Public tracker for state laws and proposed laws that ban or directly restrict 3D printing in the firearms context, with a focus on:
- 3D-printed firearms
- unlicensed 3D printing of firearms or firearm components
- digital firearm manufacturing files
- CNC / additive manufacturing restrictions
- printer-level blocking or blueprint-detection proposals
Last filtered sweep: 2026-07-16.
The main working file is state-tracker.csv. It is filtered to states that have passed, or are actively trying to pass, direct 3D-printing firearm bans/restrictions.
The latest dated updates are updates/2026-07-16-sweep.md and updates/2026-07-16-new-state-sweep.md.
The plain-language state-by-state FAQ is in FAQ.md. It summarizes what each tracked state's law or proposal does and does not do.
The federal terminology reference is in federal-ghost-gun-definition.md. It explains the relationship between "ghost gun," "privately made firearm," "firearm," and "frame or receiver."
The advocacy and funding research note is in advocacy-and-funding.md. It tracks public evidence for who is sponsoring, supporting, organizing, or funding the policy push behind these bills.
The right-to-repair cross-reference is in right-to-repair-correlation.md. It compares printer-blocking legislation to repair-policy issues like software locks, firmware control, anti-circumvention, parts pairing, and owner modification.
The Physna feasibility note is in physna-feasibility.md. It evaluates public claims about geometric-search firearm blocking technology and explains why shape-matching is not the same as a reliable, universal 3D-printer safety mandate.
The cost estimate is in cost-of-implementation.md. It breaks down likely state, vendor, and consumer costs for printer-blocking mandates, including likely purchase-price increases and possible monthly compliance subscriptions.
The linked media index is in articles-and-videos.md. It collects articles, reports, hearings, videos, and commentary related to 3D-printed firearm legislation, printer-blocking mandates, Physna, and right-to-repair concerns.
The Physna financial-ties research note is in physna-financial-ties.md. It checks whether tracked lawmakers and supporters have public financial ties to Physna and distinguishes direct financial evidence from regulatory-capture concerns.
Initial sources included Everytown, Giffords, state legislature bill pages, LegiScan bill pages, and official state press releases where available. This repo should be treated as a tracking project, not legal advice.
