Title: First 3-D-printed gun fired, but its digital blueprints make bigger bang
Post by: jimmy olsen on May 06, 2013, 07:39:57 PM
Can't wait to see how 3D printing revolutionizes industry on a broad economic level. The firearm industry, not so much.

First 3-D-printed gun fired, but its digital blueprints make bigger bang

With a shot heard round the Internet, the first known 3-D printed gun is a reality. But the bigger ruckus comes from the gun's digital blueprints, now available for free download by any shooters who want to build their own.

Cody Wilson, the polemic face of the not-for-profit 3-D gunsmith Defense Distributed, fired the organization's latest prototype at the opening of a 28-second video posted on YouTube Friday. "The Liberator," as the weapon is provocatively titled, is a 16-piece firearm made almost entirely of ABS plastic, with a metal firing pin and an embedded metal shank meant to provide enough metal mass to comply with the 1988 U.S. Undetectable Firearms Act.

Blue and white, and bearing more than a passing resemblance to a Star Trek phaser, the .380-caliber pistol fires with a single "pop" in Wilson's hands. Apparently, the design works, though this version was rendered unusable after firing six rounds.

Eight months into its mission to create and distribute the computer-assisted design (CAD) for a 100-percent 3-D printed gun, Defense Distributed is about as close to this goal as it can legally get. That is, provided laws don't change to make what the group is doing illegal.

Even now, Defense Distributed's latest success — though it may be a rather costly and cumbersome way to obtain a firearm, especially one that tends to self destruct — has gun-control advocates on the move. This was predicted by Wilson, who has long said that his group's ultimate goal is not to build arms, but to test constitutional rights.

"I think this isn't a project about firearms, it's a project about political equality," Wilson recently told NBC's Nightly News.

Wilson, a law student at the University of Texas in Austin, is federally licensed to manufacture and sell guns and gun parts, as long as they're not fully automatic. Not only is it legal for Wilson to make "The Liberator," but distributing its plans for others to make it is also legal, according to the Bureau of Alcohol, Tobacco and Firearms.

"An individual who wishes to manufacturer a firearm for his or her personal use does not need a license, as long as it isn't for an automatic firearm," an ATF spokesperson told NBC News.

But the fact that the gun can be homemade and is largely plastic — and therefore harder to spot via metal detectors — has made it the center of a new debate in Washington.

On Sunday, Sen. Chuck Schumer, D-N.Y., endorsed a bill, entitled the Undetectable Firearms Modernization Act, that would bring the 1988 law up to date by banning 3-D-printed guns that "have no metal and could therefore slip through a metal detector." Under the law, it would be a crime to build such a weapon.

"We're facing a situation where anyone — a felon, a terrorist — can open a gun factory in their garage, and the weapons they make will be undetectable," Schumer said at a conference. "It's stomach churning." Schumer said his bill would not restrict the use of 3-D printers for other purposes.

Schumer was speaking in support of legislation, proposed in the House of Representatives Friday by Rep. Steve Israel, D-N.Y., that bans "homemade, 3-D printed, plastic high-capacity magazines."

"When I started talking about the issue of plastic firearms months ago, I was told the idea of a plastic gun is science fiction. Now that this technology appears to be upon us, we need to act now to extend the ban on plastic firearms," read Israel's statement.

On a technical level, enforcing the ban could be challenging. Firmware locks for 3-D printers and takedown protocols for CAD files for firearms have been proposed by some, and scoffed at by others.

"Every one of those measures is a nonsense and worse: unworkable combinations of authoritarianism, censorship and wishful thinking," author Cory Doctorow wrote in criticism of Israel's initial proposal. "Importantly, none of these would prevent people from manufacturing plastic guns. And all of these measures would grossly interfere with the lawful operation of 3-D printers."

It's legal for most Americans to buy guns, and it's also easy for many people to acquire guns illegally, too. Industrial-level 3-D printers currently capable of producing "The Liberator" can cost upwards of $10,000, and require some training to operate. They may never put guns into the hands of people who otherwise wouldn't be able to obtain them, but they still may become tools for nefarious acts.

