Software notes 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. 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.
