Spec score 7.5 #20 of 27 in 3D Slicer Software

What it is

SuperSlicer is a free 3D-printing slicer for Linux, macOS, and Windows. It converts STL, OBJ, AMF, or 3MF models into G-code for FFF printers or PNG layers for mSLA printers. The project describes compatibility with modern RepRap-toolchain printers and firmware based on Marlin, Prusa, Klipper, and others. It is a personal fork of PrusaSlicer, which itself comes from Slic3r, and uses the GNU Affero General Public License version 3. Print preparation controls cover top-surface quality, infill density, thin walls, hole dimensions, overhangs, brims, and seams. Multiple extruders, separately configured objects, variable layer heights, and varied infill patterns are supported. Generated calibration tests and built-in calibration prints help with tuning. A command-line interface works without the graphical interface, while macros and post-processing scripts extend G-code handling. Prebuilt 64-bit releases and nightly builds are listed; the maintainer says Linux and macOS builds were compiled but not tested.

Strong points and limits

Strong points

  • Supports FFF G-code and mSLA PNG output
  • Runs on Windows, macOS, and Linux
  • Includes calibration tests and built-in prints
  • Offers multi-extruder and variable-layer controls
  • Provides command-line and post-processing options

Limits

  • Linux and macOS builds were not maintainer-tested
  • Version 2.7.63.0 beta 2 is a pre-release
  • No paid support or product price is listed

Who it suits

It suits 3D-printing users who need FFF or mSLA output and detailed print controls. It also fits users who want command-line operation or multi-material and variable-height printing.

Verdict

SuperSlicer combines broad printer-output support with extensive tuning controls and calibration tools. Its untested Linux and macOS builds and beta release status are important considerations.
