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.
One of the largest build volumes in the prosumer enclosed category — 40% more printable area than the Bambu X1C at a lower price point.
The second-generation active heating delivers consistent chamber temperatures for PA, PA-CF, ABS, ASA, and PC with minimal warping across the full build plate.
Handles high-performance engineering composites including PA-CF, PET-CF, and PPS-CF without requiring a separate hotend upgrade.
