PreForm
PreForm is the primary control and preparation software for Formlabs 3D printers, used by engineers, designers and manufacturers to position models on the print bed, add support structures, configure print parameters, and send jobs to Form 3/Form 3L/Form Pro printers. It handles model import (STL, OBJ), orientation and slicing, and provides real-time preview of print outcomes. PreForm is essential for anyone running a Formlabs printer on their Mac and typically runs continuously during print preparation workflows.

1 suggestionPreForm is currently Intel-only and does not have a confirmed native Apple Silicon build in public release. Formlabs has acknowledged on their community forum that they are working on a solution to keep PreForm on Mac, but have not published a timeline. Since Rosetta 2 will be removed in macOS 28 (September 2028), you should contact Formlabs directly to ask for an estimated delivery date of a native build — this will help you plan whether to upgrade your Mac or delay hardware changes until a native version is available. In the meantime, the Intel build continues to work under Rosetta 2 today, but the September 2028 deadline is firm. If Formlabs does not release a native version before then, you may need to either keep an older Mac running a pre-macOS 28 system, or explore alternative slicing software that ships with native Apple Silicon support.
