The World's First 3D-Printed Gun
MrSeb writes "An American gunsmith has become the first person to construct and shoot a pistol partly made out of plastic, 3D-printed parts. The creator, who goes by the name HaveBlue and is an AR-15/M16 enthusiast, has reportedly fired 200 rounds with his part-plastic pistol without any sign of wear and tear. HaveBlue's custom creation is a .22-caliber pistol, formed from a 3D-printed AR-15 (M16) lower receiver, and a normal, commercial upper. In other words, the main body of the gun is plastic, while the chamber — where the bullets are actually struck — is solid metal. ... While this pistol obviously wasn't created from scratch using a 3D printer, the interesting thing is that the lower receiver — in a legal sense at least — is what actually constitutes a firearm. This means that people without gun licenses — or people who have had their licenses revoked — could print their own lower receiver and build a complete, off-the-books gun." Here come the illegal shapes. Note that the legal fiction of receiver-as-firearm is true in the U.S., but may not be in other jurisdictions, and that no gun license is required in most of the U.S. to purchase or possess a semi-automatic weapon.
Who will they blame when some nut-job goes postal with one of these illegal shapes?
Will they ban 3D Printers?
More 3D printing wankery. When can this fad die already??

The first printed product - a gun. Ugh.
It's no less illegal than making one out of metal the old fashion way, it just might be easier, assuming you have access to a 3D printer.
While the lower receiver is legally considered to be the serialized firearm it is fairly simple part. Folks have been making them on CNC machines for years. The metal upper receiver is much more difficult to manufacture and required precision metal machining. You need both to have a functional weapon. Without the upper, the lower is completely and utterly useless.
Eagles may soar, but weasels don't get sucked into jet engines.
I was wondering how long until someone could circumvent the law with a 3-D printer.

I'd like to be the first to say:
Way to fuck it up for the rest of us.
The apparent amazement about the "plastic" pistol is a bit baffling. I mean come on.
And as far as concern over someone who can not lawfully own a gun using a 3d printer to manufacture a weapon, really? For a very small amount of money pretty much anyone who wants can go buy a gun on the street. For slightly more money they can purchase a totally legal gun through the classifieds or a gun show.
All you need is a block of aluminum and a CNC machine to do the same thing.
Exactly. Anyone with access to milling equipment could mill their own lower reciever, assuming they knew the plans. Then they would still have to purchase the upper, the trigger assembly, and other parts. It's not really any different, and with the ability to mill a real receiver, they could make a firearm that can actuall handle .223/.308 rounds.
Or, you know, they could save themselves all of this time and trouble and just go to one of the myriad of websites that allow people to get in touch with others looking to buy or sell firearms. I visit one myself regularly that is part of the forums of an outdoor website dedicatedto my state, and I have even sold a firearm through it. All perfectly legal, with no documentation of transfer of ownership. And on this website alone there are often several AR- and AK- type rifles for sale, anywhere from $400-$1000. This development adds nothing to the equation.
The only thing necessary for evil to triumph is for it to be pitted against a slightly greater evil
No gun license required? Why would anyone need a license to exercise a right guaranteed by the law of the land? Do you need a license to vote? Do you need a license to be safe from being enslaved? Do you need a license to own a printing press and open a newspaper? I'm totally lost here. What sort of brain structure causes this mental vomit to occur?
Shutting down free speech with violence isn't fighting fascism. It IS fascism!
That's just an illegal custom firearm. The AR-15 has a split receiver design and the lower is serialized and constitutes the firearm. By fabricating the lower receiver this gunsmith just made a new custom firearm (legal), but did not serialize it (illegal). Also a crappy plastic gun.
A synthetic AR-15 lower receiver is nothing new, printing one yourself is however. Is it dangerous? Yeah kinda, unless you a printing with a rather high strength polymer. Is it illegal? Not if you follow the BATF guidelines. Hobby machinists have been milling them from aluminum for ages. You can buy all sorts of jigs and receiver blanks. If you were to say start manufacturing lower receivers, or do not qualify to legally own them and get caught the penalties are very severe. Also as anyone who builds their own AR-15s will tell you, certain parts are in very high demand, you may wait weeks to months for something simple to complete your build. So I wouldn't worry about somebody building a ton of "off books" rifles any time soon.
You can now literally download them and "print" the parts. (Or the local black market dealer can do it.) Outlawing guns is now more pointless than outlawing weed or cocaine, and will fail harder.

