Alternatives to KISSlicer
Fast, compact slicer that converts STL models into G-code for filament printers. The listings below can replace it for an important use case. Each note says what changes if you switch.
The original
KISSlicer
Fast, compact slicer that converts STL models into G-code for filament printers.
Replacements
Listings that take over the same core job as KISSlicer.
UltiMaker Cura
The most widely used free slicer for filament 3D printers, with profiles for hundreds of machines.
UltiMaker Cura is free and open source under LGPL-3.0 with profiles for hundreds of printers, but it is heavier and slower to start than KISSlicer.
PrusaSlicer
Prusa Research's slicer, based on Slic3r, for both filament and resin printers and no account required.
PrusaSlicer is free and open source under AGPL-3.0, handles filament and resin printers, and offers per-layer setting changes and painted supports and seams.
OrcaSlicer
A slicer built around calibration, with temperature towers and flow tests you run from inside the program.
OrcaSlicer is free and open source with built-in calibration tests, but it exposes many more settings, which may feel heavy for straightforward prints.
Bambu Studio
Bambu Lab's slicer, built on PrusaSlicer, with project-based workflows, multi-material painting and remote printer monitoring.
Bambu Studio is free and open source with multi-material painting at no cost, but it is built around Bambu Lab printers and is heavier than PrusaSlicer.
SuperSlicer
A PrusaSlicer fork with extra fine-tuning settings, generated calibration tests and better thin-wall handling.
SuperSlicer is free under AGPL-3.0 with generated calibration prints and fine-grained surface settings, but its extra options make an already dense interface denser.
Simplify3D
Prepare and preview print jobs with a commercial 3D slicer.
Simplify3D is also closed source but fully paid, requiring a license, with configurable slicing processes, support generation and toolpath controls.
ideaMaker
Prepare 3D models for printing with Raise3D's slicer.
ideaMaker is free and closed source, made by Raise3D, with printer profiles and advanced features that depend on supported hardware.
IceSL
Slicer with built-in modelling that turns STL files into printer-ready G-code.
IceSL is free but closed source, adds a scriptable modeller for procedural infill and geometry, and has thinner documentation and printer profiles.
Also worth comparing
These listings name KISSlicer as their own alternative, so the relationship runs both ways.
Creality Print
Creality's official slicer for preparing models and sending prints to its FDM 3D printers.
KISSlicer is a fast, simple, closed-source slicer whose free version is single-extruder only, with multi-extruder and advanced features behind paid Pro or Premium licences.
