KISSlicer is a powerful, easy-to-use,
​and fast cross-platform tool that slices
STL files into printer-ready G-code files.​​

Keep It Simple Slicer - KISS!

• Free uses a single extruder for all functions
• Pro unlocks multi-extruder prints for prosumers
• ​Premium unlocks advanced features

KISSlicer incorporates many advanced (but easy to use) slicing features, generating high quality G-code paths for exceptional prints.

​Download and use the FREE version and see for yourself!

Use the Profile Wizards to quickly set up your printer and materials or download profiles shared by the helpful users on the forum. You can still use the FREE version of KISSlicer with a multi-extruder printer, but you are limited to selecting a single extruder for each print.
