Other Compatible Slicers
Note: Many other excellent slicing software options exist, including Cura, Simplify3D, ideaMaker, KISSlicer, and others. While we don't currently track profiles for these slicers in our database, they may work perfectly with your Prusa MK4S. Check each slicer's official documentation or community forums for compatible profiles and settings. You can also contribute profiles to our open-source slicer profile database on GitHub.
What filament can the Prusa MK4S print?
A guide to the materials the Prusa MK4S can handle, based on its hotend, heated bed specs.
| Filament | Suitability | Notes |
|---|---|---|
| PLA | Great | The easiest filament to print. Works on almost any printer; a heated bed helps adhesion but is not required. |
| PETG | Great | Comfortably in range (PETG likes a ~230-250C hotend and a ~70-85C bed). |
| TPU & flexibles | Great | The direct-drive extruder feeds flexible filament well. Print slowly for clean results. |
| ABS & ASA | Great | The high-temperature hotend and hot bed handle ABS and ASA well. An enclosure helps further on large parts. |
| Nylon (PA) | Good | Doable with care - dry the filament thoroughly, and an enclosure helps a lot. |
| Polycarbonate (PC) | Good | In range for PC. Dry the filament, print slowly, and use an enclosure for the best results. |
| Carbon-fiber & glass-filled | With care | Possible if you fit a hardened or wear-resistant nozzle - the abrasive fibers quickly wear a stock brass nozzle. |
