3D-printed Firearms

[sheit]

Hello,

I've just started writing what you could call a dissertation (although much less extensive than a usual one) about 3D-printed Firearms and their implications on primarily but not only gun control.
When I chose this topic over a year ago, all that had really been developed (or that I had heard about anyway) was the Defense Distributed stuff (namely the Liberator and the AR-15 Lower Reciever).
Now, however, there seems to be quite a bit more. So far, I've seen some allegedly partially 3D-printed SKS firing test, an article about some Japanese guy who got arrested for owning 5 different 3D-printed Firearms,
at least two of which could fire lethal ammunition (aka work, if I understood it correctly) and I've seen some 3D-printed revolver that is named after the Japanese guy.

What are all these new weapons, where did they come from, where can I find some concrete information on them? I seemingly can't even find out who developed most of them.

So, can someone who has researched this more thoroughly than I have, or even someone who just happens to have stumbled upon some information (anyone who knows anything on this topic really) post as much information as possible?
It would help me out a great deal (no, seriously, my graduation is pretty much dependant on this). Thanks in advance.

Edit:
In case it wasn't clear enough from the post above: I have no interest in developing or printing any sort of weaponry, I don't even need the blueprints, I am just writing a dissertation!

Careful on what you print. You do realiize that by publishing intent to create the government can start taking an interest in whether they can come seize your property because you want to violate federal laws. No I dont know what federal laws. Yet the last American that I heard of creating a fire arm lost his printers and computers. From what you have written you are expressing intent of making something that has been deemed illegal. The reason that you dont see it anywhere online is because of it being illegal. I suggest you avoid doing anything other than magazines or receiver stocks. Otherwise we will be reading about you as well in the news.

Just my 2 pennies.

As should be made very clear by the edit I've just added to the original post, I have no intention of developing or printing firearms, I am just writing a dissertation about them.

What Curious Aardvark said, but for every UK, read Australia.

And the media hype about 3D printed guns is just that, hype. Actually it's ill-informed, grab-at-a-straw, unresearched bunkum. Just like every light airplane that is involved in a flying incident is a Cessna, not matter what the truth might be.

A dissertation, essay, or whatever about the 3D Printing of guns is best suited for submission as an English Literature work of fiction. You'll get better grades and your work will make more sense.

He's writing ABOUT 3d printed firearms, not making.

Thankyou for clarifying that point. I too will print parts of a gun yet if some one is hiring me to make the firing end I will be calling the FBI to let them know what a customer wants me to do. I have no desire to bend the law, parts and pieces of hard to find items are great. Otherwise no.

As to what has become of the subect matter, from what I understand, when people got arrested. Some legislation was put in effect, what that legislation was I cant say (as I dont have that information either). There was a vid that PBS did that was on Netflix about the fellow whom turned a blind eye to the possibility of prosecution. It was near the end of the narration of the show that had the info as to why little info will be found online about printable fire arms.

Good luck on your dissertation.

It sounds like you dont know anything about firearms or additive manufacturing, yet you're going to try and write a dissertation about both? You might want to choose a different topic. I don’t say that to be a dick, but quality research typically doesn’t start out with multiple fields you are ignorant in. As an electrical engineer, my graduate thesis wasn’t about thermal load transfers during metallic alloy forging…

However, let me at least start you off, if you want to continue. Especially seeing as this topic is “the new hotness,” and that every article it I’ve ever read gets it wrong. When infact it is much todo about nothing.

First off, in almost every US state there is absolutely ZERO illegal about manufacturing a firearm for personal use. There might be local laws infringing upon this (aka DC), but basically everywhere else it has been legal since the founding of the nation. So, I will speak in generalities because I have no clue what your local laws are.

The biggest stipulations are complying with the Gun Control Act of ‘68 and the National Firearms Act of ‘34. In short, you cant manufacture a short barreled rifle/shotgun or sound suppressor without first getting an “NFA stamp” after an FBI background check and you cant manufacture a new machine gun. After 1986 new machine guns could not be submitted for approval by individuals. Provided your state allows for it, machine guns are perfectly legal to own provided you get all the paperwork and clear the FBI checks.

For example, I can go down to Ace hardware (or lowes or home depot, etc) and spend 10 bucks on a 2x4, steel piping and fittings and create a gun. Provided it complies with the above, that is perfectly legal and has always been legal to do. Or if you have a CNC you could have simply milled a firearms receiver (the part that houses the barrel, trigger group, etc) out of a chunk of aluminum, steel, or a hard polymer. CNCs have been doing this for literally decades…

So right off the bat; manufacturing, assuming compliance with the law, has been around since basically the invention of the gun. It’s also as simple as 10 bucks and 30 minutes at Home Depot. Hell, most people already have enough stuff laying around their house to make multiple legal firearms.

Now that you have a background on how simple it is to make a gun and that it’s ALWAYS been legal to do so, lets move onto additive manufacturing.

Quite simply, it’s the reverse of subtractive manufacturing. It does the opposite of that CNC mill. There is the misconception that you can download a file and the printer magically pops out a part. That’s as true as the CNC magically making a part from a chunk of aluminum. It’s really a trade, the amount of work that goes into making and being able to print quality parts. However with the plastic printers, even when printing with nylons, they are much more limited than CNCs. Even with 100% infill, printers are looking at about ~40-60% of the strength had that same material been injection molded.

This means that the only viable plastic firearms parts are low pressure/strength parts. If you’ve done any research at all yet, you would know that a lot of these “full” printed guns use metal barrel/chamber inserts or a printed super thick to withstand the chamber pressure. Elsewise they very quickly fatigue and fail.

The elephant in the room. The media likes to push the “big scary” aspect of this. Does anyone seriously think the rocket surgeon sticking up liquor stores is going to invest thousands in a 3d printer, spend the vast amount of time it takes to use it right, just to make a single shot firearm? Or will they spend 10 bucks at home depot and make a zipgun? It’s fear mongering and that’s all it is. A new technology, that will be super disruptive to manufacturing, that the government doesn’t have its claws in yet. Big business knows the “ban something that people could use at home to print replacement parts” wont fly. So the tactic is “let’s scare the shit out of them,” that way they can regulate and tax it. It’s about control, not safety. It's about taxation, not danger.

outofstep, not sure what's your issue is. The guy never claimed he's an expert on anything nor claiming any sides of the argument; he's just asking for resources for his paperwork.

I dont have an issue. If you read my reply, I just dropped alot of info for him to use.

Are you upset because I used the word ignorant? Look up it's actual meaning, its not a "bad word" or an insult. Hence my IMMEDIATE example of saying me writing about a mechanical engineering issue would be from a place of ignorance. OP said he's working on a dissertation, not some simple paper. Those are worlds apart. Dissertations are typically written for your PhD. If dude is actually writing a dissertation, but doesn't know the 1st thing about either of the topics... he's not on the right track.

If that got you upset, you need to re-calibrate your dander meter.

A) Dissertation is also for some bachelor and master degrees, not just PHD. Depending on the college, it's often called a thesis; but some do distinguish the two terminology as different. B) None of what you said are not sources of what he was originally asking, he cannot source what some guy "dropped alot of info" on a forum.
