So with all this talk of things like 3D printer guns has anyone here actually bought a 3D printer, or perhaps a small CNC rig? I'm considering both at this point. The 3D printer option has the benefit of being able to make some rather complicated shapes, that include inner voids, but you're restricted to a couple of types of plastic. CNC lets you work with multiple materials, but you're somewhat restricted in the sort of thing that you can make.
