iStock/Thinkstock(WASHINGTON) — A federal judge in Seattle issued a temporary restraining order late Tuesday to stop the release of downloadable blueprints and instructions on how to build an untraceable and undetectable plastic firearm using a 3D-printer.

The nationwide order, sought by attorneys general for eight states and the District of Columbia, blocks gun-rights activist Cody Wilson and his Texas-based company, Defense Distributors, from publishing plans for a plastic gun online, which they could have done beginning Wednesday.

It comes after Senate Democrats warned the Trump administration that the firearms could end up in the wrong hands. A 3D-printed gun doesn’t require a background check, a serial number, or a gun registration.

“As of tomorrow, anyone, including criminals and terrorists can have access to blueprints for making deadly weapons with a click of a mouse,” Sen. Ed Markey, D-Mass., said Tuesday during a press conference hours before the judge’s order. “Anyone will be able to download a computer file and use a very simple process to make it possible for them to be able to make a gun.”

“It’s the ultimate gun loophole. Why buy them if you can print them at home instead?” Markey said.

“These firearms are also untraceable. They will not have a serial number for law enforcement to reference and in the case of purely plastic firearms, these firearms will be undetectable. They will pass through metal detectors without a blip, a buzz or a bell that is going off,” he went on.

For years, the State Department has argued that allowing these blueprints for 3D-printed guns to be published online would violate federal export controls because the digital codes would help facilitate the manufacturing of weapons that can be accessed freely around the globe.
