I'd likely be scanning parts. Especially if it does not require any crucial dimensions.
I might also scan parts that I am investigating (as an engineer) to be able to perform rough dimensional analysis.
Lastly, if it's flexible enough and can scan inside cavities, I might do that to create a 3D map of a space so I can for a part into that cavity.
Much of this would be done with the intent of using my 3D printer.
