3D printing is revolutionizing manufacturing, but not without controversy. The technology has made printing guns in your home relatively easy and cheap using open-source code provided by organizations like Defense Distributed. The nonprofit came under fire from the State Department, which alleged that disseminating code to print 3D guns is akin to international arms trafficking. Evan is joined by Randal Meyer, a legal associate at the Cato Institute, which filed a brief in Defense Distributed v. U.S. Dep’t of State. They discuss the case and its implications for free speech, gun rights, and our economy. Is computer code always free speech? Is there a legitimate public interest in banning citizens from printing their own guns? See Cato’s brief here.
