The AD5X undercuts comparable multicolor setups on price with IFS built directly into the printer — no separate accessory needed.
No cloud dependency or mandatory account. OrcaSlicer is community-standard open-source slicer software — familiar to most experienced makers.
Ships ready for PLA-CF and PETG-CF without requiring a nozzle upgrade — a genuine differentiator at this price point.
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.
