It's amazing, but I'm a bit confused. What if the finished part or tool needs to be metal? You've still got to take the prototype to a machinist or foundry don't you? How is taking a copy of the original better than taking the original? The D Valve thing Leno had in his video could be scanned and replicated in plastic, but wasn't it an engine part? In plastic?
