FORT MYERS, Fla. -- An update to a story you first saw on WINK News.  Last week we showed you how 3D printing could revolutionize the way people make firearms.  Now a group in Texas is claiming they've already done it.

Anyone with printers at home could eventually make untraceable guns.  Now a group in Texas is claiming they've already done it.

The group in Texas is called Defense Distributed.  We told you about them last week.  On Monday, they released video of them firing a single shot from a gun created from a 3D printer.

The group is calling the gun the Liberator.  They claim all the parts needed for the gun were printed on 3D printer except for the metal firing pin which was made from a nail.

Local experts claim while printing 3D guns is possible, it poses a risk for safety.

"It probably wouldn't totally act like a hand grenade but it would probably blow your fingers off, maybe a whole hand," said Dr. Charlie Mesloh, professor, Florida Gulf Coast University.

"You definitely would run the risk of injuring yourself or maybe even killing yourself," said Mark Kemper, President and CEO, Engineering and Manufacturing Services, Tampa.

Over the weekend, New York Senator Charles Schumer said he wants to make printing 3D guns illegal.

Schumer and Representative Steve Israel are planning to try and renew the Undetectable Firearms Act.  The Act makes it illegal to make, sell, possess or ship any firearm that is not detectable by metal detectors or xray machines.

WINK News first told you last Monday, the Act has been in place since 1988 but it's set to expire at the end of 2013 and currently does not include 3D printing.
