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.
Unlike filament-switching AMS/MMU systems, the XL physically swaps print heads. Each material has its own nozzle, eliminating purge towers entirely and enabling true multi-material prints.
One of the largest build volumes available in a CoreXY printer at this price point — suited for large props, architectural models, and batch production.
Every component is documented, parts are stocked for years, and the community has developed hundreds of modifications and improvements.
