One of the first of these companies I was exposed to was 3D Systems back in 1986. Back then it was used primarily as product prototyping, and still is. Amazing technology and the indusrty has come a long way very quickly. Today there are forums and downloads for design files. You can make anything from a microscopic piano, to a fully functioning semi-auto.
Lou, your son made a fabulous grill. Can't wait to see it mounted!
