Lipson talks about the future of 3-D printing

The promise and perils of 3-D printing, and particularly the printing of electronics and other active, integrated systems, was the topic of a Feb. American Association for the Advancement of Science (AAAS) talk by Hod Lipson, associate professor of mechanical and aerospace engineering and of computer science. Lipson, a 3-D printing and artificial intelligence expert, participated in the AAAS panel titled "Organizing the Innovation System for Advanced Manufacturing." The symposium explored the role of additive manufacturing in industrial production, which includes 3-D printing, and how the emergence of robotics is also changing manufacturing processes today. Insights provided included industry, academic and science policy views on manufacturing today. Lipson gave an overview of 3-D printers - machines that can automatically fabricate arbitrarily shaped parts, layer by layer, from almost any material. He talked about how 3-D printing has evolved over the last three decades from limited and expensive prototyping equipment in the hands of few, to small-scale commodity production tools available to almost anyone. It has been broadly recognized that the burgeoning revolution will transform almost every aspect of life, Lipson said.