I can make a gun with a wide range of tools. How is this fundamentally different then a CNC mill?
"Have you ever thought about just turning off the TV, sitting down with your kids, and hitting them?"
the accomplishment from an engineering viewpoint (everyone working with 3D printing materials knows what I'm talking about), there is two things that came to my mind when reading these news: 1. What makes self-made weapons made with 3D printer more dangerous than those made will e.g. a CNC machine and 2. The last thing that we need is another way to make more guns..
.22 is not big enough, I'll take a penile extension instead.
In fact, a fair few are made almost entirely of plastics and ceramics. One such example is the GLOCK 17 "Parabellum". This isn't truly an all-ceramic gun (and there is no commercially available firearm that can get past a metal detector so forget the Die Hard references!), since the barrel and hammer spring need to be highly heat resistant and hard wearing - no ceramic or plastic can withstand the stresses of being fired through or repeatedly compressed quite like tenifer steel. Therefore only the frame and certain nonmoving or low stress parts (stock, trigger mechanism, sear assembly, sights, lower receiver, slide, chamber and ejector) are plastic or ceramic. This is done only to save weight, and has made the Parabellum a very popular sidearm for Government and private security contractors in Israel particularly, where they outsell any other firearm.

3d printers can cost a LOT less than a CNC, both for purchase and continued operation.
When you live in a sick society, just about everything you do is wrong.
Yawn, about as exciting as hearing somebody 3d-printed some handgrips. Wake me when they can print a sold steel barrel and bolt at a negligible cost and then maybe people should get, ahem, up in arms about 3d printed guns.
Shit, yo, why we gotta turn everything into weapons, huh? wouldn't we be more civilized without weapons?
Let q be a radix > 1. I am in ur base-q, killing 10 d00ds.
NOT. An individual can legally manufacture a gun. It can never be sold or given to any one else though without having the appropriate permits and paperwork.
This actually could be a good thing. Right now, the public mentality is that gun owner = nut job. Unless Congress is willing to criminalize owning a 3D printer, it might actually force people think about the current state of laws and actually make sensible gun laws.
We don't live in Shouldland.
It's going to get real interesting when somebody uploads a file for a complete printed zip gun. Since people already build them out of pvc pipe, it may be possible to build a usable weapon with extruded ABS plastic.
Toss these 3D printing folks in prison. Then ban guns altogether. There are way too many people defending themselves from spree shooters and psychopaths.
If you ban guns, criminals won't be able to buy them anymore. Remember when they had a war on drugs, and now we don't have drugs anymore??
Not really. I can build a CNC machine for about $600 in parts. I can build a 3d printer for about the same.
Making your own firearms is a well-established hobby in the U.S. Lots of people do it. There are forums devoted to it. Federal law specifically provides for it. It's nothing new. Nor is composite as a material for AR lowers; youtube has plenty of videos of people shooting "Plum Crazy"-based AR rifles. And 3D printing has been around a while.
What's newsworthy here? I don't get it.
IIRC, The Red Jacket .22 zombie gun used a 3D printed body on a metal receiver.

I just saw a TED talk in which the presenter asked this very question.
"and that no gun license is required in most of the U.S. to purchase or possess a semi-automatic weapon."
While true for most people, felony convicts universally aren't allowed to own guns, and even people convicted of misdemeanor domestic abuse. Same for people with drug addictions, I believe.
Note, that applies to OWNING a firearm... nevermind open carry.
Why would the method of construction matter as to what the actual end result is. Even if it's made in the digestive channel of a rhinoceros, if it is able to fire bullets it's a firearm and should be regarded as such by regulations.

Cost. 3d printers can cost a LOT less than a CNC, both for purchase and continued operation.
And skill. Even if you have the CAD files or G-Code, a CNC mill requires a lot of skill to set up and run. With a 3D printer, you just push the "start" button.
My kids use a 3D printer to make toys and doll furniture. But they are not allowed to touch the Sherline CNC mill in the garage unless I am with them. It is dangerous and they don't have the skill to operate it.

Heh. One thing to realize is that the NRA is a bit like the ACLU. It's actually considered 'not extreme enough' and 'too willing to bend' by some, there are more extreme organizations out there like the 'Gun Owners of America'.
But I'll agree, the NRA does have some kooks in it, but mostly they're there because they recognize the NRA as the '800 pound gorilla', so they throw some support to it, while also supporting the 300 pound gorilla who is, theoretically speaking, mauling some of the anti-gun gorillas around the corner, so the big guy gets even more done. /Lifetime member of NRA AND GOA.

