The US government has extended a ban on 3D plastic guns since they might end up in the wrong hands. The introduction of 3D printers has made the manufacture of plastic guns a reality and hence the law has to step in to restore some order.
Congress voted on the extension of a law that stated that plastic guns must have a metal component. That was so that they could be spotted by metal detectors. The Democrats wanted an all-inclusive law that virtually banned all 3D printed plastic guns since they were a public hazard.

But ultimately only the presence of a metal component in the plastic gun was to be the writ of the law. This may be due to a large scale opposition to any interference of the government by gun and rifle associations spread across America. Still something was better than nothing.
The Undetectable Firearms Act was originally passed under President Reagan’s administrative career. However, it is expiring soon. To extend it is the goal for now. The proviso is that the weapons need to have metallic components that are easily visible under X-Ray machines and metal detectors. The Republicans are opposing efforts by Democrats to make the law even more stringent.
And, of course, many gun lobbies have said that you can’t control what is essentially available on the Internet and can be manufactured using a 3D printer. The first such weapon was a gun made by a man in Texas some time ago. Called the “Liberator”, it worked as well as a normal gun would. It made the public apprehensive regarding weapons being easily created by criminals in their own homes.
