Description
The QIDI Plus4 is an enclosed mid-range CoreXY printer that QIDI Technology launched in late 2024. It's built for engineering and high-temperature materials: an actively heated chamber up to 65 °C, a 370 °C nozzle, and a 120 °C bed. It targets experienced users, small workshops, and anyone who wants to print ABS, nylon, polycarbonate, and carbon fiber composites without warping.
The build volume is 305x305x280 mm, noticeably larger than most enclosed rivals in this price range. It's built on a steel CoreXY frame with dual independent lead screws on the Z axis. The print head pairs a hardened-tip bimetal nozzle with an 80 W heater and a direct drive extruder geared 8.9:1. Travel speed reaches 600 mm/s, with real-world print speeds around 300-350 mm/s at up to 20,000 mm/s² acceleration. A 400 W PTC heater brings the chamber to 65 °C in 5-8 minutes. It runs Klipper 0.12 with the Fluidd web interface, plus a 1080p AI camera, a filament runout sensor, power loss recovery, and compatibility with the 4-spool QIDI Box.
Advantages
- Full high-temp package — a 370 °C nozzle, 120 °C bed, and active 65 °C chamber print ABS, ASA, nylon, polycarbonate, and carbon fiber composites; 3DPrint.com ran 300+ hours with just one minor failure
- High accuracy — Tom's Hardware and Notebookcheck called parts "exceptionally accurate and square" with roughly 0.05 mm tolerance, thanks to the rigid steel frame and dual independent Z screws
- Big enclosed chamber 305x305x280 mm — larger than the Bambu Lab X1C at a comparable price, with room for bulky functional parts and cosplay models
- Open ecosystem — Klipper 0.12 firmware with the Fluidd web interface, printing from QIDI Studio, OrcaSlicer, Cura, or PrusaSlicer over Wi-Fi, Ethernet, or USB, with no mandatory cloud
- Quiet operation — around 60 dB on average, even quieter with the doors closed, so it's fine to keep in the same room
- Optional multi-color — compatible with the 4-spool QIDI Box that dries filament while it prints
Disadvantages
- Weak air filtration — Notebookcheck found the stock filtration ineffective, so the chamber needs extra ventilation when printing ABS and ASA
- Hot stepper drivers — 3DIY and Notebookcheck saw the TMC2240 drivers reach 100 °C during normal printing
- Flaky Wi-Fi and rough localization — reviewers note the Wi-Fi module sometimes refuses to connect and the non-English menu translations are poor; English is recommended
- Tall prints hit the chamber heater — prints above 270 mm can trigger thermal protection and cancel the job
The QIDI Plus4 suits experienced users and workshops that need a large enclosed, actively heated chamber for engineering and high-temperature materials. It's a strong pick for functional parts in ABS, nylon, polycarbonate, and composites, as well as big cosplay models. Beginners who want plug-and-play printing with no tuning will have an easier time with starter machines.
Bottom line: the Plus4 packs a lot of capability for the money, with a high-temp hotend, active chamber, and big build area usually found in much pricier machines. Its strength is printing demanding materials with solid accuracy; its weak spots are air filtration and networking.
