The Elegoo Centauri 2 (entry) 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 Note that the Plus4 has been replaced by the Plus5 and is no longer sold new.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 CoreXY printers with 4-slot multicolor and automatic calibration. The Plus4 costs $400 more and gets you an enclosed chamber (with ABS, ASA, PA, PA-CF, PC and PPS-CF on its materials list) and 55% more build volume; the Centauri 2 answers with support for PLA-CF and PETG-CF.
First-generation product — recently released, still early days
Best for: Budget buyers who mainly print PLA, PETG and TPU and want fast CoreXY multicolor for as little as possible, without paying for an enclosure they won't use.

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 Centauri 2 was released on Jun 24, 2026, 141 days ago. It is a first-generation product, so there is no earlier cycle to predict its successor from.
The Plus4 has been replaced by the Plus5 and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.
On timing alone, the Centauri 2 is the safer buy right now — it launched only 141 days ago, while the Plus4 has already been replaced by the Plus5.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Centauri 2 lists at $299 and the Plus4 at $699 — $400 apart, so the Plus4 costs 134% more.
Per litre of build volume, that works out to $18 for the Centauri 2 versus $27 for the Plus4 — the Centauri 2 is the better value per litre as well.
Buy the Centauri 2. The Plus4 has already been replaced by the Plus5 and is no longer sold new, so it is only worth considering at a clearance price.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 Centauri 2 against the Plus5.

The Centauri 2 Combo includes the 4-color CANVAS system with RFID filament detection, auto refill and tangle detection. It is one of the cheapest CoreXY multicolor packages from a major brand.
It uses the same 256×256×256 mm CoreXY motion system, 500 mm/s top speed, 350°C hardened nozzle and 121-point auto leveling as the Centauri Carbon 2, for $50–100 less.
The camera, air filter, LED lighting and smart exhaust grill are optional add-ons, so you pay only for the features you need.
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.
