PreForm, developed by Formlabs, serves as the dedicated 3D printing preparation platform for the company’s stereolithography and selective laser sintering systems, converting raw CAD meshes into machine-ready print jobs in a matter of minutes. Operating within the 3D printing / CAD category, the application imports STL or OBJ files, automatically generates support structures, calculates optimal print orientation, and slices the geometry into the layer stack required by Formlabs hardware; users can override any automatic decision with manual tools for support editing, raft adjustment, and resin-tuning parameters. The current stable release, version 3.57.0.622, is the 39th numbered iteration of the program, reflecting a continuous update cycle that has added features such as one-click print, adaptive layer thickness, and remote job queuing for networked printers. Typical use cases span jewelry design, dental model production, engineering prototypes, and detailed miniatures, where fine surface finish and dimensional accuracy are critical. PreForm integrates directly with Formlabs’ material library, automatically suggesting exposure settings for each resin type and warning when model geometry exceeds printer build volume or violates minimum thickness constraints; built-in print-time and resin-volume estimators help operators forecast cost and duration before committing to the build. The software also maintains a history log that can re-open past projects with identical settings, streamlining repeatability for small-batch manufacturing. PreForm is available for free on get.nero.com, with downloads supplied through trusted Windows package sources such as winget, always delivering the latest version and supporting batch installation alongside other applications.
