| 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. |
