| Software notes | The A1 works natively with Bambu Studio, Bambu Lab's proprietary slicer available for Windows and macOS, which handles slicing, automatic calibrations, and remote monitoring via the Bambu Handy app. Third-party slicers — including PrusaSlicer, SuperSlicer, and Ultimaker Cura — are supported via standard G-code export, but advanced features such as vibration compensation and active flow control are only available within the Bambu ecosystem. | 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. |

Which one to choose
Choose U1 3D Printer if…
you value multi-extruder, native klipper and work area. «A second extruder allows printing with two different materials in the same session: soluble support material for complex geometries, or a combination of rigid and flexible in the same part. It expands process capabilities but introduces calibration complexity and the risk of oozing from the idle nozzle. Most useful for work involving geometries that require supports difficult to remove manually.»
