Any hope of effectively controlling firearms in the United States is dead. While politicians can continue drafting restrictive gun laws, advancements in technology and pivotal court decisions have rendered such efforts largely meaningless. Today, anyone with access to a $200 3D printer can easily manufacture firearm components. These devices, guided by downloadable computer programs, can produce a perfect frame for a semi-automatic pistol. Since polymer-framed guns like Glocks require no traditional machining, they are particularly easy to replicate. The frame of a firearm is the regulated and serialized component under federal law, but a homemade frame bypasses these regulations entirely, allowing individuals to produce guns in secret. Importantly, 3D printers are common among hobbyists and are used to make a wide variety of items, further obscuring their potential use for firearm creation. In addition to these technological advances, legal developments have further dismantled gun ...
