The X1C's LiDAR sensor maps bed surface deviation and adjusts in real time — the most reliable first-layer consistency in its class.
The built-in camera with spaghetti detection pauses prints automatically when failures are detected — critical for unattended production runs.
The X1C uses a die-cast metal frame and carbon-fiber-reinforced structure for rigidity at high speeds.
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.
