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 Q2 actively heats the print chamber — not just passively traps heat. This is the key differentiator for reliable ABS, ASA, PA-CF, and PC printing without warping.
Triple-stage filtration removes 99.5% of particulates and VOCs — essential for printing ABS and ASA in a home or office environment.
Handles the full spectrum of engineering filaments including carbon and glass fiber composites without a hotend upgrade.
