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 P2S enclosure maintains a more consistent chamber temperature over the P1S, reducing warping on long ABS and PA prints.
PLA through PC — the P2S handles the entire engineering filament spectrum with reliable results.
The P-series CoreXY enclosure design strikes the best balance of price, speed, and material capability in Bambu's lineup.
