A U.S. judge on Friday rejected a last-ditch effort by gun control groups to block the Trump administration from allowing the public to download blueprints for 3-D printable guns, declining to intervene just days before the designs are expected to go online.

If they ever do rule for the Brady Bunch, all the designer has to do is preface every step with =>
“WARNING! DO NOT DO THE FOLLOWING...”
I have a printer in the garage. Who wants a gun?
Titanium 3D printing is now available. Print a firearm that won’t rust and never wear out. Sounds good to me.
What would you make with it?
What can you make with your printer?
Lol. How do you stop something from getting on the web? Just fly to the Caymans and post it.
Anything plastic. Honestly I think it would explode
My understanding is that viable designs for 3D printed guns have been on the dark web for years.
Yeah. They’re clunky. But the important thing here is Yuge.
This establishes a right to at least Acquire without a 4473.
Give it time to percolate and this will establish precedent making it much harder to deny 2A rights at every level.
I've downloaded some in the past. And haven't bothered printing one on my 3D printers. Not worth the effort.
With the proper tools, a machinist can produce an excellent gun. Regular 3D printers cannot. They may function, but are inferior in every way to handguns readily available everywhere. It's a non-issue regarding the security of the country.
There are various materials available for 3D printing. On basic home models, PLA or ABS plastics would not hold up and would quickly break down under heat and pressure. Nylon filaments are much stronger. A mix of metal components along with nylon printed parts would work, and probably hold up under repeated firing. But not as well as a machined weapon tooled with all metal components. Stick to non-3D printed weapons, it's much safer (and easier to obtain).
The lower receiver of an AR-15 is the serial numbered part that the BATF considers to be a firearm. It and ALL of the other components, to include the upper receiver, the barrel, the fire control group and buffer tube are considered parts that are not subject to federal regulation. The lower receiver bears little of the actual stresses involved in launching a bullet down the barrel. It is primarily a platform to mount the upper receiver, magazine, fire control group and trigger, buffer tube/recoil spring,and magazine. The barrel, bolt/bolt carrier and barrel extension mounted to the upper receiver bear and contain all the actual pressures generated when the cartridge is fired.
That is why the lower and upper receivers can be formed from lightweight aluminum castings, forgings, or plastic moldings, with no fear of exploding as long has the barrel, barrel extension bolt/bolt carrier and chamber are soundly constructed of firearm quality steel.
But, but, but.... I saw one in a movie once that looked like a Sig.
I have 3D-printed various tools and items for myself. And plastic items are, well, plastic and don't always hold up. I've had better success by using nylon filament on my 3D printers, very strong but it is difficult to work with in making it look good and fit well. ABS is easy to clean up and polish (via acetone vapor bathing) but simply is not strong under pressure and repeated use, warps and cracks easily. I have found 3D printing very useful for making items that are difficult to obtain otherwise, such as adapters for hoses, special clamps, knobs, electronics cases, etc. For examples I made a special mount plate for my cameras and a tripod, and cases for LED arrays with batteries and controller. But guns, no I don't think I would try, as I already have what I need.
These hoplophobes are ignorant. Those designs are already available online. Check my blog and thousands of other sites. Been there since May 2013.
Given what they are, There is a market for complex machined parts, that can be 3D pinter for a fraction of the price of machining them, things such as propeller for boats, impeller assemblies for pumps, and a whole assortment of aerospace compnents.
I could run a side business out of my garage, and do very well for myself.
