Software notes The H2D uses Bambu Studio as its official slicer, available for macOS and Windows. Third-party slicers that export standard G-code — including PrusaSlicer, SuperSlicer and Cura — are also compatible, though certain advanced proprietary features (such as automatic dual-nozzle offset calibration and Material CodeSync) are only accessible within the Bambu ecosystem. Remote monitoring and control are handled via Bambu Handy; Bambu Suite manages laser engraving and cutting workflows. The printer operates with Klipper firmware pre-installed on a 64-bit ARM processor, enabling advanced standard features like input shaping and pressure advance. The user interface is managed via a removable capacitive touchscreen and a dedicated web interface (Fluidd or Mainsail) for remote control and monitoring via Wi-Fi or LAN connection. For file preparation, the machine is compatible with major slicers on the market, including Elegoo Cura (bundled by the manufacturer), UltiMaker Cura, PrusaSlicer, and OrcaSlicer.
