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.

Elegoo Neptune 4 Pro

Klipper firmware out of the box

The Neptune 4 Pro ships with Klipper pre-installed — enabling advanced input shaping, pressure advance, and configuration flexibility without modding.

500 mm/s at budget pricing

Competitive CoreXY speed at a price significantly below Bambu and Prusa alternatives.

Auto calibration

Full automatic bed leveling reduces setup time and calibration friction.
