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.

Best for: Professional makers, small studios, and engineers who need dual-material printing — particularly for PVA soluble supports, dual-color engineering parts, or high-throughput production.

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 H2S adds better high-speed cooling and more consistent layer adhesion at 600 mm/s, addressing key H2D pain points.
Dual-nozzle printing eliminates the purge tower required by filament-switching systems — faster prints, less wasted filament.
Print PLA + PVA or ABS + HIPS combinations for complex geometries that would be impossible with a single material.
