Software notes Print job management is handled by the proprietary PreForm software, which enables automatic model layout, optimized orientation, and guided generation of retention supports. The program integrates preconfigured and validated print profiles for all proprietary materials, reducing the need for manual calibrations by the user. Through the Dashboard cloud platform, users can remotely monitor production progress, manage print queues for multiple devices, and analyze material consumption. The software architecture requires a network connection for advanced monitoring features, but it also allows files to be transferred via local USB, Ethernet, or Wi-Fi connections, ensuring operational flexibility inside the laboratory. 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.
