Description
The QIDI Max4 is a large-format enclosed CoreXY printer that QIDI Technology unveiled at Formnext 2025. It's a flagship machine with a 390x390x340 mm build volume and an industrial-grade high-temperature package. It's aimed at experienced users and small print farms who need to print large functional parts in engineering materials in one piece, without splitting them up.
The print head pairs a bimetal nozzle that hits 370 °C with a 120 °C bed, and a 3rd-gen actively heated chamber (PTC, 500 W) holds up to 65 °C, so ABS, ASA, nylon, polycarbonate, and carbon fiber composites print without warping. Travel speed reaches 800 mm/s, with real-world print speeds around 600 mm/s at up to 30,000 mm/s² acceleration; a PLA Benchy finishes in 18 minutes. It rides on an all-metal CoreXY frame with 10 mm 1.5GT belts and FOC closed-loop stepper motors, a linear rail on the X axis, and dual independent lead screws on Z. Auto leveling uses a load cell sensor in the hotend, and you also get a 1080p AI camera, a filament runout sensor, power loss recovery, and 3-stage air filtration (H12 HEPA + activated carbon). An external Polar Cooler unit and QIDI Box multi-color support are optional add-ons.
Advantages
- Huge build volume — 390x390x340 mm lets you print large enclosures and functional parts in one piece, no gluing
- High-temp package — a 370 °C nozzle, 120 °C bed, and active 65 °C chamber let you print ABS, ASA, nylon, polycarbonate, and PA-CF / PC-CF composites without warping
- Accurate geometry and clean walls — iXBT measured 0.01-0.03 mm deviation on a calibration cube, with no Z banding and no ringing artifacts on complex surfaces
- Smooth surface finish — AppleInsider's reviewer said you had to go looking for the layer lines on PLA Rapido Matte
- Open ecosystem — print from QIDI Studio, OrcaSlicer, or PrusaSlicer over Wi-Fi (2.4/5 GHz), Ethernet, or USB, with no mandatory cloud
- Print protection and easy start — the 1080p AI camera catches print failures, and setup takes about 5 minutes following animated on-screen prompts
Disadvantages
- Very loud with the Polar Cooler — 56 dB without it, 62 dB with the Polar Cooler running (AppleInsider compared it to an angry Roomba in the room)
- Dimensional drift on large parts — iXBT measured -0.23 mm on X over 100 mm and up to -0.33 mm at the 145 mm max, so you should compensate for big models
- Rough firmware and app — reviewers note the software is still being refined and the mobile app has a low camera-feed frame rate
- Big, heavy, and not cheap — 40 kg net and 558x578x612 mm means a two-person unboxing, and the $1,099 starting price isn't for a beginner
The QIDI Max4 suits experienced users, engineers, and small print farms who need an enclosed, actively heated chamber and a large build area for big functional parts in ABS, ASA, nylon, and composites. It's not a first printer for a beginner: the price, size, and weight are aimed at people who already know what they want from 3D printing.
Bottom line: the Max4 packs industrial-class capability into a desktop case, with a big build area, a high-temp hotend, and an active chamber. Its strength is large single-color prints in demanding materials; its weak spots are the noise with active cooling and the rough software at launch.
