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. Printer control is managed by PreForm, Formlabs' proprietary print preparation software. This application automatically optimizes model orientation, support generation, and layout arrangement, integrating specific algorithms to maximize the yield of medical resins. The system supports standard file formats such as STL and OBJ. Through the Dashboard cloud platform, users can monitor print status, track material consumption, and manage job queues remotely for entire fleets of machines. Although network connectivity (Wi-Fi and Ethernet) facilitates advanced management, the printer retains the ability to operate in local mode via data transfer via USB.
