Plus4
Fused filament fabrication (FFF/FDM)
F2 · Intermediate
QIDI Plus4 sits in the prosumer segment thanks to its combination of a large build volume (305x305x280 mm) and advanced features suitable for demanding enthusiasts and small offices. The CoreXY structure ensures high stability and print speeds up to 600 mm/s. The active chamber heating, reaching 65 °C, and the bimetal nozzle capable of operating up to 370 °C allow for the reliable processing of complex engineering polymers like ABS, PC, and carbon or glass fiber-reinforced materials. This versatility, combined with native Klipper firmware integration and optional support for multi-color printing, makes it an ideal solution for those seeking superior performance without the costs of an industrial machine.

Software
The machine relies on an architecture based on Klipper firmware, which provides advanced computational performance and native features like input shaping to reduce vibrations during high-speed movements. Users can interface via the integrated 5-inch touchscreen or through the standard Klipper web interface. The recommended official slicing software is QIDI Studio, a program derived from PrusaSlicer and Orca Slicer, optimized to leverage the machine's profiles and proprietary print parameters. However, the system maintains an open approach and is fully compatible with third-party slicers such as Orca Slicer, PrusaSlicer, and Cura, ensuring maximum flexibility in the daily workflow.
Reviews from those who use this machine every day will be available in the next version of the platform.
