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 device operates primarily through third-party slicing software widely adopted within the maker community, such as ChiTuBox and Lychee Slicer, ensuring high flexibility in file preparation. Integration with these programs allows granular control over exposure parameters, support generation, and lift times. The machine features no integrated wireless connectivity or reliance on cloud platforms, requiring completed print files to be transferred exclusively via a removable USB flash drive. This configuration guarantees complete offline operational autonomy and mitigates the risk of interruptions caused by network issues or forced remote software updates.
