Bambu Lab H2S vs Snapmaker U1
Technical comparison · Fused filament fabrication (FFF/FDM)
Bambu Lab H2S and Snapmaker U1 sit at a similar price, but they solve multicolor printing in opposite ways: the H2S bolts on an external AMS, the U1 mounts four independent toolheads on its turret. The difference matters most to anyone who switches colors often, or who prints technical materials.

| Software notes | The H2S uses Bambu Studio as its primary slicer, with full support for proprietary features including automatic calibration, AI monitoring, and AMS management. It also accepts G-code exported from OrcaSlicer, PrusaSlicer, and Cura, though some advanced functions may not be available with third-party slicers. Laser and cutting functions are managed exclusively through Bambu Suite. Developer Mode is available, exposing MQTT access for custom integrations. | The primary software is Snapmaker Orca, an optimized version of the popular OrcaSlicer, which provides native management of the four toolheads and factory-calibrated material profiles. The printer can also be seamlessly managed via the Snapmaker mobile app for remote monitoring, taking advantage of the built-in 1080p camera. The internal firmware is built on Klipper, Moonraker, and Fluidd, which Snapmaker has made open-source, allowing experienced users to customize the machine and integrate it into complex workflows. |
The differences that matter
- Enclosed chamber only on the H2S: the only way here to print ABS/ASA without warping.
- Multicolor: external AMS with purge on every swap on the H2S versus four independent toolheads with no purge on the U1.
- Bed size: 340×320 mm on the H2S against 270×270 mm on the U1.
- Native Klipper only on the U1, versus the H2S's Bambu Studio/Suite ecosystem.
- Price: around €1200 for the H2S against €849 for the U1.
Which one to choose
Choose H2S if…
The enclosed chamber and 350°C hotend make the H2S the pick for ABS, ASA and nylon without warping, while the bigger bed (340×320 mm against 270×270 mm) fits larger single parts. It's the right machine when the material matters more than how many colors go into one print.
Choose U1 if…
The U1's four toolheads switch color without purging filament, unlike the H2S's external AMS, which needs a separate accessory and purges on every swap: for anyone printing multicolor often on small parts, that time and material saving adds up print after print. Native Klipper also opens up tuning and community support for anyone who wants to touch the firmware, and the price stays under €900.
