IceSL vs SuperSlicer

IceSL is a free set of 3D modeling and slicing tools for customizable shape fabrication. IceSL-forge combines modeling and slicing through a Lua language that describes Boolean combinations of triangle meshes, voxels, implicit surfaces and shaders. IceSL-slicer turns models or geometry scripts into G-code, DLP printer images and laser-cutter paths. SliceCrafter provides browser-based slicing, while WebPrinter previews G-code by emulating a 3D printer. Available slicing methods include cubic and tetrahedral infills, bridge supports, adaptive layer thickness, progressive infills, efficient offsetting, protective shields and self-supporting cavities. Polyfoam and Phasor infillers expose local density, orientation, direction and randomness controls. Layer thickness, infill density and printing speed can vary by layer. Documentation covers plugins, printer profiles and pyicesl Python bindings. IceSL requires a GPU with full OpenGL 4.3 support. Its free license is limited to internal research and academic use; commercial and production use are forbidden.

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.