"This technology is emerging so quickly that few law enforcement officials know what a 3-D printer is or understand how it can be used," Jim Bueermann, former Redlands, Calif., police chief who is now president of the non-profit Police Foundation, told NBC News.

"I think we are going to see some very creative, technologically astute examples of criminal acts that are enabled by this technology," he added. "This is one of the unintended consequences of the democratizing of the Internet."

The thing about this sotry that I find interesting is that it illuminates this rather bizarre attitude of gun nuts: That guns, by their very nature, hold some kind of special status such that they have a value in and of themselves that is special and unique - almost religious. I take that back - there is nothing "almost" about it - it is taken as a matter of faith that guns are some kind of mystical object to be valued in and of themselves.

What is the utility in creating a plastic gun just because you can? On the one hand - so what? It is inevitable that someone would do it given the technology. On the other hand, congratulations - you get to be the douchebag who actually did it and is now so very proud of himself?

Why not be the first to make a 3D dildo or a 3D garden hoe? There is nothing magical about a gun - being able to make one in a 3D printer does not make you special. It just means you get to be the first person to publish something that we will all regret as one of the unfortunate consequences of the rise in sophisticated production processes that makes what used to be difficult easy.

Hell, one of these days some other set of assholes will be the first to create a homemade nuke. I am sure they will think themselves exceedingly clever as well.

This is almost a non-story, other than the amusing aspect of it making certain people shit their pants. These all-plastic guns would probably be more dangerous to the guy firing them than to anyone downrange.

With a cheap drill press you can buy an 80% complete AR-15 receiver and manufacture your own firearm, completing it with parts ordered through the mail. All legal and without serial numbers. Surprised that's not making the news these days.

That has made the news in the past - at least to the extent that I was aware it was possible (although I don't recall where I learned that).

I think this is more problematic from the plastic part of it than anything else. Like the article pointed out, it's not like this is actually useful from a practical standpoint - if you want a cheap, disposable gun, buying a $10,000 3D printer is probably not the best way to go about getting one.

One, no.  It's a hell of a cheap investment into brokering untraceable firearms, though.

This is problematic, though- the trouble is that there's no meaningful way to recreate the technological barrier to 3D printing weaponry.  This is going to have to be tackled from the information side, which is going to raise all kinds of free speech arguments when these blueprints are censored for public safety reasons.

Censorship sounds like a terrible idea. What would be the precedent, when blueprints, recipes, and instructions are and have been legal for all sorts of dangerous illegal devices.

I'm wondering to what extent this is going to throw the airport security checks people out of the loop. Considering that one failed "shoe bomber" attempt made them force us to take our shoes off, I predict the answer is "to a huge extent".

Does it have to be? Could one make a hard plastic bullet in a plastic tube filled with propellent?

Because a plastic case, chamber, and barrel are not going to be able to handle the pressure of a full load.  It would probably just explode in your hand.

Does it have to be? Could one make a hard plastic bullet in a plastic tube filled with propellent?

If one is going through all the trouble of making a plastic gun, why not make plastic ammo to go with it?

I'm sure you could.  But I'd imagine you'd have to use so little powder that the round might not be lethal-- especially with a plastic projectile.

Not sure I understand. Why would you have to use only a small amount of powder (or whatever it is they put in cartridges these days?)

Because a plastic case, chamber, and barrel are not going to be able to handle the pressure of a full load.  It would probably just explode in your hand.

Would that not be a problem with using conventional ammo in a plastic gun? It's the barrel that takes the pressure, not the cartridge; the explosion simply fits the walls of the cartridge more snugly to the inside of the chamber. 

Early "integrated cartridges" were made out of ... paper.

They worked okay, though for various reasons, metal was better.

The Diamond Age (http://en.wikipedia.org/wiki/Diamond_Age)

QuoteMatter compilers receive their raw materials from the Feed, a system analogous to the electrical grid of modern society. The Feed carries streams of both energy and basic molecules, which are rapidly assembled into usable goods by matter compilers. The Source, where the Feed's stream of matter originates, is controlled by the Victorian phyle (though smaller, independent Feeds are possible). The hierarchic nature of the Feed and an alternative, anarchic developing technology, known as the Seed, mirror the cultural conflict between East and West that is depicted in the book. This conflict has an economic element as well, with the Feed representing a centrally-controlled distribution mechanism, while the Seed represents a more flexible, open-ended, decentralised method of creation and organization.

