Bill > HR4143

This bill seeks to prohibit the online distribution of digital instructions (such as Computer Aided Design files) that can be used to 3D print firearms or complete unfinished firearm frames or receivers. The legislation is motivated by several key concerns, including the potential for untraceable and undetectable plastic firearms that could bypass metal detectors, the risk of individuals prohibited from owning firearms obtaining weapons through 3D printing, and the challenges law enforcement faces in tracing such weapons due to their lack of serial numbers. The bill highlights specific instances of gun violence and trafficking, including a 2013 shooting in Santa Monica and data from the Bureau of Alcohol, Tobacco, Firearms and Explosives showing significant numbers of traced and trafficked firearms. By making it illegal to distribute these digital blueprints online, the bill aims to combat what it views as a significant threat to public safety and national security, while explicitly stating that its intent is not to infringe on First Amendment rights of computer programmers but to prevent the creation of dangerous, untraceable weapons.
