It supports multiple extruders, objects with distinct settings, variable layer heights, and multiple infill patterns. Calibration tests and built-in prints are included. Users can work through a command-line interface without the graphical interface, and customize G-code macros and post-processing scripts. SuperSlicer is a free personal fork of PrusaSlicer, which is based on Slic3r, and is licensed under GNU AGPL version 3. Prebuilt 64-bit releases and nightly builds are listed. The maintainer says Linux and macOS builds have been compiled but not tested.

Who it suits

SuperSlicer suits people preparing prints for FFF or mSLA printers who need model slicing and print-tuning controls. Its command-line interface may suit users who want to work without the graphical interface.

What it does well

Getting started

  1. Open the SuperSlicer GitHub project
  2. Download the prebuilt release for Windows, Linux, or macOS
  3. Import an STL, OBJ, AMF, or 3MF model
  4. Select settings for the target printer and material
  5. Run calibration tests or built-in calibration prints
  6. Generate G-code or PNG layers

Verdict

SuperSlicer combines broad print-preparation controls with both graphical and command-line use. Note the maintainer's caveat that Linux and macOS builds were compiled but not tested.
