This bill matters because it addresses a growing concern about how new technology, specifically 3D printing, could make it easier for people to get firearms that are untraceable and potentially undetectable by metal detectors. If this bill becomes law, it would be harder for individuals to find and use digital plans to 3D print guns, which could make it more difficult for prohibited individuals (like felons or domestic abusers) to acquire firearms without background checks.

If this bill does not become law, the online distribution of these 3D printer plans for firearms would continue to be legal under federal law. This means that individuals could still freely access and use these plans to create firearms that lack serial numbers, making them nearly impossible for law enforcement to trace if they are used in a crime, and potentially making plastic guns that bypass security checkpoints. Voters should care because it impacts gun safety regulations, the traceability of firearms, and the ability of law enforcement to investigate gun crimes.
