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.
At $279–299 with ACE Gen 2 included, the Kobra X is one of the most affordable ways to get into multicolor FDM printing.
A slightly larger cube-format build volume than the Kobra 3 V2's 255×255×260 mm bed — practical for most everyday prints.
The second-generation ACE Gen 2 offers improved filament switching reliability over the original ACE Pro, with support for up to 4 colors per print.
