How much space does it need?

The Qidi Plus 4 measures 505 × 487 × 550 mm (19.9 × 19.2 × 21.7 in) for a 305 × 305 × 280 mm (12 × 12 × 11 in) build volume: the dashed box is the printer, the solid cube the largest theoretical part, about 19% of the machine’s volume. Add room for the spool or multicolor unit, cables and ventilation.

Which projects is it for?

The Plus 4 is a large-format CoreXY FDM printer, with a 305 × 305 × 280 mm nominal build volume per QIDI. It targets makers who want to print large parts or batch several objects on one plate without giving up an actively heated chamber.

The chamber, heated up to 65°C using a newer generation than the Q1 Pro's per QIDI, helps limit warping on large parts, which are more exposed to drafts than a compact-format print.

Materials and setup

A nozzle advertised up to 370°C and a bed up to 120°C let it print ABS, ASA, PETG, and TPU on top of standard PLA per QIDI, with a default 0.4mm nozzle (0.2/0.6/0.8mm optional).

QIDI also lists compatibility with PA, PC, and glass- or carbon-fiber reinforced composites, materials that directly benefit from the heated chamber at this size.

What the bundle includes or not

Per QIDI, the 5-inch touchscreen, Wi-Fi/Ethernet/USB connectivity, and auto-calibration are part of the standard equipment. The QIDI Box, which adds multicolor, is offered as an option or in a separate combo pack.

The exact box contents (spare nozzles, an extra plate) aren't specified on the manufacturer's listing: check the retailer's page, especially to confirm whether the QIDI Box is included in your chosen offer.

Alternatives to compare

For a more compact format with a comparable heated chamber, the Q2 is the most direct comparison within QIDI's lineup. The Q1 Pro, now discontinued, shows how the lineup evolved toward this Plus 4.

Against other enclosed large formats, the Creality K1 Max offers a similar volume without an actively heated chamber, a useful comparison depending on the materials you target.

Frequently asked questions

What is the build volume of the Qidi Plus 4?

QIDI Tech lists a 305 × 305 × 280 mm (12 × 12 × 11 in) build volume (width × depth × height). That is the largest theoretical part size; supports, brim and orientation reduce the usable space.

How big is the Qidi Plus 4?

According to QIDI Tech, the Qidi Plus 4 measures 505 × 487 × 550 mm (19.9 × 19.2 × 21.7 in) (width × depth × height) and weighs 27 kg (59.5 lb). Leave extra clearance for the spool, cables and airflow, and more if you add a multicolor unit.

How fast is the Qidi Plus 4?

QIDI Tech claims a top toolhead speed of 600 mm/s and 20,000 mm/s² acceleration. Real print times depend on the material, the profile and the part; this is a manufacturer figure, not our measurement.

Is the Qidi Plus 4 enclosed?

Yes, it has an enclosed build chamber with active heating up to 65 °C (149 °F), which helps with ABS and ASA. Its nozzle reaches 370 °C (698 °F) and its bed 120 °C (248 °F).

Is the QIDI Box included with the Plus 4?

No, per QIDI's listing, the QIDI Box that adds multicolor is offered as an option or in a separate combo pack; check the exact listing on the retailer's page before buying.

Is a heated chamber useful for large parts?

Yes: per QIDI, heating the air up to 65°C limits warping on large parts, which are more exposed to drafts than a small part printed on a compact format.

What's the difference from the Q2?

The Plus 4 offers a considerably larger volume (305 × 305 × 280 mm versus 270 × 270 × 256 mm) per QIDI, for bigger parts, with a comparable generation of heated chamber.
