A large enclosed build volume with genuine active chamber heating — making the CORE One L reliable for ABS, ASA, PA, and PC across the full build plate.
All firmware, hardware designs, and slicing profiles are open source. Prusa backs the CORE One L with long-term parts availability and community support.
For institutional, government, and production customers, a dedicated Critical Infrastructure Edition is offered — Prusa's commitment to secure supply for professional users.
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.
