New York 3D Printer Law Overview & Solution

At a glance

New York’s fiscal year 2027 budget, signed by Governor Kathy Hochul on May 27, 2026, made New York the first state to put 3D-printer blocking technology into law. The provisions sit in Part C of the Public Protection and General Government budget bill (S9005-C / A10005-C), enacted as Chapter 55 of the Laws of 2026. The law does two things:

It starts a process that can require blocking technology on 3D printers. A state working group decides whether blocking is technologically feasible and recommends standards. If it is feasible, the Division of Criminal Justice Services (DCJS) issues rules, and one year later 3D printers sold or delivered in New York must include compliant blocking technology.
It creates new crimes for digital gun files. Distributing “digital firearm manufacturing code” to unlicensed people, or possessing it with intent to manufacture or distribute illegally, is now a class A misdemeanor.

No printer has to include blocking technology yet. The earliest the sales requirement could apply is one year after DCJS rules, and those rules depend on the working group finding blocking feasible.

What the law requires of 3D printers

The law adds General Business Law § 396-eeee. Once it takes effect, no “person, firm, partnership, association, or corporation” may sell or deliver a three-dimensional printer in New York unless it includes blocking technology that meets the DCJS performance standards. The ban applies to anyone selling or delivering a printer, not only manufacturers.

The law defines blocking technology as:

“hardware, software, firmware, or other integrated technological measures capable of ensuring a three-dimensional printer will not proceed to print any print job unless the underlying three-dimensional printing file has been evaluated by a firearms blueprint detection algorithm and determined not to be a printing file that would produce a firearm or illegal firearm parts.”

A firearms blueprint detection algorithm is “a software service that evaluates three-dimensional printing files, whether in the form of stereolithography (STL) files or other computer aided design files or geometric code,” and flags files that would produce firearms or illegal parts. “Illegal firearm parts” covers unfinished frames or receivers, major components, and machine-gun conversion parts, including pistol converters.

A three-dimensional printer is any machine that can render an object from a digital design file using additive manufacturing, or make three-dimensional modifications to an object using subtractive manufacturing. That definition is broad enough to reach some subtractive machines, not only filament and resin printers.

The working group and the feasibility test

New Executive Law § 837-aa directs DCJS, the Department of State, and the State University of New York to convene a working group within 90 days of the law taking effect. Its members are experts in additive manufacturing, artificial intelligence and digital security, firearms regulation, public safety, consumer product safety, and other fields DCJS chooses.

Within one year of convening, the group must recommend minimum safety standards. These cover the types of blocking technology, minimum performance standards for both the blocking technology and the detection algorithms, safeguards against circumvention, and alignment with state and federal law. DCJS then has nine months to publish rules, in consultation with the Department of State.

The whole process depends on a feasibility finding:

“if the working group determines that it is not technologically feasible to require three-dimensional printers sold in the state of New York to include blocking technology, the working group shall so report, and no regulations shall be required to be promulgated pursuant to this section, until such time as the working group determines that it is technologically feasible.”

DCJS is also authorized, but not required, to build a library of firearm and illegal-part blueprint files, including scans of seized firearms, for printer manufacturers, software vendors, and experts to use. It must set safeguards against unauthorized access to and misuse of that library.

Timeline

May 27, 2026Governor signs the budget bill as Chapter 55. The blocking-technology provisions (Subpart B) take effect immediately.
Aug 25, 2026The new digital-file crimes (Subpart A) take effect. This is also the statutory deadline to convene the working group. As of October 5, 2026, we found no public announcement that it has convened.
May 31, 2027Dealers and gunsmiths may no longer sell convertible pistols, with stated exceptions.
Within 1 year of conveningWorking group recommendations due, around August 2027 if it convened on the deadline.
Within 9 months afterDCJS publishes rules and performance standards, if blocking is found feasible.
1 year after rulesThe printer sales requirement takes effect. If every step uses its full allowance, that is around mid-2029.

New crimes for digital gun files

Subpart A amends the Penal Law to define “digital firearm manufacturing code”: CAD files or other code or instructions that may be used to program a 3D printer or CNC milling machine to produce a firearm, ghost gun, unfinished frame or receiver, silencer, rapid-fire modification device, or major component. It then creates two class A misdemeanors:

Distribution (Penal Law § 265.10(11)). Knowingly selling, transferring, distributing, or otherwise providing the code to someone who does not hold both a New York gunsmith license and a federal firearms license. Exceptions cover a reasonable belief the recipient will not misuse it, transactions where neither party is in New York, and recipients with both licenses.
Possession with intent (§ 265.10(12)). Possessing the code with intent to manufacture illegal weapons, or to distribute it to a New Yorker who is prohibited from having firearms or who lacks both licenses.

Possessing a file is not a crime by itself. The offense requires the intent the statute describes. The law also adds digital firearm manufacturing code to New York’s gun-industry public-nuisance law.

Enforcement and exemptions

Attorney General. The Attorney General can seek an injunction, restitution, and preliminary relief against sales that violate the printer requirement.
Civil penalty. A “gun industry member” faces $5,000 “for each qualified product” sold in violation. How that applies to printers is unclear from the text, because printers are not listed as a “qualified product” in the related definitions.
Private right of action. Anyone damaged by a violation may sue for damages or to enforce the section.
Licensed buyers. A buyer who holds both a New York gunsmith license and a federal firearms license can buy a printer without blocking technology after the Attorney General verifies the licenses and issues written authorization.

The statute contains no privacy rules for users or print files. Its only data safeguards apply to the DCJS blueprint library.

What it means for printer makers and platforms

No standard exists yet, so no product can be certified as compliant today. The working group’s recommendations will set the bar, and the questions it has to answer are concrete: how accurately a detection algorithm must flag firearm files, how often it can wrongly block lawful prints, and how hard it must be to circumvent.

Manufacturers that sell into New York can prepare now by measuring how detection would fit their printers, firmware, and slicing software, and by contributing evidence to the working group.

Where PrintGuard fits

The law describes software that evaluates STL and other print files and flags firearm components before a job runs. That is the problem PrintGuard v1 is built to solve. It screens geometry locally, scores each file, and keeps an auditable record.

Frequently asked questions

Does New York ban 3D printers?

No. The law would require 3D printers sold or delivered in New York to include blocking technology, and only after a working group finds it feasible and DCJS publishes rules.

When do 3D printers sold in New York need blocking technology?

One year after DCJS publishes performance standards. If each step uses its full time allowance, that is around mid-2029. If the working group finds blocking not technologically feasible, the requirement does not begin until it later finds otherwise.

Is it illegal to have a 3D-printed gun file in New York?

Not by itself. It is a class A misdemeanor to distribute digital firearm manufacturing code to someone without both a New York gunsmith license and a federal firearms license, or to possess it with intent to manufacture or distribute illegally.

How is New York's law different from California AB 2047?

Both make printer sales depend on future standards. New York’s process turns on a state working group’s feasibility finding. California AB 2047 turns on whether ASTM International publishes an industry standard showing blocking is feasible; if none exists by July 1, 2029, California DOJ need not act further.
