| Software notes | The device natively supports the proprietary ChituBox preparation software and is fully compatible with popular third-party slicers in the industry. File management and remote monitoring are handled via the desktop application connected to the local Wi-Fi network. Advanced functions of the integrated camera enable automatic time-lapse video generation and anomaly identification during the placement of initial layers. File transfer is not bound to mandatory proprietary remote servers, ensuring operational continuity offline via the USB port. | 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. |
