Supported Materials

PLAEasiest to print, great for everyday parts — no enclosure needed
PETGTougher and slightly flexible — good for functional parts, moisture-resistant
ABSHeat and impact resistant — needs enclosure to avoid warping
ASALike ABS but UV-stable — good for outdoor parts, needs enclosure
TPUFlexible and rubber-like — great for phone cases, gaskets, wheels
PANylon — strong and wear-resistant, absorbs moisture, needs dry storage
PA-CFCarbon-fibre nylon — very stiff and lightweight, abrasive to standard nozzles
PCPolycarbonate — extremely tough and heat-resistant, challenging to print

💡About the Prusa Research CORE One L

The Prusa CORE One L is Prusa Research's enclosed large-format CoreXY, featuring a 300×300×330 mm build volume with active 60°C chamber heating for engineering materials. It is also offered in a 'Critical Infrastructure Edition' for institutional and government customers. Fully open source from firmware to hardware designs, it competes directly with the Qidi Plus4 and Creality K2 Pro in the enclosed large-format segment.

  • 300×300×330 mm with active 60°C chamber heating

    A large enclosed build volume with genuine active chamber heating — making the CORE One L reliable for ABS, ASA, PA, and PC across the full build plate.

  • Fully open source

    All firmware, hardware designs, and slicing profiles are open source. Prusa backs the CORE One L with long-term parts availability and community support.

  • Critical Infrastructure Edition available

    For institutional, government, and production customers, a dedicated Critical Infrastructure Edition is offered — Prusa's commitment to secure supply for professional users.

🎯Who is this for?

Engineers and professional makers who need large-format enclosed printing with active chamber heating — and want Prusa's open-source ethos and long-term support over a closed-ecosystem competitor.

FAQs

CORE One L vs Qidi Plus4 — which large enclosed printer should I buy?

The Qidi Plus4 offers a 305×305×280 mm build volume with active 65°C chamber heating at $699 — a strong value proposition. The CORE One L matches or exceeds the build volume with active 60°C heating and adds Prusa's open-source hardware, parts availability, and community. If you value open-source hardware and Prusa's long-term support, the CORE One L. If you want the best value per dollar for enclosed large-format printing, the Plus4 is hard to beat.

CORE One L vs CORE One+ — which Prusa should I choose?

The CORE One+ is an open-frame CoreXY best suited to PLA, PETG, and TPU. The CORE One L adds active chamber heating and an enclosure, enabling reliable ABS, ASA, PA, and PC at a larger 300×300×330 mm build volume. If you regularly print engineering filaments or need the larger build area, the CORE One L. For most PLA/PETG work, the CORE One+ is the better value.

Does Prusa offer multicolor support for the CORE One L?

Yes. The Original Prusa MMU3 for CORE One L is available as an optional add-on kit at prusa3d.com, enabling up to 5-filament multi-material printing. It uses Prusa's innovative retraction technique with a compact wipe tower to minimize filament waste. No upgrade kit from CORE One+ to CORE One L exists — they are different machines (open frame vs enclosed).
