The H2S offers 220% the print volume of the X1C. At 1000 mm/s it is also Bambu's fastest printer, making it the top choice for high-throughput professional production.
The enclosed chamber with active heating handles the full engineering filament spectrum — ABS, ASA, PA, PA-CF, PC, and PPS — with consistent results across the full build plate.
The H2S supports up to 12 AMS units (4 AMS 2 Pro + 8 AMS HT), enabling 24-filament printing for large-format multicolor production.
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.
