Overdue for a refresh — no successor announced yet. Prices should be at their lowest
Best for: Professional makers and small studios who need dual-material printing for engineering parts with soluble supports — or true dual-color without purge waste.

The H2D prints two materials simultaneously from two nozzles. This eliminates purge tower waste and enables true dual-material prints including PVA/PLA soluble support combinations.
350×320×325 mm gives more print area than the standard 256 mm Bambu models — suited for larger professional parts.
The H2D supports a wide range of engineering filaments including PA-CF, PETG-CF, and PC with its enclosed chamber.
The Neptune 4 Pro ships with Klipper pre-installed — enabling advanced input shaping, pressure advance, and configuration flexibility without modding.
Competitive CoreXY speed at a price significantly below Bambu and Prusa alternatives.
Full automatic bed leveling reduces setup time and calibration friction.
