I'll agree it's a very limited 3D printer, but that's more to do with the very simplified programming (the wire) rather than any specific limitation of the concept that the machine uses. It would be easy enough to add a changeable cam to the wire guide to add changes to the r-axis dependant on angle. Even then it would only be able to do simple shells.
