Man known as 'Dr. Death' sentenced to 3 years in prison for selling 3D-printed gun parts

Daniel Crowninshield from California used the technology to illegally build and sell parts for AR-15 rifles

A man known online as "Dr Death" has been sentenced to three-and-a-half years in prison for making and selling gun parts online, as well as owning an unlicensed rifle.
Daniel Crowninshield, 54, from Sacramento in California, operated an illegal firearms manufacturing business out of a metal shop in the city.
Using 3D printing and a computer numerically controlled (CNC) mill, he would manufacture parts for AR-15 rifles to "customers with unknown backgrounds."
Among other things, Crowninshield would create a "lower receiver" which is the part of the rifle holding the hammer, bolt and firing mechanism that combines with a trigger and firing pin. These can cost up to $300 (£241) when bought legally.

In California, an individual can manufacturer a firearm for personal use (without a serial number) providing it is not sold or passed on to a third party. Crowninshield pleaded guilty to the charges last year in exchange for prosecutors dropping other charges.
In sentencing Crowninshield, U.S. District Judge Troy L. Nunley referred to his actions as a “brazen attempt to circumvent the law”.
U.S. Attorney Talbert stated: “The unregulated manufacture and sale of high-capacity firearms is a serious threat to public safety. We will continue to investigate and prosecute unlicensed gun dealers who circumvent the law.”
Crowninshield would regularly advertise his services online in several gun enthusiast forums where he used the "Dr. Death" moniker.
