| Software notes | The A2L is compatible with Bambu Studio, Bambu Lab's proprietary slicer for Windows and macOS, which provides native access to all machine features including AMS multi-color management. Third-party slicers that export standard G-code — such as PrusaSlicer and OrcaSlicer — are supported, though some advanced features may not be available outside Bambu Studio. Connectivity is via Wi-Fi; basic printing functions do not require a cloud account. | 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
- Multicolor: accessory on one extruder versus four toolheads → the U1 has no accessory to buy but stops at 4 colours, the A2L goes up to 19.
- Build volume: 330 × 320 × 325 mm versus 270 × 270 × 270 mm → on the U1 a part over 270 mm has to be split.
- Price: 379 € versus 849 € → the A2L costs 470 € less.
Which one to choose
Choose A2L if…
You print parts up to 330 × 320 mm in one or a few colours and want to stay at 379 €. For multicolor you buy the accessory, which goes up to 19 colours; the bed heats to 80 °C (manufacturer-declared values).
Choose U1 if…
You print in several colours or materials with no accessories, with four toolheads in a single print, and want open Klipper firmware, with Moonraker and Fluidd, that you can customise; a 1080p camera is built in. The volume is 270 mm per side, colours top out at 4 and you pay 470 € more.
