Best Filament for the QIDI Plus5
A $749 high-temperature workhorse: third-generation 65 C chamber, 370 C hotend, 40 mm³/s flow and a 320 × 320 × 300 mm box sized for engineering parts.

The QIDI Plus5 is an enclosed printer with a 320 × 320 × 300 mm build volume and a hotend reaching 370°C. It handles ABS, ASA, PC and nylon, and it runs abrasive carbon- and glass-fibre filament on its stock nozzle. It has an actively heated chamber. Recommended materials: PLA, PLA+, PETG, TPU, PLA-CF, PETG-CF, ABS, ASA, PC, Nylon, CF / GF composites.
The Plus5 replaced the Plus4 in August 2026 and added 20 mm in every axis for a 320 × 320 × 300 mm volume in roughly the same footprint. The filament story is the third-generation chamber heater: 65 C of regulated chamber air, a 120 C bed and a 370 C hotend. That combination is aimed squarely at ABS, ASA, PC, PA and PPS-CF, where interlayer shrinkage rather than nozzle temperature is what cracks a part. Tom's Hardware put it plainly after testing, saying the machine was made for PPS, PA and PC, and that running low-temperature filament in it feels like taking a race car shopping.
What the QIDI Plus5 prints well
Recommended materials for this printer:
Enclosed and abrasive-ready out of the box, so it handles the full range from PLA to engineering composites, no nozzle swap needed.
Flow rate is the other upgrade that changes filament choice. The next-generation hotend is rated at 40 mm³/s, so 0.6 mm and 0.8 mm nozzles are worth fitting for large ABS or PA parts where you want thick walls down fast and fewer layers for shrinkage to act on. The stock 0.4 mm nozzle is bimetal with a hardened steel insert, shared with the Q2, so PLA-CF, PETG-CF, PA-CF and glass-filled grades go straight in. Heat-up is slow: expect a wait while the nozzle climbs to 350 C, the bed to 100 C and the chamber to 65 C before a high-temperature job starts.
QIDI Plus5 specs that affect filament
PLA needs a different approach on this machine. A hot chamber plus a dense PLA part is how you get heat creep, which is why QIDI sells the Polar Cooler, an add-on that pumps below-ambient air straight at the extruder so you can keep the chamber warm without softening filament in the heatsink. Without it, vent the chamber and leave the heater off for PLA and PETG. Filtration is a three-stage activated carbon and HEPA stack that keeps ABS and ASA fumes inside, and the QIDI Box adds four spools of 65 C drying, which nylon and PC need more than most owners expect.
Filament notes for the QIDI Plus5
- The regulated 65 C chamber, 120 C bed and 370 C hotend make ABS, ASA, PC, PA and PPS-CF the point of this machine.
- Leave the chamber heater off and vent the top for PLA and PETG, or fit the optional Polar Cooler to avoid heat creep.
- The 40 mm³/s high-flow hotend pays off with 0.6 mm and 0.8 mm nozzles on large engineering-polymer parts.
- Stock 0.4 mm bimetal nozzle has a hardened steel insert, so CF and GF filled filament prints without a swap.
- Three-stage activated carbon and HEPA filtration keeps styrene fumes in the chamber when the doors are shut.
- Allow extra preheat time: reaching 350 C nozzle, 100 C bed and 65 C chamber together is not quick.
- Nylon and PC must be dry, and the QIDI Box is the only drying QIDI builds into this ecosystem.