Implicit in the Feed technology were limitations on what could be created.

They worked okay because the chamber and barrel were metal.  Not to say that you couldn't do something similar in a plastic gun, but like I keep saying, you're not gonna go full power.  I kinda doubt the lethality of a plastic gun.  With range, accuracy, and caliber being so limited you might as well just walk up & stab someone with something.

The issue, though, at least my issue, was why it would not be possible to have non-metalic ammo.

No doubt an all-plastic gun will not have the same lethality as an all-metal gun, or have bullets that travel as far - but it doesn't have to. The only reason to have an all-plastic gun in the first place is to avoid detection. All it has to do is to be able to intimidate or kill people, presumably at short range, like a hostage-taker sticking the thing in a person's face.

I don't see why a very hard plastic bullet would not be deadly, albeit not as deadly as a metal one. Again, it doesn't have to be.

It would probably not be as "good". Lead is perfect for bullets made to kill people, being both very heavy and with the ability to deform when it hits flesh and bone.

That noted, a hard plastic bullet doesn't have to be as "good" as a lead one - it could still kill people just fine.

I think paper rounds were used in muzzle loaders. The powder in the paper gave the right power charge needed. It was poured into the barrel, not loaded like a bullet.  A paper casing would foul a gun as it would leave debris in the chamber and barrel.

By contrast, a rifle round apparently blew it up:

QuoteThe printed gun seems limited, for now, to certain calibers of ammunition. After the handgun round, Wilson switched out the Liberator's barrel for a higher-charge 5.7×28 rifle cartridge. He and John retreated to a safe distance, and John pulled his yellow string again. This time the gun exploded, sending shards of white ABS plastic flying into the weeds and bringing the Liberator's first field trial to an abrupt end.

QuoteWilson showed me a video of an ABS plastic barrel the group printed attached to a non-printed gun body firing ten rounds of .380 ammunition before breaking on the eleventh.

Interesting, so there were paper cartridges used in some breech loading guns, and apparently pretty effective. Thanks for that link Raz.  I had never heard of that before. And the paper burned entirely when the gun was fired. Should be useable in a plastic gun, though still the plastic barrel may not be able to handle a heavy load for extended time, but something like a .22 caliber may work.

If plastic doesn't work well (and in spite of your repeated statements I don't really see why not - many plastics are extremely hard),

Plastic bullets are specifically used as non-lethal rounds for crowd control* (and training in some cases).  If some new, dense, space-age plastic would make a good lethal bullet projectile there would probably be something like that on the market.  Ammo manufacturers love gimmicks.  About the closest I see to that in the "lethal" category is a polymer tip that just helps the copper-jacketed lead round expand.

*Before some goofball tries to use it as a gotcha, yes there have been isolated instances of people dying from plastic or rubber bullet wounds, but I'm talking about relative lethality.

Quotewhy not stone bullets in a smoothbore?

:huh: Those are plastic bullets especially made to be non-lethal as a design feature.

Not all plastic is the same. Some is very hard and some is softer. That's why manufacturers like plastic, it can have different consistencies, depending on the formula.

Just because non-lethal bullets = plastic, it does not of necessity follow that plastic bullets = non-lethal.

I doubt though that you could make a plastic with all the desireable qualities of lead, like heaviness. Lead bullets will probably always be somewhat better for killing than plastic ones ... but a terrorist or robber would no doubt be happy to exchange the more desireable lead for plastic, if they wanted to hijack an airplane or something.

QuoteAccuracy, maybe?

I imagine it would be as accurate as a shotgun firing slugs.

Good enough for a bank robber or a terrorist, anyway.  ;)

But 3-D printers are progressing.  The types of plastic they use are improving.  Remember there are already firearms out there that are mostly plastic.

It's not impossible to imagine that in 5-10 years someone would be able to reproduce a fully functional AR-15 in a 3D printer, either out of advanced polymers, or out of metal (they're working on that as well).

