The printer is essentially the same as any paper employing printer, except these ones use molten plastic and build them in layers in a process called Fused Deposition Modeling. So the one at Specialized is a Dimension SST 1200 that builds a model in layers of 0.010 inches thick. Its pretty fascinating to see one in action. Like this :
Do you use 3D printers in your projects? I haven't, but I have often wondered about the kind of part geometries these things can't handle. I have seen parts made from 3D printers and those ones don't look too nice surface finish wise. But hey, it gives the message.
