KISSlicer vs SuperSlicer

KISSlicer turns STL files into printer-ready G-code and is a slicer, not a printer control app. Four Profile Wizards help configure printer, material, style, and support settings. Automatic support generation, resin slicing, and variable layer height are supported. The free plan costs nothing and allows multi-extruder printers to be used, but only one extruder can be selected for a print. Pro costs $42, paid once and enables multi-material printing, with extruders assignable to the raft, support, model, and sub-meshes. Premium costs $82, paid once and includes Pro functionality alongside listed features such as colorized meshes, texturing, dynamic density and gyroid infill, warp compensation, and curved surfaces. Profiles can be shared, and Project Files can archive print settings. The software supports Windows, macOS, and Linux; downloads are also listed for FreeBSD and Raspberry Pi. Its license permits commercial use and installation on multiple personal computers, with no time or model-size limit, and prohibits reverse engineering.

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.