I'm not saying it couldn't kill, just that it wouldn't be nearly as lethal as a metal bullet.  And that it may not be lethal enough to use over other alternatives.

I'm sure it can contain *a* blast-- just with less powder than what you'd use in a normal gun.  Even with that I wouldn't dare fire it.  And like I said, a plastic bullet isn't going to be a particularly deadly projectile.

:huh: A high density plastic bullet is more than capable enough of killing someone.

And while nobody sane would dare fire it, that's not the ones that we worry about. A perturbed person would be perfectly willing to do so. Or someone toying with suicide. Or even just a kid. That's an interesting angle actually, how are you going to keep children and teens from downloading and printing weapons?

And then there's another angle: what about those countries where guns are rare?


I have a very hostile attitude against censorship but this tech creates quite a dilemma.

I have full faith that our American friends will be as successful at keeping plastic guns out of the hands of kids, deranged maniacs or criminals as they are when it comes to ordinary guns. :)

You know, there is an interesting analogy here - porn.

Today, how do you police and manage access to pornography by your kids?

When I was a kid, of course we were not allowed to have porn, and my parents would certainly punish us if they ever found any (not that it stopped us, but there was risk involved, etc., etc.)

Today, I feel kind of silly telling my son he is not allowed to look at porn - he isn't, but we cannot really control it *at all* via any kind of attempt to control their access to it. It is too easy to get if they want to get at it, with the internet just a click away.

So we don't even bother trying to control it's impacy by simply trying to control the physical object of pornography any more. Rather you have to try to

1) Teach them some self control and appropriate/responsible behavior, and more importantly
2) Teach what porn actually means, what it doesn't mean, and how to keep it from negatively shaping their views towards sex and sexuality.

You simply cannot, in any meaningful way, hope to deal with the issue via restricting exposure anymore, so you are forced to deal with the consequences of the exposure instead.

If guns become so easy to make, then bitching about it won't change anything - rather it will simply become more imperative that as a society we deal with what that means, the dangers they present, and how to handle them.

If nothing else, maybe it would cause the gun nuts to stop masturbating all the time over their penis symbols?

But we do in fact have a variety of restrictions on possessing certain types of porn.  Child porn.

Despite the fact it is ridiculously easy to find, possess and distribute child porn if you are so inclined, we make it a criminal offence to do so.

You are talking like these are BBs.  They aren't.  A high grade plastic bullet would likely go through a person as well as as a steel one.  I mean, they have a pretty good tensile strength.  They don't deform as well, but would still cut through someone.  Or if you don't like plastic, why not ceramics?

No it wouldn't.  There is no plastic that will penetrate as well as steel. Also, keep in mind we're talking severely limited velocities here, at least with this dude's current design/materials.  He's using a .380 round which isn't the best self-defense round to begin with.  Replace the projectile with a "high grade" plastic one, and you're going to get even less lethality (bound to be lighter, meaning less kinetic energy) than the lead/copper bullet. 

And that's not to even mention the lack of accuracy, coming out of a short plastic smoothbore barrel.  You'd probably need to be within a couple yards to even score a hit, and if you're that close anyway you might as well use a knife or something that you can attack with repeatedly.

Maybe someday there will be a proof of concept for an all-plastic weapon that can rapidly fire multiple accurate shots with predictable lethality, but we're not there yet.

But if you guys want to panic, go ahead.

You are unnecessarily cincerned about the performance of this weapon.

Think of it this way: who, exactly, would want an all-plastic gun, and for what purpose?

They aren't likely to want it for Olympic target shooting. More like to shove in someone's face after sneaking it through a metal detector. Accuracy and other performance characteristics are strictly secondary, as long as it could actually, you know, kill someone.

IIRC it was made from whatever the current material is was only strong enough to shoot a few .22 rounds and then it broke.  A high quality polymer would be a lot stronger, though probably not as strong as the ones that are simply molded.

No doubt an all-plastic gun will not have the same lethality as an all-metal gun, or have bullets that travel as far - but it doesn't have to. The only reason to have an all-plastic gun in the first place is to avoid detection. All it has to do is to be able to intimidate or kill people, presumably at short range, like a hostage-taker sticking the thing in a person's face.

