Yes this may be the way of the future. I've already had several parts made for a model ship that I'm building. It looks like the only way for me to go make the rocker panel molding clips for the '63 Sport Fury rocker panel moldings since I can't find them anywhere after several years of searching.

Subject: 3D-printed car parts
This article is about 3D-printed car parts in manufacturing, but it is not a stretch to think about the ability of future 3D printers to make new parts for older cars too, like 1962 to 1965 Mopars. Surrogate NOS stock, so to speak.
