| 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, particularly CHITUBOX and Lychee Slicer, natively supporting .CTB and .PRZ formats. It features 8 GB of internal memory and supports file transfer via USB port and Wi-Fi connectivity, allowing a versatile workflow without the requirement to rely on cloud platforms. Direct interaction with the printer is handled via a 5-inch touchscreen that provides a simple and responsive interface for operational control. |
