Government fight against sharing 3D printed gun blueprints will be an uphill battle – Amidst the national conversation over gun control, there lies a particular controversy as to whether or not blueprints for 3D printed guns should be legal. However, according to a new proposal from the State Department, distribution of digital blueprints for 3D printable guns may be made illegal. However, Defense Distributed, a group responsible for the 3D printed gun known as the “Liberator,” is fighting back, saying the proposal violates the First Amendment of the United States Constitution.
