Bambu's largest bed-slinger build volume, big enough to print full-size helmets and large props in a single piece rather than in glued sections.
The A2L stores several calibration sets at different heights up the Z axis to keep the faint vertical banding of tall bed-slinger prints under control.
An add-on blade-cutting and pen module extends the A2L beyond printing for sticker cutting and plotting workflows.
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.
