I've added pictures of the prototypes I printed at home to the catalog listing.
At first I laughed... then I realized some of the stainless steel fender trim might seriously be a candidate for printing. Larger sheet metal probably won't be economical to print, but I'll see what pricing looks like for smaller metal trim pieces first before I say never. But hey, if I print stainless steel quarter panels, at least they ought to hold up well if anyone wants to pay what they'd cost! :D
