In 2013, an activist in Texas with anarchist philosophical views made headlines by creating a 3-D-printed handgun called the Liberator and successfully firing it at a private range. The maker was careful to include a metal part to comply with a federal ban on plastic handguns that might slip through airport security. Nevertheless, the Liberator seemed intended to demonstrate the ultimate futility of government-imposed gun control, in a future in which it would be easy to distribute blueprints for DIY weapons via the Internet [source: Silverman].
Indeed, just a year later, authorities in Japan—a country with restrictive gun control laws—arrested a 27-year-old man for allegedly possessing five plastic handguns, created from plans he had downloaded off the Internet [source: Kravets]. Wired reported in 2014 that DIY gun makers had learned to use 3-D printing to create "powerful, military-grade firearms, and that it would be "only a matter of time until fully-printed guns are equally durable and deadly" as those made in conventional factories.
