Choose the Bambu Lab P2S Combo if you want the more capable multicolor system: its AMS 2 Pro dries filament, the printer can grow to 20 filament slots, and the camera records 1080p. Choose the Elegoo Centauri Carbon 2 Combo if a 350 °C nozzle ceiling and a local-first workflow matter more and four colors are enough. Both are enclosed 256 mm CoreXY printers with a four-filament system in the box, and neither lists an actively heated chamber.

Every figure here comes from Elegoo’s and Bambu Lab’s own pages and wikis, checked October 19, 2026. Speed, noise and flow numbers are each maker’s claims, not measurements. For a standalone look at each machine, see our Centauri Carbon 2 Combo review and the AMS 2 Pro review .

Multicolor: CANVAS vs AMS 2 Pro

Both packages include everything needed to print in four colors, and both feed one nozzle, so a color change means swapping and purging filament rather than switching toolheads. We found no matched waste figure from either maker, so treat any claim about which wastes less as unverified.

The differences are in what surrounds the four slots:

  • Drying. Bambu describes the AMS 2 Pro as a drying unit with an active venting system, and says the P2S can supply power for drying one AMS 2 Pro when the printer is idle. A second unit, or drying during a print, needs Bambu’s separate power adapter, which the Combo does not include. Elegoo’s CANVAS materials describe RFID recognition, auto-refill and tangle detection, not drying. Our AMS vs filament dryer guide covers the stand-alone dryer route.
  • Growth. Bambu says the P2S supports up to 4 AMS 2 Pro and 4 AMS HT units at once, 20 slots in all. The Elegoo pages we checked describe one four-filament CANVAS.
  • TPU. Bambu lists TPU among the P2S’s supported filaments. Elegoo’s wiki has a separate guide for installing a TPU adapter to print TPU on CANVAS models, so soft filament takes an extra step on the Elegoo.
  • Spool fit and space. The Elegoo review we link above notes that the Combo spool holders fit spool bores of 53 to 58 mm, and that the four side spools and tubes need bench clearance. Measure third-party spools before assuming they fit either system.

Nozzle temperature and abrasive filament

Elegoo lists a 350 °C maximum nozzle temperature for the whole Centauri Carbon 2 series, and Bambu lists 300 °C for the P2S. Both ship with a hardened steel nozzle, and the P2S spec sheet lists carbon- and glass-fiber filaments including PLA-CF, PETG-CF, ABS-GF, ASA-CF, PA6-CF, PAHT-CF, PPA-CF and PET-CF. For most hobby work 300 °C is enough headroom. The extra 50 °C on the Elegoo matters mainly if a filament maker’s profile calls for a nozzle temperature above 300 °C, and even then the chamber, bed and drying still decide whether it prints well.

Speed, chamber and noise claims

Bambu lists 600 mm/s and 20,000 mm/s² for the P2S, and Elegoo lists 500 mm/s for the Centauri Carbon 2 series. Those are top motion figures, not print-time forecasts, and neither maker’s spec page publishes a matched benchmark job.

Both machines are enclosed and neither lists active chamber heating. Elegoo adds a chamber thermistor to the Carbon 2 models. Bambu markets the P2S as “50°C chamber ready,” which describes heat retention. Elegoo states printing under 45 dB and Bambu says the P2S has no exhaust fan and is quieter than the P1S, but neither claim is a measurement. See our enclosed printer fume-control guide before putting either in a living space.

Camera, software and ecosystem

The P2S camera records 1920 × 1080 at 30 fps, and the printer has a 5-inch 854 × 480 touchscreen, an 8 GB eMMC and a USB port. Elegoo includes a camera and lighting with the Combo, but the pages checked don’t list its resolution.

On software, the P2S uses Bambu Studio, the Bambu app and the MakerWorld model library, and Bambu says third-party slicers that export standard G-code also work, with some advanced features unavailable. The Elegoo is built around Elegoo Slicer, the Matrix app and a NEX Print model hub. The independent testing summarized in our Centauri Carbon 2 Combo review reports practical LAN and non-cloud operation, which suits buyers who prefer to keep the printer off a vendor cloud.

Watch the model names

Elegoo sells four closely related Centauri 2 models, and the names are easy to confuse. Its own comparison table lists:

  • Centauri 2: CANVAS, camera, lighting, enclosure and chamber thermistor are all optional add-ons.
  • Centauri 2 Combo: CANVAS included; camera, lighting, enclosure and chamber thermistor are optional.
  • Centauri Carbon 2: enclosure, camera, lighting and chamber thermistor included; CANVAS optional.
  • Centauri Carbon 2 Combo: all of them included.

Only the last one is comparable to the P2S Combo. Bambu also sells the P2S without the AMS, so check that a listing says “Combo” before you assume the color system is included.

Which should you buy?

Choose the Bambu Lab P2S Combo if:

  • you want filament drying built into the color system
  • you may want more than four colors or more than one material unit later
  • remote monitoring matters and you want a 1080p camera
  • you want the faster rated motion and the larger Bambu model and accessory ecosystem

Choose the Elegoo Centauri Carbon 2 Combo (search link) if:

  • a 350 °C nozzle ceiling is a requirement for filaments you already plan to use
  • four colors are enough and you would dry filament separately
  • you prefer a local-network workflow over a vendor cloud
  • you have bench room for the four side spools and tubes

When we checked on October 19, 2026, the Amazon listing this site tracks for the Elegoo Combo showed as currently unavailable, so confirm stock on Amazon or at Elegoo’s US store before you plan around it.

FAQ

Which is better for multicolor printing, the Centauri Carbon 2 Combo or the P2S Combo?

On the spec sheets, the P2S Combo has the more capable color system. Its AMS 2 Pro dries filament and the printer supports up to 20 filament slots, while the Centauri Carbon 2 Combo ships with a four-filament CANVAS unit. If four colors and a higher nozzle temperature matter more than drying, the Elegoo is the alternative.

Does the Centauri Carbon 2 Combo have a higher nozzle temperature than the P2S?

Yes. Elegoo lists a 350 °C maximum nozzle temperature, and Bambu lists 300 °C for the P2S. Both bed ceilings are 110 °C, and both printers use a hardened steel nozzle.

Is the Elegoo Centauri 2 Combo the same as the Centauri Carbon 2 Combo?

No. Elegoo’s own model comparison lists the Centauri 2 Combo with CANVAS but with the camera, lighting, enclosure and chamber thermistor as optional add-ons. The Centauri Carbon 2 Combo includes all of them.

Does either printer have a heated chamber?

Neither maker lists active chamber heating. Both printers are enclosed, and Bambu describes the P2S as chamber-heat retaining rather than actively heated.
