Interview in Scientific American about 3D Printed guns

After a University of Texas at Austin law student successfully discharged a 3D printed gun earlier this year, Scientific American interviewed Ryan Wicker – Director of the Keck Center for 3D Innovation – about the implications of the event.  Although somewhat alarmed by the printed weapon, Wicker mentions that he is far more concerned about what one might fabricate in a traditional machining shop – rather than with an inexpensive desktop 3D printer.