What a douchebag.
There is a reason why firearm manufacturers create parts out of single bar stock aluminum or steel metal pieces and machine them out, that is to maintain durability during firing process of the gun so it doesn't explode in your hands and injure you or worse and that it will last over repeated uses.
The most difficult part of creating the gun is the creation of the barrel with a chamber that can withstand pressures of 22,000 to 55,000 pounds-per-inch and not explode into shrapnel hurting you badly. Barrel creation is difficult and taken very seriously with many manufacturers using a magnetic particle inspection process to ensure that there are no metal weak points or fractures inside the walls of the barrels to prevent them from exploding.
Until these low priced home 3D printing machines can print out of aluminum, steel, or other metals to maintain some kind of rigidity on the parts these printed firearm pieces will just be an exercise in computer aided design and prototyping. Many of the pistols now use plastic frames
As far as legality of manufacturing your own firearm by people who are somehow restricted by law from owning one, well it's the possession and ownership that is restricted, not the creation so all possession restrictions still apply.
You can create your own firearms according to the Gun Control Act of 1968 for personal usage just not sale or distribution. If you decide to make these 3D printed firearm receivers you would have to apply for a Federal Firearms License type 7 or 10 and register your business then put serial numbers on these parts.
I honestly don't think I'd trust anything over .22 made from plastic. My Mosin Nagant fires 7.62x54R and that thing packs a WALLOP.

It's always been easy enough to make AK type guns by hand without needing a 3d printer. I own a home-made AK that I built over a weekend with the help of a friend.
The NRA is 4.3 million Americans who care enough about their rights to put their hard-earned money to work (via dues) protecting those rights.
No, money is not the key to the NRA's success. Its success is due to the fact that its members are highly likely to vote.
The true currency of politics is votes. Money is just a tool to attempt to persuade voters.

That is a very close minded and telling statement.
Not really. "Military Grade" is a political fiction, the civilian AR-15 is functionally identical to popular hunting rifles. It's "military" only in a cosmetic sense, black plastic instead of wood, same sights and controls as the M-16/M-4. In operation it functions like many hunting rifles, semi-automatic only (one shot per trigger squeeze), it leaves the factory with a 5 round magazine just like the hunting rifles, it uses the same ammunition, etc. The NRA opposes (in part) an assault rifle ban because they understand the functional definition of a rifle like the AR-15 (detachable magazine, semi-automatic, ...) would apply to many hunting rifles as well.
They think it's an infringement of their 'rights' to even be required to be trained to use the weapons they are buying.
The NRA is the largest firearms safety training organization in the world. They got into the political debate only because well meaning but ill-informed politicians were going down the path to outlaw (sometimes unintentionally) traditional hunting and target shooting firearms.
... not to build guns out of everything? Or is that hardwired at birth when you are an american?
While it's cool to see 3D printers becoming more and more advanced, the "Gun" part of the article feels like hype and buzzwords to help increase clicks.
People have been mass-producing AK-47s in countries that can't keep cars running. They're about as low-tech as possible. Being able to use a high-tech device like a 3D printer to construct one small section of a rifle pales in comparison, when looking at the possible legal ramifications.

How about remove all gun laws except two.

