Bambu Lab H2D vs Qidi Tech Max4
Technical comparison · Fused filament fabrication (FFF/FDM)
H2D and Qidi Tech Max4 compete for the same advanced-printer budget but start from different premises: one bets on independent dual extrusion, the other on a bigger bed and a lower price. The choice comes down to the kind of job, not the headline speed.

| Software notes | The H2D uses Bambu Studio as its official slicer, available for macOS and Windows. Third-party slicers that export standard G-code — including PrusaSlicer, SuperSlicer and Cura — are also compatible, though certain advanced proprietary features (such as automatic dual-nozzle offset calibration and Material CodeSync) are only accessible within the Bambu ecosystem. Remote monitoring and control are handled via Bambu Handy; Bambu Suite manages laser engraving and cutting workflows. | The machine natively runs on Klipper firmware, offering comprehensive control and high computational speed for advanced features like input shaping. The user interface is managed locally via a large 5-inch touchscreen. Remote monitoring is facilitated by the integrated 1080p AI webcam with error detection for extrusion failures. For slicing, the manufacturer provides QIDI Studio, a software derived from PrusaSlicer/Bambu Studio, specifically optimized for high-temperature material profiles. Users can also access the Fluidd web interface for advanced control over the printer parameters and print offline via a USB drive or through the local network. |
The differences that matter
- Price: the Max4 costs €850 less than the H2D.
- Dual extrusion: only the H2D offers it, for independent multi-material prints in the same job.
- Work area: 390×390 mm on the Max4 versus 350×320 mm on the H2D — the Max4 fits bigger single-piece parts.
- Color count: the Max4 handles up to 16, the H2D up to 4 with the AMS accessory.
Which one to choose
Choose H2D if…
The H2D is the only one of the two with two independent extruders, useful for printing dissolvable supports next to the main material, or two different technical filaments without cycling through an AMS. Built-in multicolor tops out at 4 colors and still needs the AMS accessory. It costs €850 more than the Max4.
Choose Max4 if…
The Max4 has a 390×390 mm bed, larger than the H2D's 350×320 mm, useful for bulky single-piece parts. It runs native Klipper firmware, handy for anyone who wants to hand-tune input shaping and speed, and handles up to 16 colors against the H2D's 4. It costs €850 less than the H2D, but has no second independent extruder.
