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 H2C's Vortek system swaps hotends wirelessly — no filament purging, no switching waste. Each material has its own dedicated nozzle, enabling true multi-material production including soluble support combinations.
With up to 6 active hotends and the Vortek architecture, the H2C supports 7 simultaneous material slots — the highest material count in Bambu's lineup.
At $2,399, the H2C is positioned above the H2S as Bambu's flagship professional tool-changer — targeting studios and engineers who outgrow filament-switching AMS multicolor.
