Why consider it?

A die-cast aluminum CoreXY frame, a speed advertised up to 500 mm/s with 10,000 mm/s² acceleration by default, a hardened nozzle up to 350°C, and a 110°C bed per Elegoo.

What to verify

An open frame with no cover, less suited to filaments that need a stable ambient temperature. The CANVAS module for multicolor remains a separate accessory to confirm on the retailer's listing.

The specifications that matter

Process: FDM
Nominal build volume: 256 × 256 × 256 mm
Enclosure: Open frame
Multicolor: The base machine is monochrome; the CANVAS module for 4-color printing is sold separately from the standalone machine.
Materials: PLA and PETG per Elegoo's listing; the open frame is not designed for ABS without an added enclosure.

Allow room for supports and the chosen orientation. Confirm the exact nozzle, feeder, included accessories and installation clearance against the manual and seller’s listing.

Which projects is it for?

The Centauri 2 carries an open-frame CoreXY architecture with a nominal build volume of 256 × 256 × 256 mm per Elegoo, a plate size that suits medium to large parts without aiming for the largest formats.

The advertised speed reaches 500 mm/s at its peak, with 250 mm/s recommended for daily use and a default acceleration of 10,000 mm/s² per Elegoo, targeting users who want shorter print times without moving up a machine tier.

Materials and setup

The hardened 0.4 mm nozzle heats up to 350°C and the bed up to 110°C per Elegoo, values that cover PLA and PETG under good conditions. Since the frame is open, ABS or ASA remain trickier without an added enclosure.

The base machine stays monochrome: Elegoo reserves 4-color printing for the CANVAS module, a separate accessory rather than standard equipment on the Centauri 2.

What the bundle includes or not

Elegoo's listing separates the standalone Centauri 2 from the "Centauri 2 Combo," which pairs the machine with the CANVAS unit for multicolor. The exact box contents (cables, calibration plate, sample filament) should still be checked on the chosen retailer's listing.

Elegoo highlights the die-cast aluminum frame for overall rigidity, a point that matters at the speeds this model advertises.

Alternatives to compare

For multicolor built in from the start rather than as a separate accessory, the same lineup's Centauri Carbon and Centauri Carbon 2 cover an enclosed setup. For a compact, affordable base, the Neptune 4 stays simpler.

The FDM vs. resin guide helps confirm FDM is the right fit for the project before comparing CoreXY machines against each other.

Frequently asked questions

Is the CANVAS module included with the Centauri 2?

No, per Elegoo the base machine is monochrome and the CANVAS module for 4-color printing is sold separately, or in a "Combo" pack distinct from the standalone machine.

Can the Centauri 2 print ABS?

The frame is open per Elegoo, with no stock cover, which makes ABS trickier to stabilize than on an enclosed model. PLA and PETG remain the best-suited materials as shipped.

What speed can you realistically expect?

Elegoo advertises 500 mm/s at its peak but recommends 250 mm/s for everyday use, with a default acceleration of 10,000 mm/s². Actual speed then depends on the filament and the model being printed.
