The guys printing gun parts in Texas are licensed and regulated by the BATF. Good luck buying from them without the feds knowing. You will pay more than for a metal gun so unless you're planning on stealthing a metal detector, why buy plastic that doesn't last?
You don't have to own a high-end 3-D printer. There are plenty of online service that will print your design and ship to you. So it is more or less like anyone with access to a design file and a credit card can get the parts.
This whole fixation with high tech methods to do what low tech has done before as if it's new kind of amazes me. Don't they teach shop in school any more? Or just how to shop?
The printing service may be unaware of what's printed so how do they decide if they are printing an article that might be illegal in the customer's country. Your illegal argument is not going to stop things being printed out. Anyway the US laws don't apply overseas and lots of manufacturing happens outside this country. I was just trying to make a point that YOU don't have to own an expensive 3-D printer to print stuff in quality. I've been getting laser cut stuff since 3 years ago and never have seen a laser cutter. I doubt the service providers are fully aware what exact things I have been ordering.
John Zawahri, the 23-year-old Santa Monica spree killer, tried to buy a gun in 2011 but was denied by the Justice Department for unknown reasons. So Zawahri, who suffered from mental illness, circumvented that firewall by building his own AR-15 semi-automatic rifle using parts he bought from various sources around the country.CBS News with Scott Pelley reported Friday that the sale of most gun parts online is not regulated, except for one critical component: the lower receiver, which holds the mechanical parts of the gun, such as the trigger. A background check is required to buy one, but Zawahri got around that by buying a partially-completed lower receiver and modifying it, something gun enthusiasts call 80-percent guns. The resulting gun, which fired .223-caliber ammunition, was untraceable.
Not just gun parts sales online are not regulated, lots of things sold online are not regulated as they are when they are sold in stores. I honestly don't know how these things can be regulated with the sheer volume and different sellers online. Tax is not even charged for lots of these sales although where I live there is a required use tax if electronics are purchased online. Honest citizens are supposed to pay them somehow though LOL
Still trying to make my point here "you don't need expensive 3-D printer to print quality parts", period. You are assuming every piece of 3-D printed part gets scrutinized at the print house so illegal or unsafe parts are not made. That is naive. Yeah, the vested interest is there. But no, there is no time to act on that interest and police every part they make. Notice, my point has not mentioned whether parts are legal. I was countering someone else argument that you need to be made of money to have good 3-D printed parts. You don't.
