What it is

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.
