The Prusa Research CORE One L+ (professional) and Qidi Tech Plus4 (prosumer) come from different brands and sit in different tiers, so this is less a head-to-head than a question of how much printer you need. Note that the Plus4 has been replaced by the Plus5 and is no longer sold new. Both are enclosed CoreXY printers with automatic calibration. The CORE One L+ costs $1,300 more and gets you an open-source design and 14% more build volume; the Plus4 answers with 4-slot multicolor and a top speed of 600 mm/s (vs 500).

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The Plus4 has been replaced by the Plus5 and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.
On timing alone, the CORE One L+ is the safer buy right now — it is only 33% of the way through its expected cycle, while the Plus4 has already been replaced by the Plus5.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Plus4 lists at $699 and the CORE One L+ at $1,999 — $1,300 apart, so the CORE One L+ costs 186% more.
Per litre of build volume, that works out to $67 for the CORE One L+ versus $27 for the Plus4 — the Plus4 is the better value per litre as well.
Buy the CORE One L+. The Plus4 has already been replaced by the Plus5 and is no longer sold new, so it is only worth considering at a clearance price. If the Plus4 appealed to you, the fair comparison today is the CORE One L+ against the Plus5.
