3d printers look pretty awesome, but I can't help but think that this youtube clip was a little doctored. Not because of the printer, but because of the scanner.
Can they really figure out the mechanics of a crescent wrench that quickly with their awesome scanner gizmo?
I believed my eyes for a minute it until I started reading the comments and got to thinking that it seemed a little strange. How could the inside of the crescent wrench be discovered by reflecting light at it? How could it discover, without some sort of x-ray, gears you can't even see?
