Official summary
Abstract published by the legislature (via Open States). Text as published by the legislature; reproduced verbatim.
This Act requires that all 3D printers sold or delivered in the State be equipped with blocking technology that prevents 3D printers from being used to create firearms or firearm parts. All 3D printer manufacturers must submit to the Attorney General a sworn attestation that they have equipped a make and model with blocking technology in order for sales and deliveries of the make and model to be lawful in the State. Before the ban goes into effect, this Act directs the Attorney General to create a working group that will recommend the minimum safety standards a 3D printer’s blocking technology must meet in order to comply with the requirements of this Act. The working group must also determine the feasibility of requiring 3D printers include blocking technology. If the working group determines the requirement is feasible, the Attorney General is authorized to do the following: (1) Promulgate rules and regulations establishing performance standards for 3D printing blocking technology. (2) Facilitate the creation of a library that securely holds 3D files that are banned under this Act to be used in the creation of blocking technology. The prohibition on the selling or delivery of any 3D printer not equipped with blocking technology is effective 6 months after notice by the Attorney General is published in the Register of Regulations that final regulations to implement this Act have been adopted.
