Why is that? The program I use enables me to "unroll" any surface created to 2D. I print it, wrap it on the uncut stay, cut and bob's yer uncle. That will take decidedly less time than bringing a printed part to a fine polish.
Pure curiosity and knowledge question: what is the state of the art for for printed metal, what materials are printed and are they malleable enough to wrap?
