3D printing has been used for prototypes for a while. I read recently that Porsche is using 3D printing for short-run production. The surface finish on 3D printed parts is not particularly nice, so this probably works best for parts that are not visible. When I say "nice" I mean they cannot replicate wood grain or mirror finish with this process.
It has allowed manufacturers to correct design errors before going into production.
I recall buying a Contigo insulated mug for my car. The design was clearly not road tested. I could only drink top half of the drink before the bottom of the mug hit the ceiling of my SUV. Pre-production samples would have pointed this out (assuming they tested in a car and not in a showroom). Since I only used the mug for my car, I gave it away.
So I am not against short runs. I was just showing that it can make for some frivolous products, and in the Woodpeckers realm, very high quality frivolous products.
