When trying to begin to Print over USB The following error is displayed

"Unable to Export to Selected Location"

the only way I can work around this is to save to disk and then print from the library.

Where is this path set?

An interesting test would be to run the application as super-user to see if it still has the export issue. That would at least narrow it down to a permissions thing.

For example, you can go to Applications > Utilities > Terminal and type
cd /Applications/Simplify3D-2.1.0/Simplify3D.app/Contents/MacOS/
sudo ./Simplify3D
