💡About the Prusa Research Core One

The Prusa Core One is Prusa Research's first CoreXY 3D printer, launched January 2025. It brings the speed and precision of CoreXY motion to Prusa's open-source ecosystem, targeting the same prosumer audience as Bambu's P-series but with full open-source firmware and hardware. At 600 mm/s, it is Prusa's fastest printer to date.

  • Prusa's answer to Bambu P-series

    The Core One matches Bambu CoreXY speed (600 mm/s) while keeping everything open source — firmware, hardware, slicing profiles.

  • Fully open source

    Unlike Bambu's closed ecosystem, every component of the Core One can be modified, repaired, or community-improved.

  • MMU3 multicolor compatible

    Existing MMU3 units and the new MMU3 for Core One bring 5-color multicolor printing to the CoreXY platform.

🎯Who is this 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.

FAQs

Prusa Core One vs Bambu P2S — which should I choose?

The defining choice is ecosystem philosophy. Bambu offers a polished closed ecosystem with faster setup, proprietary cloud features, and an aggressive innovation cadence. Prusa offers open-source hardware, longer product lifecycles, community repairability, and no lock-in. If you plan to modify, repair, or build on the printer, Prusa. If you want the fastest out-of-box experience, Bambu.

Does the Core One need an enclosure for engineering filaments?

Like the Bambu P1S and P2S, the Core One is an open-frame CoreXY. It handles PLA, PETG, and TPU well. For ABS and ASA, an aftermarket enclosure is recommended. A factory-enclosed Core One S is rumoured for 2027.

Is the Core One kit worth building?

Yes — the kit is significantly cheaper than the assembled version and gives you deep familiarity with your printer's components, making maintenance and troubleshooting easier.
