At least 16 states have now restricted 3D-printed firearms, seven in 2026 alone, and the groups fighting back just lost a key federal court ruling with a potential Supreme Court showdown ahead.
New York Governor Kathy Hochul signed the latest measure on May 27, a law that criminalizes possession of digital gun-design files by unlicensed individuals and requires 3D printers to be equipped with technology that blocks firearm printing. The law takes effect this month. Six other states passed major restrictions earlier this year, bringing the tally to 16 states with laws targeting what critics call ghost guns.
The laws vary in how far they reach. Virginia banned the manufacture, sale, or possession of any unserialized firearm, including unfinished frames and receivers. Washington's governor signed HB 2320 on March 24, barring private use of 3D printers to manufacture firearms and prohibiting possession of digital instruction files for firearm components. Maine required serial numbers on all firearms, 3D-printed or not. New Jersey's law, on the books since 2018 and now at the center of the biggest legal battle, criminalizes distribution of digital firearm instructions to anyone without a federal firearms license.
The NRA has opposed each measure. When Washington signed its ban, NRA State Director Aoibheann Cline said digital firearm codes are "speech protected by the First Amendment." The NRA-ILA flagged New York's law the same way, arguing that criminalizing mere possession of a digital file sets a constitutional precedent that other Democratic-led states are already treating as a model.
In February, the U.S. Court of Appeals for the Third Circuit handed gun rights advocates a clear setback, affirming dismissal of all constitutional challenges to New Jersey's law in Defense Distributed v. Attorney General of New Jersey. The plaintiffs were Defense Distributed, the Texas company that pioneered 3D-gun blueprints, and the Second Amendment Foundation. Writing for a three-judge panel, Judge Cheryl Krause held that "purely functional code with no actual or intended expressive use" falls outside First Amendment protection. The Second Amendment claim died separately: the court found the plaintiffs had not alleged they were actually prevented from printing a firearm, leaving the challenge without a concrete injury to adjudicate.
The Second Amendment Foundation petitioned for en banc rehearing in March. The full Third Circuit declined in April, according to the Jersey Vindicator. A petition to the Supreme Court is the logical next step, and SAF has signaled that is the plan. Whether the justices take the case is an open question. The court has shown appetite for Second Amendment challenges since its Bruen decision in 2022, but the 3D-printing cases present a knot of First Amendment speech questions alongside the gun rights arguments, and the court may wait for a cleaner vehicle before wading in.
New York's law is almost certain to generate fresh litigation. Hochul's office acknowledged that the gun-file-blocking technology the law requires does not yet exist at commercial scale, creating a working group with one year to study its feasibility before the printer mandate takes effect. Critics, including several digital-rights organizations, say the provision is drafted broadly enough to reach lawful speech far beyond any plausible ghost-gun concern.
Federal Bill and What Comes Next
In Congress, Representative Jared Moskowitz of Florida and Senator Ed Markey of Massachusetts reintroduced the 3D Printed Gun Safety Act of 2025, H.R. 4143 in the House and S. 2165 in the Senate. The bill would make it a federal crime to share online files that direct a 3D printer to produce a firearm or receiver. It was referred to committee in June 2025 and has not moved, with three Democratic cosponsors and no Republican support, making passage in a Republican-controlled Congress unlikely.
That leaves the fight in the states and the courts. The Third Circuit's ruling now functions as a green light for blue-state legislatures: if federal circuits will not block these laws, the expansion can continue. What stops it is either a Supreme Court decision drawing a firm line or a shift in which party controls those statehouses. SAF's challenge to New Jersey's statute, now pointed toward the high court, may be the case that forces that answer.
