When it comes to affordable professional-grade 3D printers, QIDI Tech has become a name to trust. The QIDI Plus 4 continues that legacy with next-gen performance, industrial-level precision, and dual extrusion capabilities — all at a price that undercuts most competitors.
Build Quality and Design
The QIDI Plus 4 boasts a fully enclosed metal frame, offering both temperature stability and reduced noise. Inside, a CoreXY motion structure ensures smoother, faster, and quieter printing — ideal for high-precision jobs or multi-material prints.
The printer’s 7-inch touchscreen and intuitive QIDI Studio interface make it easy even for first-time users.
Performance and Speed
Thanks to the Klipper firmware pre-installed, the Plus 4 can reach speeds up to 600 mm/s while maintaining dimensional accuracy. Combined with its auto-leveling bed and dual Z-axis design, the printer delivers consistent results, even on long prints.
Pro tip: The “input shaping” feature minimizes vibration — you can print faster without ghosting or layer shift.
Dual Extrusion for Creative Flexibility
One of the biggest advantages of the Plus 4 is its independent dual extruder system (IDEX).
This allows:
- Multi-color printing
- Soluble support material (PVA, HIPS)
- Duplicate and mirror mode for double productivity
It’s a feature normally reserved for machines twice the price — a huge win for makers, small businesses, and educational labs.
Material Compatibility
QIDI designed the Plus 4 to work seamlessly with multiple filament types:
- PLA, PETG, ABS, ASA
- Nylon, Carbon Fiber, PA12-CF
- TPU flexible filaments
The enclosed chamber keeps temperature constant, which means less warping and better layer adhesion — even with industrial materials.
QIDI Studio & Firmware
QIDI’s own slicing software, QIDI Studio, is optimized for the Plus 4. It provides easy-to-use presets for all QIDI materials and allows remote monitoring through QIDI Link (mobile app).
Unlike open-source slicers, QIDI Studio is calibrated for out-of-the-box precision — perfect for non-technical users.
