Bambu Lab H2S vs. Qidi Max4
Both printers compared directly. The better value is marked in green, where this can be determined objectively.
The key differences
- The Qidi Max4 has the larger build volume (390 × 390 × 340 mm).
- According to the manufacturer, the Bambu Lab H2S is faster (up to 1,000 mm/s). In practice, though, print time depends heavily on material and settings.
- The Qidi Max4 reaches higher nozzle temperatures (370 °C), which makes it better suited to engineering filaments.
