First-generation product — recently released, still early days
Best for: Professional makers and small studios who need the maximum enclosed build volume in Qidi's lineup for large engineering parts, architectural models, or batch production — at a price point below the Bambu H2S.

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.

The Max4 offers the largest build volume in Qidi's lineup — enabling large functional parts, architectural models, and production batch runs that exceed Plus4 capacity.
The Max4's closed-loop XY adds positional feedback for improved accuracy at high speeds — a differentiating feature at this price tier that reduces dimensional errors on large prints.
Qidi's proven active chamber heating technology scaled to a 390×390 mm bed — critical for consistent ABS, ASA, PA-CF, and PPS-CF results across the full build plate.
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.
