| Software notes | The printing process is managed by the proprietary PreForm software, a closed application that automatically optimizes model orientation, support generation, and production time calculations. This software environment is designed to ensure a highly streamlined and standardized workflow, ideal for professional contexts where result predictability is crucial. PreForm integrates seamlessly with the manufacturer's ecosystem, receiving continuous updates that introduce new profiles for proprietary resins. The machine also offers optional access to Fleet Control and the cloud-based Dashboard platform, which are advanced tools that allow users to monitor print queues, manage multiple units in parallel, and track material consumption in real time remotely. | The device ensures broad compatibility with the main third-party slicing software programs available on the market, including widely used solutions such as ChiTuBox and Lychee Slicer. File management is primarily handled via offline transfer using the USB port located on the front of the chassis, or by utilizing the wired Ethernet network connection for remote monitoring within a local network. There are no restrictions or dependencies on proprietary cloud platforms, allowing users to work in complete autonomy and protect the intellectual property of their print files without requiring an active internet connection during the manufacturing process. |
