Philadelphia has become the first city in America to ban 3D-printed guns amid fears such bootlegged firearms could fuel a surge in violent crime.
Lawmakers of America’s fifth biggest city passed a bill on Thursday, six months after the blueprint for the 3D gun known as the Liberator was made available online by the group Defense Distributed.
