What it does
This bill makes it illegal to distribute computer files or code over the internet that can program a 3D printer to manufacture firearms or firearm parts. The bill targets online distribution of 3D gun blueprints to prevent unlicensed individuals—including those prohibited from owning guns—from making untraceable, undetectable firearms that evade law enforcement tracing and metal detectors.
Why we flagged it
The bill directly addresses a public safety threat—untraceable 3D-printed firearms—by restricting the distribution mechanism (online code) that enables their manufacture. The operative mechanism is a narrow prohibition on a specific form of distribution, not a broad regulatory overhaul.
What the text implies
- The bill's scope is limited to internet/web distribution; it does not prohibit in-person sharing of files, physical blueprints, or possession of CAD files for personal use, creating a potential enforcement gap.
- Defining 'code that can automatically program' a 3D printer may require ongoing regulatory interpretation as technology evolves; ambiguity could lead to over-enforcement or under-enforcement.
- The bill does not address 3D printers themselves or the underlying technology, only the distribution of instructions—manufacturers and sellers of 3D printers remain unaffected.
- Enforcement depends on identifying and prosecuting distributors; the bill does not fund law enforcement resources or establish new investigative tools, potentially limiting practical impact.

Who it affects
Ordinary citizens benefit from reduced availability of untraceable firearms used in crimes, improved law enforcement investigative capacity, and reduced risk of gun violence at public venues. The restriction targets only the distribution mechanism (online code), not lawful firearm ownership or possession by licensed individuals.
