| Software notes | The device offers flexible connectivity manageable via integrated wireless network or standard USB port, facilitating the transfer of print files without physical proximity constraints. It natively supports the main formats generated by the most popular slicing software in the resin 3D printing landscape, such as CHITUBOX and Voxeldance Tango, ensuring full compatibility and flexibility in the digital workflow. The proprietary firmware ensures smooth management of settings directly from the touch screen interface integrated on the machine. Since no mandatory dependencies on closed cloud platforms are found, the user maintains total control over their files and local print preparation, guaranteeing maximum data privacy and operational continuity even without an internet connection. | 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. |
