Software notes The system utilizes an open software ecosystem, ensuring compatibility with the main slicing programs on the market, including ChituBox and Voxeldance Tango. The machine integrates built-in Wi-Fi connectivity for the remote transfer of print files via the official application or compatible software, eliminating the need to use physical USB drives for every operation. The internal firmware is based on an optimized version of Linux, which improves the responsiveness of the user interface on the built-in touch screen display and optimizes the handling of complex data originating from 9K files. Exposure parameters and resin profiles can be managed directly from the chosen software, offering precise control over curing times and axis movement speeds. 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.
