Here comes 3D printed ammo!

Fresh on the heels of the federal government shutting down 3d printed gun manufacturer Defense Distributed comes the news that manufacturers are now printing ammunition. A Solidoodle 3D printer was used by Jeff Heeszel and Tony Griffy to make shotgun ammo. Griffy designed the shells using CAD to make the plans for the shotgun shells and after printing them out, filled them with lead to complete the project. How will the government react to this new marvel of engineering?
