Yes, but it takes extra gear or care. The MK4 with a high-flow brass nozzle. Same open frame, faster prints.
PA12 (Nylon 12) is tricky on the Prusa MK4S
No enclosure on this printerPrinter
The Prusa MK4S is open to the room, and PA12 (Nylon 12) warps and cracks in open air. Small parts can survive; for anything bigger, add an enclosure (even a grow tent or a box over the printer helps).
Keep the spool dryMaterial
PA12 (Nylon 12) soaks up moisture from the air, and damp filament prints rough and stringy. If that happens, dry the spool at 70-90 °C for 12-16 h and store it sealed with desiccant.
Buying the CF version of PA12 (Nylon 12)?
Carbon-fiber filament sands down the Prusa MK4S’s stock nozzle. Plain PA12 (Nylon 12) is fine; for the CF variant, fit a hardened steel nozzle first (a cheap swap).
