What filament can the Prusa i3 MK3 print?
A guide to the materials the Prusa i3 MK3 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) | With care | On the edge - PC really wants an enclosed, hot chamber to avoid warping. |
| 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. |
