The Prusa MK4 (Prusa) has a direct-drive extruder, an all-metal hotend, with a 290°C max hotend and 120°C max bed (250 × 210 × 220 mm). Of 14 common filaments, 9 are a great match on this hardware out of the box.
What filaments does the Prusa MK4 support? The Prusa MK4 supports 9 filaments out of the box and can handle 5 more with tweaks (usually an enclosure or slower speed). Its all-metal hotend, direct-drive extruder and 120°C bed decide what it can run.

FAQ
What filaments does the Prusa MK4 support?
Can the Prusa MK4 print PETG?
Yes. PETG prints well on the Prusa MK4 at about 240°C hotend and 80°C bed. See the full Prusa MK4 PETG profile.
Can the Prusa MK4 print ABS or ASA?
The Prusa MK4 is open-frame, so ABS and ASA are possible but will warp on larger parts without an enclosure or draft shield. The hotend can reach the temperatures needed.
Does the Prusa MK4 need an all-metal hotend for high-temp filament?
No — the Prusa MK4 already has an all-metal hotend, so it can safely reach the temperatures needed for ABS, ASA, PC and nylon (within its 290°C limit).
