New York is part of a multi-state lawsuit challenging President Donald Trump's administration over allowing 3-D printed gun files to be made available on the Internet. 

In all, 20 states are suing over the availability of the plans to manufacture the firearms.

“These 3D-printed weapons are unregistered, untraceable, and, in many cases, undetectable," said New York State Attorney General Letitia James. "While the president and his administration know these homemade weapons pose an imminent threat, he continues to cater to the gun lobby — risking the lives of millions of Americans. We’re filing this lawsuit to stop the Trump administration from further facilitating the spread of gun violence at our schools, our offices, and our places of worship.”

Beyond the availability of the gun files, the concern from some gun control advocates as well as law enforcement is a safety factor: The guns are manufactured with plastic materials that can be untraceable in a metal detector. 

Gov. Andrew Cuomo last July signed a bill banning 3-D printed guns in New York.
