In 2013, Texan crypto-anarchist Cody Wilson uploaded blueprints for The Liberator, the world’s first 3D printed gun. What followed was a fiery debate over whether or not 3D printed guns should be legal.

Producer Cheyne Anderson explores how the 3D printed gun taps into deep anxieties playing out in the United States. She chats to Tim Lytton from the Georgia State University College of Law about the historical context of the debate. Then she chats to Aaron Seymour (University of Technology Sydney) about unpacking the utopian promises of 3D printing and Richard Matthews (University of Adelaide) about the practical challenges getting in the way of their widespread use.
