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.
Unlike most budget enclosed printers that passively trap heat, the K2 Pro actively heats the chamber to 60°C — critical for reliable ABS, ASA, and PA-CF layer adhesion.
The K2 Pro's cubic build volume gives you 50% more printable space than the Bambu X1C (256×256×256 mm) — ideal for large functional parts and prototypes.
The Combo version includes Creality's CFS (Creality Filament System) for 4-color filament switching. Works across the Creality K-series lineup.
