The Prusa Research CORE One+ and Qidi Tech Plus4 are cross-brand rivals: both are prosumer-tier printers, listed $300 apart. Note that the Plus4 has been replaced by the Plus5 and is no longer sold new. Both are enclosed CoreXY printers with a 600 mm/s rated top speed and automatic calibration. The CORE One+ costs $300 more and gets you an open-source design and 8 multicolor slots to the Plus4's 4; the Plus4 answers with 75% more build volume and extra engineering materials (PA-CF and PPS-CF).
Early in release cycle — no urgency to wait
🔧 Upgrade kit available — from CORE One+, MK4S
Best 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.

Best for: Makers and small businesses who need a large enclosed build volume for engineering materials at a prosumer price — particularly those printing PA-CF, ABS, and PC at scale. Look for clearance deals — the Plus5 is the current model.

The CORE One+ was released on Aug 13, 2026, 91 days ago. Its previous release cycle ran about 209 days, so it is 44% of the way through — roughly 118 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The Plus4 has been replaced by the Plus5 and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.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One+ is the safer buy right now — it is only 44% of the way through its expected cycle, while the Plus4 has already been replaced by the Plus5.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+ at $999 — $300 apart, so the CORE One+ costs 43% more.
Per litre of build volume, that works out to $67 for the CORE One+ versus $27 for the Plus4 — the Plus4 is both cheaper and roomier, so it wins on value outright.
Buy the CORE One+. The Plus4 has already been replaced by the Plus5 and is no longer sold new, so it is only worth considering at a clearance price.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+ against the Plus5.

How we judge timing and deals: read our methodology →
The CORE One+ matches Bambu CoreXY speed (600 mm/s) while keeping everything open source — firmware, hardware, slicing profiles.
Unlike Bambu's closed ecosystem, every component of the CORE One+ can be modified, repaired, or community-improved.
The CORE One+ (Gen 2) can be ordered with Prusa's INDX toolchanger in 4- or 8-tool versions, shipping from 15 October 2026. Each material gets its own nozzle, with about 12 seconds per material change and almost no purge waste. The MMU3 remains compatible as a 5-color add-on.
One of the largest build volumes in the prosumer enclosed category — 40% more printable area than the Bambu X1C at a lower price point.
The second-generation active heating delivers consistent chamber temperatures for PA, PA-CF, ABS, ASA, and PC with minimal warping across the full build plate.
Handles high-performance engineering composites including PA-CF, PET-CF, and PPS-CF without requiring a separate hotend upgrade.
