The Prusa Research CORE One L+ and Qidi Tech Max4 are both professional-tier printers, but the CORE One L+ costs 1.9× as much — so the question is what the extra money buys. Both are enclosed CoreXY printers with automatic calibration. The CORE One L+ costs $950 more and gets you an open-source design; the Max4 answers with 74% more build volume and a top speed of 800 mm/s (vs 500).
Early in release cycle — no urgency to wait
🔧 Upgrade kit available — from CORE One L
Best 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.

The CORE One L+ was released on Aug 13, 2026, 91 days ago. Its previous release cycle ran about 279 days, so it is 33% of the way through — roughly 188 days before a successor would be due at that pace.
The Max4 was released on Dec 1, 2025, 346 days ago. It is a first-generation product, so there is no earlier cycle to predict its successor from.
Both are early enough in their cycles that timing should not decide this one. The CORE One L+ has roughly 188 days of runway on past cadence and the Max4 launched 346 days ago. Pick on features and price.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Max4 lists at $1,049 and the CORE One L+ at $1,999 — $950 apart, so the CORE One L+ costs 91% more.
Per litre of build volume, that works out to $67 for the CORE One L+ versus $20 for the Max4 — the Max4 is both cheaper and roomier, so it wins on value outright.
If you are buying before Dec 5, 2026, the active sale tips value toward the Max4.
Our pick for most buyers is the Max4, for a lower price ($950 less) and 74% more build volume. Go for the CORE One L+ instead if you want an open-source printer you can modify and repair yourself — the Max4 is not open source. The Max4 is also in a sale window right now (Black Friday 2026, until Dec 5, 2026).

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.