Guns are irrelevant in the case of the Aurora shooter. He possessed enough intelligence to booby-trap his apartment. If guns were illegal, he could have done the same or greater damage with IEDs. If the materials to form IEDs were illegal, he could have done a lot of damage with acid the way the crazies in Afghanistan do.
In other words, you cannot totally prevent this sort of thing by any measure tolerable by a free society. This will always be the case until you tie every citizen's hands behind his back and only allow him to move them under closely monitored cases. Even then, the intelligent ones will find a way.
Let me suggest something controversial--let's correct the gross and systemic inequality, in material terms, of our society. That eliminates an entire swath of economic-based grievances. Let's also address the endemic prejudice of society against intelligent kids in favor of physical kids; this has been salient since Columbine, but no one in America has done anything meaningful against it except to further stigmatize intelligent kids.
I know, this is crazy talk. Let's all double-down on the status quo instead. Let's criminalize everything we possibly can, flying in the face of the constant march of technology. Nevermind that soon everyone will have the ability to manufacture their own guns and worse in defiance of all prohibitions. Nevermind that it will soon be possible for an enterprising, but disgruntled, teen-ager to manufacture his own variant of Ebola. Nevermind that it will soon be possible to enterprising nerds to mastermind the mass-execution of the 1% via swarm-controlled bots.
No, let's continue to plug our fingers in our ears and pretend that the status quo is fine. Remember, I said it here first.
If not us, who? If not now, when?
As an NRA member I'll add that my experience is that nearly all members I've met think that requiring a safety class before buying that first firearm is a good idea. Just like requiring a hunter safety class before getting that first hunting license. Note, a hunter safety class is mostly general firearms safety, not really hunting specific, so the necessary infrastructure already exists.
That said, despite its draconian slippery-slope attitude, the NRA will still get our support as long a there are well meaning but uninformed (in a technical sense with respect to the operation of firearms) politicians who will outlaw legitimate hunting and sporting rifles in so called "assault weapons" bans. "Assault Weapon", "Military Grade Weapon" are political fictions. To avoid redundancy see: http://hardware.slashdot.org/comments.pl?sid=3007097&cid=40780589
There is a great photo of Bill Clinton going duck hunting with a assault weapon (shotgun, not riffle) –IIRC – right after he banned their sale as president (ban has since expired). In this day and age a pistol grip is considered more intuitive. It is a style thing - how you hold your weapon.
What happens if some point in the future people can manufacture Bazookas using 3d printers. Won't the world get a lot more dangerous?
SELF reported poll shows 47% of Americans are willing to tell the government they have guns, Tell me how comfortable are you telling a stranger you own a gun?
ATF NCIS and NRA data shows there are about 9 guns for every 10 Americans, expect that number to be higher due to citizens uncomfortable telling big brother they have guns as well.
First, it is still SIGNIFICANTLY easier to get a real gun versus printing your own gun.
Second, even if it is impossible to buy real guns and everyone resorts to printing their own guns, people will ALWAYS find a way to kill each other. Ban all guns and all ways to make a gun, people are going to sharpen down their toothbrushes to do the trick.
There is a fundamental failing in society that results in people not valuing other people's lives.
The ways people kill each other is moot and yet so much energy is spent debating and complaining about the availability of weapons. The WHYS people kill each other is more important and should be the focal point of effort to correct.
I haven't thought of anything clever to put here, but then again most of you haven't either.

Nothing worse that letting everybody know how this can be done.
It would certainly cut down on the massacres, hunting accidents and domestic fatalities. Is that a bad thing? For us Europeans it doesn't look like it.
A hypocrite is someone who tells people to act one way, and then acts another.
Supporting one position, but not supporting another position (even if similar, related, or compatible), does not make one a hypocrite. Neither does supporting two contradictory positions.
"Contradictory" is not the same as "hypocritical."
"Military Grade" is a political fiction, the civilian AR-15 is functionally identical to popular hunting rifles.
Except he managed to shoot 79 people within the span of a couple minutes. Do you think that is even remotely possible with a regular hunting rifle?
The AR-15 is functionally equivalent to many hunting rifles with detachable magazines and that are semiautomatic in operation. Many hunters have taken such hunting rifles to an appropriate location, dropped out the 5 round hunting magazine and popped in a 20 round target shooting magazine to punch holes in pieces or paper (an Olympic sport by the way), knock over metal plates (some shaped line the animals they will hunt), etc. Such a rifle is virtually identical in capability to the M-14s and original M-16s used in Vietnam, differing only in having no full-auto option. So yes, the same thing could have been done with popular hunting rifles.
More importantly I believe the AR-15 that the nut was using jammed and he switched to a Remington 870 shotgun. The 870 is very popular with hunters and it is also used by the military. Plus a 12 gauge shotgun is deadlier than an M-16 at close range. Note that during the 1st gulf war of the 1990s Marines traded in their M-16s for 12 gauge Mossberg 500 shotguns (also quite popular with hunters) when they planned to enter Iraqi trenches and command bunkers.
The term "Assault Rifle" actually applies only to rifles capable of full-auto operation. When the rifle is semi-automatic only "Military Grade" is a fiction, relying only on cosmetic appearance not actual functionality or capability.
In the USA, this can only be a good thing.
What this enables is the possible production of millions and millions of more guns, which is perfect for fixing the out of control gun culture in the USA.
Remember, the *only* right solution to lots of guns is.....more guns! amiright?
Nobody will ever take away the Americans GOD given right to shoot lots of people to death. Its the only answer to everything.
Cost....And skill.
Indeed. I'm a CNC programmer in a machine shop. Besides the cost of machines and tooling there is significant skill and work needed to set a mill up to make something. With a 3D printer it's "push button receive bacon."
Well, I guess the Second Amendment has to be rewritten: Everybody has the right to print arms.
I was going to print some plastic knuckles on my 3d printer for fun but after looking for some designs, I stumbled onto the government website that brass knuckles or any similar device is a prohibited weapon. It is kind of scary to think If I get a virus on my computer and it prints an illegal object, I would be subject to prosecution under the criminal code. I don't think I will attempt printing a handgun.
And what happens if we remove instances of deaths where the police are involved? It's important to remember that US police forces are heavily armed and frequently use aggressive tactics, whereas UK police are rarely armed. This isn't merely a difference in armament, but also corruption, training, and tactics.
In a world in which natural, common plants are illegal, it doesn't seem unusual that shapes might be as well.
No doubt, I was thinking the same thing.
TBH, printing your own isn't a problem at all. They still won't have any ammunition. I think the fear people have with "he printed a gun, oh noes!" is that people assume that a printed gun somehow implies one that comes with ammunition, which I would argue is harder to acquire than the actual gun itself.
Are you kidding me? Travels along the long bones? Instant concussion death? Sever limbs? Do you have any evidence of this beyond wives tales and urban legend? Blow a hole in the skull and disrupt the brain? You've been watching too many kids movies.
Mercury becomes a vapor under pressure. It carries significant mass, and will probably make a serious change to firing pressures. The load will need to be adjusted. Look at the safe load differences between a 90-ish gr, 115-ish gr and then 147gr 9mm. As the weight increases, muzzle energy goes down. Using the same powder loads behind the heavier bullet makes a significantly higher pressure.
Beyond that change, show me any gelatin test or even animal carcass test showing the significance of mercury in a bullet.
The simple fact of firearms is newton's third law. The shooter will absorb as much energy as the target. For every action, there is an equal and opposite reaction. .22's just don't have the oomph to do all of the things you're talking about. Grow up, read up, whatever it takes. Without serious evidence, your words ring of conjecture and wild exaggeration.
How is "...no gun license is required in most of the U.S. to purchase or possess a semi-automatic weapon" relevant?
Keep the politics out of it and the tech in.
You think that the having of guns causes the massacres? And that taking them away will suddenly stop people from killing each other?
People who want to massacre will either obtain a gun illegally, or will use something other than a gun.
So, getting rid of the guns does not make us safer, it just removes our ability to shoot back when the criminals come.
Your fear robs you of your rationality.
Re:
"Note that the legal fiction of receiver-as-firearm is true in the U.S"
Since not all parts of a firearm should logically be CONTROLLED as a "firearm" (screws, rivets, stocks, barrels) it is necessary to have a workable legal definition of "firearm".
Controlling receivers is logical, as is controlling the SPECIFIC parts of fully automatic weapons which make them "full auto".
"This post is an artistic work of fiction and falsehood. Only a fool would take anything posted here as fact."

