What is an S3G file?

S3G files mostly belong to MakerBot Desktop by MakerBot. The S3G file extension is used to store instructions for printing the objects in 3D models that have been staged for 3D printing using MakerBot Desktop and printed with MakerBot Replicator, a 3D printer. The 3D objects referenced by the S3G file references models stored as OBJ or STL files. With the release of MakerBot Replicator version 2, X3G replaced the S3G format.

How can I open an S3G file?

You need a suitable software like MakerBot Desktop to open an S3G file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your S3G file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a S3G file directly in the browser:. Just drag the file onto this browser window and drop it.
