The Kobra S1 combines an enclosed build chamber with 600 mm/s CoreXY motion — offering improved heat retention over open-frame printers for ABS and ASA.
Brings Anycubic's value-focused approach to the enclosed CoreXY segment — competing with Qidi Q2C and Bambu P2S at a lower price point.
A practical cubic build volume well-suited for functional mechanical parts, enclosures, and prototypes.
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.
