Ecosystem
Cloud dependency No No
Software notes The machine is supported by major slicing software on the market, including optimized profiles for CHITUBOX and VoxelDance Tango, ensuring broad operational flexibility. The system relies entirely on USB connection for file transfer and offline printing, eliminating any dependency on cloud services. The onboard interface is managed via a practical 3.5-inch resistive touchscreen that allows users to start prints, monitor basic parameters, and utilize automated diagnostic features, such as the initial self-check of mechanics and sensors. 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.
