This is obviously a long overdue update. I was presented an opportunity to have nose and tail portions of the car 3d printed... yes, 3d printing part of the body buck! I bet this is the first time you will read that. While 3d printing full scale may not be an economic solution for building a whole car, there are a lot of opportunities to print detailed parts or molds (very quickly). I didn't even consider this earlier on in the build, because I just didn't know printing in this scale was possible. The massivit printer prints something like 1foot per hour for something of this size- it's nuts, and puts my rinky dink desktop 3d printer to shame.
While I could use these printed parts to build sheet metal panels directly from, I will be bodyworking and painting these printed pieces and pulling splash molds from them and will build the sheet metal from a fiberglass part instead.
After slicing to my liking, preparation of the model and printing was done by the sign connection in Gastonia, NC on their Massivit 3d printer and anyone stateside who's serious about printing larger parts should definitely be talking with them.
