Software notes The operation of the machine is primarily managed via third-party slicing software widely utilized within the resin 3D printing industry. The system natively supports file formats generated by programs such as ChiTuBox and Voxeldance Tango, offering the user the flexibility to choose their preferred interface for model preparation, support generation, and exposure parameter optimization. There is no native Wi-Fi connectivity or dedicated cloud management in this standard version; therefore, the transfer of print-ready files occurs traditionally via a USB port located on the machine body, ensuring a stable, independent, and completely offline workflow. 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.
