Why buy each?

Elegoo Centauri Carbon 2

Elegoo's first multicolor FDM

The Centauri Carbon 2 marks Elegoo's entry into multicolor FDM printing — bringing the brand's value-focused approach to a segment dominated by Bambu and Anycubic.

350°C nozzle for engineering filaments

The high-temperature nozzle enables printing of PA, PA-CF, and PC on an open-frame CoreXY — a notable differentiator at this price point.

CANVAS 4-color multicolor system

Elegoo's proprietary CANVAS system provides 4-color filament switching at a competitive all-in price of $449.

Qidi Tech Plus4

305×305×280 mm build volume

One of the largest build volumes in the prosumer enclosed category — 40% more printable area than the Bambu X1C at a lower price point.

Active 65°C chamber heating

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.

370°C bimetal hotend

Handles high-performance engineering composites including PA-CF, PET-CF, and PPS-CF without requiring a separate hotend upgrade.
