SECTION 1. SHORT TITLE. 
This Act may be cited as the ‘‘3D Printed Gun Safety 
Act of 2019’’. 
SEC. 2. FINDINGS. 
Congress finds the following: 
(1) Three dimensional, or ‘‘3D’’ printing, in-
volves the programming of a 3D printing machine 
with a computer file that provides the schematics for 
the item to be printed. 
(2) Recent technological developments have al-
lowed for the 3D printing of firearms and firearm 
parts, including parts made out of plastic, by unli-
censed individuals in possession of relatively inexpen-
sive 3D printers. 
(3) Because 3D printing allows individuals to 
make their own firearms out of plastic, they may be 
able to evade detection by metal detectors at security 
checkpoints, increasing the risk that a firearm will 
be used to perpetrate violence on an airplane or 
other area where people congregate. 
(4) The availability of online schematics for the 
3D printing of firearms and firearm parts increases 
the risk that dangerous people, including felons, do-
mestic abusers, and other people prohibited from 
possessing firearms under Federal law, will obtain a 
firearm through 3D printing.

(5) On June 7, 2013, an assailant used a gun 
he had constructed by himself to kill his father, 
brother, and 3 other people at Santa Monica College 
in California. The person had failed a background 
check when he tried to purchase a gun from a li-
censed gun dealer. The gun he used was made from 
an unfinished AR–15-style receiver, similar to a re-
ceiver that can now be made with a 3D printer. 
(6) Firearms tracing is a powerful investigative 
tool. When law enforcement agencies recover fire-
arms that have been used in crimes, the agencies 
work with the Bureau of Alcohol, Tobacco, Fire-
arms, and Explosives to trace these firearms to their 
first retail purchaser. The agencies can use that in-
formation to investigate and solve the crimes. In 
2017 alone, the Bureau of Alcohol, Tobacco, Fire-
arms, and Explosives conducted 408,000 traces. 
(7) Firearms tracing depends on the ability to 
identify firearms based on their serial number. Tra-
ditionally, when a firearm is manufactured domesti-
cally or imported from abroad, it is engraved with 
a serial number and markings that identify the man-
ufacturer or importer, make, model, and caliber, and 
are unique to the firearm. Firearms made by unli-
