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 H2S adds better high-speed cooling and more consistent layer adhesion at 600 mm/s, addressing key H2D pain points.
Dual-nozzle printing eliminates the purge tower required by filament-switching systems — faster prints, less wasted filament.
Print PLA + PVA or ABS + HIPS combinations for complex geometries that would be impossible with a single material.
