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 operates primarily through third-party slicing software widely adopted within the maker community, such as ChiTuBox and Lychee Slicer, ensuring high flexibility in file preparation. Integration with these programs allows granular control over exposure parameters, support generation, and lift times. The machine features no integrated wireless connectivity or reliance on cloud platforms, requiring completed print files to be transferred exclusively via a removable USB flash drive. This configuration guarantees complete offline operational autonomy and mitigates the risk of interruptions caused by network issues or forced remote software updates.
