Software notes The printer is controlled via Bambu Studio, the proprietary slicer available for Windows, macOS, and Linux, as well as the Bambu Handy mobile app. LAN mode is supported, allowing full local control without an internet connection or cloud account. Remote monitoring via Bambu Cloud is optional. Bambu Studio accepts 3MF, STL, OBJ, and STEP files and includes advanced features such as vibration compensation and flow rate control. The machine comes with the proprietary Qidi Print software, a slicer based on proven open-source architectures, specifically optimized for the profiles of the technical materials supported by the printer. Users can still generate G-code using other widely adopted third-party slicers on the market, such as Ultimaker Cura, PrusaSlicer, or Simplify3D, after manual configuration of machine and extruder parameters. Although it lacks native cloud features or advanced remote connectivity for corporate fleet management, it supports direct file transfer via local Wi-Fi or USB drives, ensuring a secure offline workflow for intellectual property protection.
