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. The machine is compatible with major slicing software on the market, offering maximum freedom in the workflow. Fully supported by CHITUBOX and Lychee Slicer, it reads the proprietary .CTB and .PRZ formats. Thanks to continuous updates of resin profiles, users can quickly import optimal printing parameters. File management and job initiation occur primarily through the local touchscreen interface and loading via USB drive, maintaining an offline and secure operational setup suitable for production environments.
