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.
One of the largest build volumes available at a consumer price — ideal for life-size props, large terrain tiles, and batch production.
Few printers offer multicolor at this scale. The ACE Pro system enables filament switching across the full 420×420 bed area.
Delivers large-format multicolor at a fraction of professional large-format printer costs.
