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 machine is compatible with major slicing software on the market, particularly CHITUBOX and Lychee Slicer, natively supporting .CTB and .PRZ formats. It features 8 GB of internal memory and supports file transfer via USB port and Wi-Fi connectivity, allowing a versatile workflow without the requirement to rely on cloud platforms. Direct interaction with the printer is handled via a 5-inch touchscreen that provides a simple and responsive interface for operational control.
