Why consider it?
A 390 × 390 × 340 mm volume in an enclosed chassis, an active 65°C heated chamber, a nozzle advertised up to 370°C, a speed advertised up to 800 mm/s, and an AI camera per QIDI.
What to verify
Multi-material or multicolor printing runs through the separately sold QIDI Box module. Some accessories like the Polar Cooler ship separately per QIDI; check the exact contents on the retailer's listing.
The specifications that matter
- Process
- FDM
- Nominal build volume
- 390 × 390 × 340 mm
- Enclosure
- Enclosed
- Multicolor
- No stock multicolor system; compatible with the separately sold QIDI Box module for multi-material printing.
- Materials
- PLA, PETG, ABS, ASA, TPU, PA, PC, PPS-CF, and other carbon-fiber composites per QIDI, thanks to a 370°C nozzle.
Allow room for supports and the chosen orientation. Confirm the exact nozzle, feeder, included accessories and installation clearance against the manual and seller’s listing.
Which projects is it for?
The Max4 targets enclosed large-format printing with a nominal build volume of 390 × 390 × 340 mm per QIDI, presented by the manufacturer as a 55% step up from the Max3. It suits bulky parts, multiple batches, or projects that outgrow a standard desktop machine.
A speed advertised up to 800 mm/s with 30,000 mm/s² acceleration per QIDI keeps print time reasonable despite the large area to cover on each layer.
Materials and setup
A nozzle advertised up to 370°C and a chamber actively heated to 65°C per QIDI cover a wide range of engineering filaments: PLA, PETG, ABS, ASA, TPU, PA, PC, and PPS-CF, plus other carbon-fiber composites.
A closed-loop XY motor system with encoder feedback is advertised by QIDI to correct step loss, useful on a bed this size where deviations are more visible.
What the bundle includes or not
A real-time AI monitoring camera and three-stage filtration (HEPA and activated carbon) are advertised as built in by QIDI. The QIDI Box module for multicolor or multi-material printing remains a separate accessory, not included on the base machine.
QIDI notes that some accessories, like the Polar Cooler, may ship separately from the machine; the exact box contents should still be checked on the chosen retailer's listing.
Alternatives to compare
For a more compact enclosed format from the same brand, the Q1 Pro stays a more accessible base. For an already proven large format, the X-Max 3 covers a smaller volume in a similar lineup.
The startup budget tool helps weigh the cost of a machine this size against add-ons like the QIDI Box.