Apologies to Poe
You don't need to have plastic strong enough to withstand dozens or hundreds of firings, you need plastic strong enough to withstand one firing.
I can imagine 3D printing a shape with multiple one-shot barrels, adding some propellant, electrical detonator and a projectile to each barrel, then mounting the assembly on some kind of (probably 3D printed) grip. When all the barrels have been discharged, throw them away and mount another on the grip.
which I would argue is harder to acquire than the actual gun itself.
Going to Walmart is harder than printing something with a 3D printer, mail ordering an upper receiver for it, and then putting it all together?
You're an idiot.
yeah so the Aurora incident would have been solved with a lot less hassle, death and injury with dozens of scared, disorientated people indiscriminately firing at an unknown target in the darkness

As far as firearms go, anything you can legally possess you can also legally build. This is no exception. Besides, how many violent criminals do you think have their own 3d printers? The effort involved in acquiring the knowledge and ability to print a receiver is more than most would be willing to put in when it's easier and cheaper to steal a gun or buy a stolen gun.

3D printing is just a new and interesting way to make parts for a gun. It doesn't magically give anyone the ability to do illegal things that they couldn't have done before.
What is illegal is making certain parts out of a material that has a low melting temperature. This would allow the gun to be easily destroyed after a crime was committed. I don't remember the details, so do your legal research before you start printing.

The NRA is actually an extremist organisation that does NOT represent its membership. Look up their actual positions. Most gun owners/advocates favour responsible gun ownership whereas the NRA advocates a dangerous free-for-all approach that encourages more violent weapons and makes responsible use (like hunting) less practical. Gun owners need to start an new organisation that is not bought and sold big brother corporation owned.
Stupidity is its own reward.
There is a lot of rose tinted glasses and not seeing the sheep for the wolf clothing with the NRA. The NRA is very extreme and surveys of NRA members always result in much more moderate and responsible ideas of gun use than the NRA actually advocates. Just because YOU don't support shooting people/stand-your-ground etc doesn't mean the NRA backs you. Most members have a very distant idea of the policies the NRA puts into law and if they knew it better they would quit their membership!
