| Software notes | Print process management is handled by PreForm, a highly optimized proprietary software that automates model orientation, support generation, and slicing using advanced algorithms. PreForm offers an intuitive interface and diagnostic tools that minimize print failures. Although it is not possible to use third-party open-source slicers due to the closed nature of the ecosystem, the native integration ensures perfect calibration with original materials. The software includes network file transmission capabilities and is tightly connected to the Dashboard cloud platform, which enables remote monitoring of printers and resin consumption, without being strictly mandatory for the machine's core offline operation. | The device ensures broad compatibility with the main third-party slicing software programs available on the market, including widely used solutions such as ChiTuBox and Lychee Slicer. File management is primarily handled via offline transfer using the USB port located on the front of the chassis, or by utilizing the wired Ethernet network connection for remote monitoring within a local network. There are no restrictions or dependencies on proprietary cloud platforms, allowing users to work in complete autonomy and protect the intellectual property of their print files without requiring an active internet connection during the manufacturing process. |
