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. 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.
