3D-Printed Weapons & the Consequences
DesignNews ^ | 12/11/2012 | Cabe Atwell

Posted on 12/12/2012 6:32:09 AM PST by palmer

At-home 3D printing is on the rise, and what was once just a lofty promise is now a reality. More and more hobbyists are acquiring affordable printers, such as the Makerbot Replicator 2 and the RapMan Universal 3D (single/dual head) printer, to manufacture just about everything from toys to working clocks.

Some hobbyists have used these printers for fast-prototyping items that are controversial -- or even deadly. It comes as no surprise that some would attempt to replicate weapons systems (or at least parts of them) in an effort to create a fully functional gun. It's not exactly clear who was the first to fabricate a firearm using a 3D printer, but one example that has garnered global attention is "Have Blue" who designed an AR-15 lower receiver (converted to fire .22 ammunition), using a CAD file in the SolidWorks file format that is openly available from CNC Gunsmithing.

“Hey check out this gun I just printed” lol

I wouldn’t want to shoot it unless I was in a “had to” situation.

This is a perfect gun for a criminal. Dispose of and print again as needed.

This technique will get only better ~ particularly as printers learn to 'build up' the hard parts with nano particle layering.

Bet you could even build your own superior iron hydride batters with these home systems in a year or two.

Actually, it's a perfect weapon for random distribution ~ (assuming all the rough edges of design are worked out and you get a totally printed version) ~ instead of laying down a mine field of minature explosive divices, you do an arial bombardment of enemy occupied territory with these ~ hundreds of thousands of them. Your resistance forces pop up.

So they only fire half a dozen or a dozen rounds ~ you make that up in volume!

Understand that this is only the beginning of the return to medieval home industry ~ eventually you'll think real hard about something and your computer driven replicator will make it for you.

That’s what I want to know. You need steel for that and you can’t do it with a copy machine.

Some in Congress have their panties in a knot and want to renew the ban, that I believe is due to expire, on “invisible” (to X-Rays) guns that was passed when Glocks started becoming popular.

The geniuses in Congress figured that if the Glock frame was made from polymers the pound of steel that made up the slide and barrel would become invisible to X-Rays and could get past the airport screeners. I think Schumer was behind that one.

"After prototyping a small-scale model, he fabricated the full-size receiver and used it to fire 200 rounds without catastrophic failure."

200 rounds not bad for plastic.

To the BATFE, a “firearm” is the piece that gets the serial number. So you only need to make the lower receiver. All the other parts (upper receiver, barrel, trigger group, springs) can be bought over the counter with no paperwork. (Although if “printing” lower receivers becomes popular, expect some legislation changing this).

For an AR-15, the lower receiver is the serialized firearm, according to the BATFE. The receiver contains the trigger, hammer, safety, magazine and bolt lock/release. The receiver extension (buffer tube) is attached to the back of the lower receiver. The upper receiver holds the bold, barrel, and chamber. These are the parts that are exposed to high chamber pressures when a round is fired. These could still be made by forging and machining since no paper work or serial numbers are involved on these parts.

The only parts on a printed lower receiver that might need reinforcment would be the pin holes where the lower and upper receiver are joined and the threads that hold the buffer tube.

Many years ago, my father (may he rest in peace) saw the internet and saw what people were using the internet for and he said, "They will never control pornography again". Once it's just bits of data zipping around the world, then the cat is out of the bag and (like it or not) there is no way to control it short of tyrannical government that would make Hitler look like a sweetheart. Information wants to be free -- even immoral information.

3D-Printed weapons are the same thing. We just got the Second Amendment back. It may take government time to realize it, but guns are now beyond their control.

You don’t need 3D printing to build a lower receiver, just a metal working shop. The Afghans build AK-47s in very primitive conditions. And you don’t need printing to make a fully-automatic weapon, just a little work on the lower receiver of a semi-automatic weapon (NB the Afghan AK-47s again).

Standard upper, 7 inch flat-top. Only the lower receiver was printed.

The furor sounds a great deal like that over the Glock a bunch of years ago. PLASTIC GUN!!!! undetectable through xrays!!!!!!

The horror!

Actually, until (as someone has already mentioned) nano hardening or some sort of metallic matrix is incorporated, there will only be support or structural parts available with this process.

Gotta love the home rapid prototyping possibilities though!!!!!!!

I believe that you are correct. The current 3-D printing methods will develop out and offer many advantages but the concept itself will cause the development of entirely new 3-D “printing” at the nano or molecular level.

I'm not saying Trek replicators but think about what you could do...

