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.
All firmware, hardware designs, and slicing profiles are open source. Prusa backs the CORE One L+ with long-term parts availability and community support.
For institutional, government, and production customers, a dedicated Critical Infrastructure Edition is offered — Prusa's commitment to secure supply for professional users.
The Max4 offers the largest build volume in Qidi's lineup — enabling large functional parts, architectural models, and production batch runs that exceed Plus5 capacity.
The Max4's closed-loop XY adds positional feedback for improved accuracy at high speeds — a differentiating feature at this price tier that reduces dimensional errors on large prints.
Qidi's proven active chamber heating technology scaled to a 390×390 mm bed — critical for consistent ABS, ASA, PA-CF, and PPS-CF results across the full build plate.
