Why buy each?

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.

Qidi Tech Q2

Active 65°C chamber heating

The Q2 actively heats the print chamber — not just passively traps heat. This is the key differentiator for reliable ABS, ASA, PA-CF, and PC printing without warping.

HEPA 13 + activated carbon filtration

Triple-stage filtration removes 99.5% of particulates and VOCs — essential for printing ABS and ASA in a home or office environment.

370°C bimetal hotend

Handles the full spectrum of engineering filaments including carbon and glass fiber composites without a hotend upgrade.