The barrels and upper receivers can be purchased without any restrictions whatsoever — only the lower receiver is the ‘firearm’.

Yup. The quality will get better and better -- but quality isn't the key thing. There is no way to control this now. Every blog pimp in America is now the equivalent of Smith & Wesson. More than that. Think about everyone in America who currently has an HP or Lexmark printer in their home. Sure, they print paper now -- but in 10 years time, there will be 200 million Smith & Wesson corporations scattered across the land.

Every man a gunsmith. Registering guns? Tracking firearms? Ballistic testing at crime scenes? It all goes out the window.

For good or bad, the government will be TOTALLY incapable of infringing your right to keep and bear arms.

We used 3-D printers in our lab for years. Saved us a ton of money when we were developing prototypes. The material we had was a plastic or resin type. Our printer was rather small, the size of a coke machine. Big moving platform behind a window,,you could watch the item being constructed stand by strand. Our stuff would take 8-9 hours sometimes..and our parts were relatively small. That printer costs us about 45K and was considered small to medium in size. The material wasn’t too expensive but we used a lot of it up. Strange to program a machine to build a part and have the end result look like a toy. It was remarkable.

Right now, it is not difficult to make a fully automatic weapon - the Afghans do it in very primitive workshops, making AK-47s. The reason it doesn't go on too much in the US is that it is illegal and most gun people are law abiding citizens. That will discourage a lot of 3D gun builders.

However, if our law-abiding citizens lose faith in the honesty of their government and/or feel their liberty seriously threatened, all bets are off. The only problem then will be that fully-automatic weapons are very wasteful of ammo.

I agree.

Some things are surprisingly easy, if people have a good reason to do them. On the opposite end of that spectrum, your post reminds me of the scene in the first "Iron Man" movie in which the bad guy (Obadiah) has assembled a team of brilliant scientists in an effort to duplicate Tony Stark's iron man suit. The team finds the task difficult.

Brilliant scientist: We still haven't solved it yet.
Obadiah: Tony Stark did it! He did it by himself! In Afghanistan! In a cave!
Brilliant scientist: Well ... I'm not Tony Stark.

Coming soon to Kalifonia:

Anyone found guilty of possession, use or sale of 3D printers, without an approved LICENSE, shall be guilty of a CLASS A FELONY. (life in prison)

Wait and see ...............

You’re all dreamin if you think they’re going to allow this to evolve to its natural conclusion.

AND BTW, if you also think that possession of the presently unserialized parts won’t be criminalized, you’re also dreaming some more.

Y’all just don’t get it yet and I shudder to think how far it has to go before all the frogs wake up and ask “When did the $%^*$& water get so hot?”

I believe it will be some time before an entire device is printable by the least motivated class of citizen but well before, entrepreneurs will make use of the technology which will bring us to the position you've described.

Think about this a bit more: through nano construction, complex devices could be built. A virus or malware would become a program that causes your printer to create something that spies on you or attempts assassinations...hmmmm, this looks like something that would be a short story in Analog.

Your point is very valid.

The question is: at what point do the frogs wake up and decide to jump? Manufacturing in the US will not be able to compete if 3D-printers are restricted. Gun owners will see what is happening -- and at some point they will stage armed protests. The Bastille will be stormed.

I don't know what the tipping point will be, but I am sure that there will be a tipping point. I look around today and I just see so many things that "ought to be" the tipping point.

I think CW is inevitable. Elections don't count. We have the means, and we will make the political change when we decide we have to.

You know like they only had bows and arrows like only like 100 years ago and like they aren’t deadly anyway ‘cause people don’t die in the Old Western movies I’ve seen on TV.

And like guns have only been like around like you know maybe 50 years or something like that you know, that why like we’ve only had these shooting like just recently like you know and now it’s a big problem ‘cause al l these guns are around that just shoot themselves like you know…

Like I know all this like ‘casue I study the wiki and like my teachers like talk about this stuff in school and like we all agree like guns is bad, like you know dude?

Right!

As of right now this is the part of an AR that is considered the firearm:


The serialized lower receiver. Everything else is off the record on your rifle as long as you use a barrel that's at least 16 inches long.

Here’s a cool link to where a guy makes an AK receiver from a shovel blade. Not joking. Nice bit of metalwork.

http://www.northeastshooters.com/vbulletin/threads/179192-DIY-Shovel-AK-photo-tsunami-warning

Bear with it, it takes a while to get going on the receiver fab. Scroll past the intro pics to the pic of the shovel blade with the handle removed, that’s where it starts getting good.
