Hey guys, couple of questions inspired by the picture included. I thought at first it was being produced, but looks like it's a set of plans to 3D print the thing. I know nothing about 3D printing, so I'd thought I'd ask since I've seen some pretty cool things made that way.
First, is there printers that do it in metal? What are the limitations on them? Can they do tracks or other parts? You'll have to pardon the ignorance on the subject, but I'm curious. If there's any resources to answer these questions, please put the link so I can enlighten myself. Any help is appreciated.
