The Bambu Lab P1S (prosumer) and Elegoo Centauri 2 (entry) 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 Note that the P1S has been replaced by the P2S and is no longer sold new. Both are CoreXY printers with 4-slot multicolor, a 500 mm/s rated top speed and automatic calibration. The P1S costs $250 more and gets you an enclosed chamber (with ABS, ASA, PA, PA-CF and PC on its materials list); the Centauri 2 answers with support for PLA-CF and PETG-CF.
This printer is no longer sold new. It has been replaced by the Bambu Lab P2S.
Best for: Makers who need an enclosed printer for ABS, ASA, PA, and PC at prosumer price — now available at clearance pricing after P2S launch.

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.

The P1S has been replaced by the P2S and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.
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.
On timing alone, the Centauri 2 is the safer buy right now — it launched only 141 days ago, while the P1S has already been replaced by the P2S.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Centauri 2 lists at $299 and the P1S at $549 — $250 apart, so the P1S costs 84% more.
Per litre of build volume, that works out to $33 for the P1S versus $18 for the Centauri 2 — the Centauri 2 is the better value per litre as well.
Buy the Centauri 2. The P1S has already been replaced by the P2S and is no longer sold new, so it is only worth considering at a clearance price. If the P1S appealed to you, the fair comparison today is the Centauri 2 against the P2S.

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.
