How extensible will the 3d files be? Can we convert them to DXF and modify them in AutoCAD now, or will that be added in later?<p>Even if not, people will still scan and upload scans of common objects, such as the battery cover to a remote control or controller or wiimote. Someone (Google? Make?) will host the Youtube/Github of 3d image scans, where people will freely upload their scans.<p>And there are all kinds of other prototyping situations where this could be used -- make a model out of clay or balsa or your favorite malleable material, scan it, then print it from the 3d printer.<p>Which leads to fast physical prototyping -- 3d-print a model, modify it with hand or power tools (box knife, file, dremel), scan, modify the shape file in AutoCAD, 3d-print, modify by hand, scan, modify in AutoCAD, etc.
