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 offers broad compatibility with leading third-party slicing software options, notably popular solutions like Chitubox, Lychee Slicer, and Voxeldance Tango. This software flexibility prevents users from being locked into a restrictive, closed proprietary ecosystem, allowing them to utilize advanced support generation and model orientation algorithms. File transfer is handled entirely offline via a standard USB port, a design choice that prioritizes connection stability during data transmission but lacks native Wi-Fi connectivity or cloud-based management features. Material profiles are easily accessible and customizable, significantly streamlining the fine-tuning of exposure times for a wide variety of commercial 405nm photopolymer resins available on the market.
