Bambu Lab H2C vs Qidi Tech Max4
Technical comparison · Fused filament fabrication (FFF/FDM)
The H2C and the Max4 are both professional FDM printers, but with a huge price gap: the H2C costs more than double the Max4. The difference comes down to the multi-extruder, rated speed and the larger bed on the Max4.

| Software notes | The printer is operated through Bambu Studio, Bambu Lab's open-source slicer based on PrusaSlicer, available for Windows, macOS, and Linux. Remote control is available via the Bambu Handy app or Bambu Suite. The machine includes a 5" color touchscreen for local operation and connects over dual-band Wi-Fi. The firmware is proprietary; Klipper is not natively supported. | 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 about €1200 less
- Bed size: the Max4 offers 390×390 mm versus 330×320 mm on the H2C
- Multi-extruder: only on the H2C
- Native Klipper: only on the Max4
- Top speed: the H2C is rated at 1000 mm/s versus 800 mm/s for the Max4
Which one to choose
Choose H2C if…
you work with multiple materials at once (water-soluble supports, different colors, TPU next to PLA) thanks to the multi-extruder, and want to stay inside the Bambu Studio ecosystem: the H2C prints faster (1000 vs 800 mm/s) but costs over €1000 more.
Choose Max4 if…
you want a larger bed (390×390 vs 330×320 mm) and native Klipper at roughly half the price: the Max4 gives up the multi-extruder but is the more rational choice if budget matters more than top speed.
