Buy/Wait:Wait

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.

Flashforge AD5X
Buy/Wait:Buy

First-generation product — recently released, still early days

Best for: Budget-conscious makers who want built-in 4-color multicolor printing under $400 — primarily for PLA and PETG. Open frame, so not suited for ABS or engineering filaments without the add-on enclosure.

Why buy each?

Elegoo Neptune 4 Pro

Klipper firmware out of the box

The Neptune 4 Pro ships with Klipper pre-installed — enabling advanced input shaping, pressure advance, and configuration flexibility without modding.

500 mm/s at budget pricing

Competitive CoreXY speed at a price significantly below Bambu and Prusa alternatives.

Auto calibration

Full automatic bed leveling reduces setup time and calibration friction.

Flashforge AD5X

Built-in 4-color multicolor at $399

The AD5X undercuts comparable multicolor setups on price with IFS built directly into the printer — no separate accessory needed.

OrcaSlicer with local-only control

No cloud dependency or mandatory account. OrcaSlicer is community-standard open-source slicer software — familiar to most experienced makers.

Hardened steel nozzle as standard

Ships ready for PLA-CF and PETG-CF without requiring a nozzle upgrade — a genuine differentiator at this price point.
