| 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, offering maximum freedom in the workflow. Fully supported by CHITUBOX and Lychee Slicer, it reads the proprietary .CTB and .PRZ formats. Thanks to continuous updates of resin profiles, users can quickly import optimal printing parameters. File management and job initiation occur primarily through the local touchscreen interface and loading via USB drive, maintaining an offline and secure operational setup suitable for production environments. |
