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 KE brings CoreXY motion to the Ender 3 family — historically a bed-slinger platform — delivering 500 mm/s without the Bambu premium.
The Ender 3 series has one of the largest 3D printer communities in the world, with thousands of documented modifications and upgrades.
If you outgrow the KE, the Creality K1C and K2 Plus are natural next steps within the same brand ecosystem.
