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 V2 expands to 255×255×260 mm — 34% more printable volume than the original Kobra 3 — for larger parts and more batch production.
The V2 includes a 720p camera for real-time print monitoring and AI spaghetti detection, adding reliability features previously absent from the Kobra 3 line.
The Kobra 3 V2 Combo with ACE Pro is one of the most affordable 4-color setups available — often underpricing Bambu's A1 Combo.
