How do 3D printers work?
3D printers are pretty awesome. Unlike the machines that print pictures or words on paper, 3D printers can create things you can hold in your hand – like fun-shaped food, cameras and even guitars. So how do they do it? We asked printing expert Robin Schwartzman from the University of Minnesota to help us find the answer. Got a question that jumps off the page? Send it to us at BrainsOn.org/contact, and we’ll see if we can get an answer to materialize.
