San Diego County jumped into California’s sprawling ghost gun fight this week, suing a 3-D printing filament manufacturer it says hocks material for homespun firearms in violation of state law.
Working with the Giffords Law Center, the county counsel sued manufacturer Polymaker, alleging the company made a “strategic business choice” to market and sell 3-D printer filament to Californians for the express purpose of building illegal weapons. The polymer filament is sold in spools that feed into 3-D printers, allowing the devices to form designs created by their owners.
The problem is that, legally speaking, the lower receiver is the gun. So you can buy all the other parts online with no background check etc.
A person with a machine shop and knowledge on how to use it could also do this
My biggest problem with all these attacks on 3d printing is that what you are talking about is completely legal as far as I am aware. There are tons of places online that sell partial receiver blanks that require the buyer to do the last few bits of machining and turn a “block of metal” into a “gun”, legally speaking. It is currently completely legal for an individual in the US to build a gun without telling anyone about it for personal use so long as the final result does not run afoul of ant NFA rules (like automatic fire, length of shotgun, caliber size, etc.). They don’t start doing anything illegal until they sell them, or even give them away (again, assuming they meet all of the NFA rules - obviously someone making themselves a gun has a high risk of running foul of the myriad of rules here, but the end result has to be evaluated to determine if they broke the law or not).
So all of these are just using gun terror as an attack vector against 3d printing in general. Just like the “think of the children” campaigns all over the world that are really just about stripping us of privacy and security. The guns aren’t the real problem and neither are the kids. A free, private, and secure populace is the problem.
I am not advocating that people build their own guns. I am not a lawyer. I advise anyone go learn your local laws and discuss with actual legal counsel before choosing to attempt anything that could be against federal firearm law. kthx
