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 →Overdue for a refresh — no successor announced yet. Prices should be at their lowest
Best for: Professional makers and small studios who need dual-material printing for engineering parts with soluble supports — or true dual-color without purge waste.

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 H2D prints two materials simultaneously from two nozzles. This eliminates purge tower waste and enables true dual-material prints including PVA/PLA soluble support combinations.
350×320×325 mm gives more print area than the standard 256 mm Bambu models — suited for larger professional parts.
The H2D supports a wide range of engineering filaments including PA-CF, PETG-CF, and PC with its enclosed chamber.
