Just released — full support runway ahead
Best for: Professional makers who want the X1C's footprint with true dual-material capability, an active heated chamber for engineering filaments, and improved filtration — without stepping up to the larger, pricier H2 series.
Full details →Overdue for a refresh — no successor announced yet. Prices should be at their lowest
Best for: Budget-conscious makers who want a capable CoreXY with Klipper firmware for customization — without Bambu's closed ecosystem or Prusa's premium pricing.

A second Bowden-fed nozzle enables two-material prints and soluble supports without a purge tower, in the same compact 256 mm class as the X1C it replaces.
Unlike the X1C's passive chamber warming, the X2D actively heats to 65°C — enough for the bulk of engineering filaments including ABS, ASA, and nylon.
Improved filtration and a toolhead-mounted camera add safety and monitoring over the X1C's chamber camera.
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.
