Feds Worried About Plastic 3D Printed Guns as Firearm Law Set To Expire

Federal law enforcement authorities are raising concerns new, futuristic 3-D printed guns made entirely out of plastic could pose a myriad of security threats across the U.S., as a law banning undetectable firearms is set to expire.

3-D industrial printers that can create plastic models and prototypes can make workable guns that can't be picked up by metal detectors, and officials say they could pose a threat to countless government institutions, schools and other buildings.
