3-D printing prompts US House votes to renew prohibition on all plastic guns

Undetectable Firearms Act to extend the 25-year prohibition, but guns would be legal with a piece of metal in or on it.

WASHINGTON — The US House of Representatives voted Dec. 3 to renew a 25-year-old prohibition against firearms that can evade metal detectors and X-ray machines just as 3-D printers are increasingly able to produce plastic weapons.

On a voice vote, the House passed a bill extending the Undetectable Firearms Act for another decade.

The Senate is expected to act on the legislation when it returns from a two-week holiday recess Dec. 9, a day before the current law expires.

Sen. Charles Schumer, a leading Democrat, said he and others will try then to add a new requirement that at least one component of the firing mechanism contain enough metal to be detectable in a magnetometer and also be undetachable.

But with the National Rifle Association opposed to any change in the statute and many Democrats eager to avoid a new fight over gun controls going into an election year, the Senate is more likely to just pass the House version unamended. The House bill only requires that a plastic gun have some piece of metal in or on it, but it can be removable and doesn’t have to be used to fire the weapon.

“The House bill is better than nothing, but not by much,” Schumer said. “…It’s certainly not enough.”

Schumer said plastic guns were “the thing of science fiction” when the ban was first passed in 1988 but such weapons are now a worrisome reality.

Brian Malte, a director of the Brady Campaign to Prevent Gun Violence, said his group’s worries about the availability of plastic guns are “no reason to hold up renewal.”

The use of 3-D printers to manufacture guns received heightened attention in May when Cody Wilson, then a University of Texas law student, posted blueprints online for using the printers to make the Liberator pistol, which he says he designed. Wilson, founder of Defence Distributed, a non-profit that advocates the free distribution of information on 3-D printed weapons, was ordered by the State Department to take down the instructions after two days because of allegedly violating arms export controls, he said.

By then, the plans had already been downloaded more than 100,000 times and they remain available on file-sharing websites, he said.

“If you want to do this, it’s plainly obvious there’s no one standing between you, your computer and your 3-D printer. Anyone can make this gun,” Wilson said.

But printing a gun isn’t cheap. According to the Bureau of Alcohol, Tobacco, Firearms and Explosives said 3-D printers can cost anywhere from $1,000 to $500,000, though they can be rented. A traditional handgun can cost far less.

It’s also unclear how effective such a gun can be.

ATF tested two plastic guns from different plastics earlier this year, and one of the weapons exploded when it was fired. The second one shot off eight rounds before ATF stopped the test.

Among the chief concerns from law enforcement and law makers has been that a 3-D printed gun, made of plastic or other materials, could be easily slipped through metal detector at a courthouse or other such facilities.

New technologies being used at airports, including backscatter X-ray machines, are designed to detect non-metallic anomalies, such as liquids and potentially plastic guns.

While the NRA didn’t oppose extending the current law, it has opposed expanding it, including applying the law “to magazines, gun parts, or the development of new technologies.”
