The neatest thing for me is, of all the best brains since time immemorial, Dan Gelbart's is still alive in my lifetime.

There was a segment on jay Leno's garage a few years ago which focused around the 3d metal printing of parts for vintage cars. parts which would otherwise be next to impossible to reproduce today as identical replacements for the originals. While CNC could machine out a new part to work the surface texture and shapes would be the dead giveaway that it was a new part. So the rapidia printer was used to make the part what ever it was. Plus they used the 3d digital scanning stylist to copy an image of the old part into cad then that image was sent tot eh printer just as a plastic 3d printer could do a day or so later they had their replacement part. A little matting surface clean up was all that was needed to fix the old car.
I thought it was a brilliant solution for antique and vintage restorations.

I saw on e where they scaned the racecar engine bay with the engine in it for all clearances. and then printed the inconell turbo header for the inline 6 cylinder. it was done in about 3 sections due to the small 3d printer. then welded togeather. it was possiably the prettyest thing Ive ever seen printed. they made a plastic one first to be sure it was right and to send to the fab shop to make a stainless tubular unit too as they had a race they had to get to and did not know if the 3d printed inconell header would be finished in time, it's on utube somewhere... dam I wish i had one of those printers. oh the stuff I could make...if I only had a clue.
