Takes forever to use an English wheel and hammer to shape body parts. A 3D printer of this type will be a game changer. I've created some parts for my '60s vintage cars. It would be nice to print parts with modern conveniences built in, like cup holders, cellphone holders etc. Just can't buy something like that from the replica part sellers; so you can design and print your own with a printer like this.
With these printers, not that far from now, you could print anything you can imagine.
