Last week a large part of the 3D printing industry gathered in Frankfurt to visit Formnext, an immense additive manufacturing trade show. In this episode, recorded in the hallway outside the Formnext show floor, we bring you interviews with three authorities on 3D printing: Joris Peels, editor-in-chief of 3DPrint.com; Nora Toure, founder of Women in 3D Printing, and A. John Hart, associate professor of mechanical engineering at MIT and co-founder of Desktop Metal. Visit http://bit.ly/2A4XIri to see links and background for this episode.
