MK4 and MK3.5 owners can upgrade to MK4S specs without purchasing a whole new printer. This is Prusa's commitment to owners and is unique in the industry at this level.
Firmware, PCB schematics, hardware designs, and slicing profiles are all published under open licenses. You own the printer completely.
Prusa's forum, knowledge base, and repair guides are unmatched. Parts are stocked and available for years after purchase.
The P2S enclosure maintains a more consistent chamber temperature over the P1S, reducing warping on long ABS and PA prints.
PLA through PC — the P2S handles the entire engineering filament spectrum with reliable results.
The P-series CoreXY enclosure design strikes the best balance of price, speed, and material capability in Bambu's lineup.
