Mid-cycle — watch for announcements before buying
Best for: Makers who want CoreXY speed and precision with Prusa's open-source ethos, community support, and long-term repairability — without Bambu's closed ecosystem.
Full details →Late in cycle — a new model is likely coming soon
Best for: Professional makers and small businesses who need the highest level of print monitoring, reliability, and material compatibility in a production-ready package.

The Core One matches Bambu CoreXY speed (600 mm/s) while keeping everything open source — firmware, hardware, slicing profiles.
Unlike Bambu's closed ecosystem, every component of the Core One can be modified, repaired, or community-improved.
Existing MMU3 units and the new MMU3 for Core One bring 5-color multicolor printing to the CoreXY platform.
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.
