“The innovation is a robotic arm with a print head that extrudes metal strong enough to support structure,” says Federal. A group of Dutch manufacturers stumbled on this little fact when they were looking for a way to 3D print furniture. The size of most 3D printed objects is constrained by the size of the 3D printer they’re printed in. He’s currently producing a feature length documentary called “ 3D Printing Revolution.” Here’s what wowed him in 2015. Federal is a filmmaker out of North Carolina, and a “3D printing evangelist” as he describes himself. What were the key developments of the year that brought us closer to 3D utopia? Brian Federal gave us his favorites. ![]() With new materials, new methods, and new applications, the young field is revolutionizing prototyping and manufacturing, and changing the worlds of design, medicine, construction, and, of course, hobbying. The year 2015 saw 3D printing continue its march into every dimension of our lives.
