Hey Feign
Have you built some of this?.... it seems to be a new way to scanning that I havent seen documented anywhere.
Ive read you post quite a few times and I think Iv got it modled right in my head now.... hold up this would take just a few min in blender, im just going to go do it...

ok so something like that ... where the yellow box is the peachy printer and so using the mirrors you can hit the object from ALOT of angles.
and obliviously the laser wouldn't keep going threw the object being scanned like it dose in this screen shot.

It seems to me that its possible that you don't need to rotate the object smoothly, instead you could just re position it 3 or more times.
