Jay Leno likes 3D printing too! He uses the same Dimension printers that we do, and it is great that he is so enthusiastic about the technology. My only gripe: they make scanning and using the resulting file look a bit too easy. I'd love for it to be so simple but generally once a part has been scanned it still requires quite some work by an experienced modeller to make the mesh manifold so that it actually can be printed.