It can have the same lethality;  and so what if it breaks after the 1st shot.  That may be all that is needed.

The article claims not:  "[t]he Liberator fired a standard .380 handgun round without visible damage."
http://www.forbes.com/sites/andygreenberg/2013/05/05/meet-the-liberator-test-firing-the-worlds-first-fully-3d-printed-gun/

By contrast, a rifle round apparently blew it up:

QuoteThe printed gun seems limited, for now, to certain calibers of ammunition. After the handgun round, Wilson switched out the Liberator's barrel for a higher-charge 5.7×28 rifle cartridge. He and John retreated to a safe distance, and John pulled his yellow string again. This time the gun exploded, sending shards of white ABS plastic flying into the weeds and bringing the Liberator's first field trial to an abrupt end.

QuoteWilson showed me a video of an ABS plastic barrel the group printed attached to a non-printed gun body firing ten rounds of .380 ammunition before breaking on the eleventh.

A .380 cartridge is loaded to an av pressure of 21,500 psi

A FN 5.7x28 is loaded to 50k psi
Well da it's going to blow it up. :rolleyes:

You are talking like these are BBs.  They aren't.  A high grade plastic bullet would likely go through a person as well as as a steel one.

No it wouldn't.  There is no plastic that will penetrate as well as steel. Also, keep in mind we're talking severely limited velocities here, at least with this dude's current design/materials.  He's using a .380 round which isn't the best self-defense round to begin with.  Replace the projectile with a "high grade" plastic one, and you're going to get even less lethality (bound to be lighter, meaning less kinetic energy) than the lead/copper bullet. 

And that's not to even mention the lack of accuracy, coming out of a short plastic smoothbore barrel.  You'd probably need to be within a couple yards to even score a hit, and if you're that close anyway you might as well use a knife or something that you can attack with repeatedly.

Maybe someday there will be a proof of concept for an all-plastic weapon that can rapidly fire multiple accurate shots with predictable lethality, but we're not there yet.

But if you guys want to panic, go ahead.

QuoteI mean, they have a pretty good tensile strength.  They don't deform as well, but would still cut through someone.  Or if you don't like plastic, why not ceramics?

I think ceramic would be more effective than plastic.  You still have the accuracy and single shot issues to deal with.

You only need one shot to kill a person.  What was the type of bullet that used in the Reagan assassination attempt?  It crippled one man, and almost killed the President.  Was it a more powerful or less powerful round then a .38?

Than a .380.  .380 ACP is a lot punier than .38 Special (which itself is considered relatively weak compared to other calibers)

Anyway, the weapon used in the Reagan assassination attempt was a .22 revolver.  And with conventional ammo, .22 is weaker than .380.  But Hinckley used these weird bullets that were designed to explode on impact, so that muddies the waters a little bit.  Only one round actually did explode-- the one that hit Brady.  All six shots actually missed Reagan, though the last one freakishly ricocheted and then hit him in the side after he was in the limo.

Well a Derringer cannot do any of those things either but it was perfectly sufficient for assassinating the President of the United States.

Besides until we have 3-D printers as common household accessories this is not a serious point of concerned and that gives whomever is working on this project plenty of time to improve their plastic gun design.

Okay, if I shot a person with a .380 at point blank range what would it likely do that person?  Say I shot them in the Chest or head.  Would they be wounded?  Would they laugh it off.  Would they die without medical attention?

Depends on a lot of variables, but yet it could kill them.  But if you're stuck with a single shot .380 pistol and have the ability to get that close there are (non-firearm) weapons that would probably be more effective.  Getting kinda tired of having to repeat that.

This line of argument just isn't convincing.

There is a reason why people have been making small, easily concealed firearms since there have BEEN firearms, despite the fact that such weapons are pretty well by definition fairly low-powered and inaccurate - and that reason is that it is a lot easier to kill someone with even a tiny gun, then to hack them to death with an equally-concealable knife.

No-one thinks that a plastic pistol is going to replace an assault rifle in deadliness any time soon; its natural forebearers are things like derringers - guns made specifically to be inconspicuous and so concealable. Only in this case, it is concealable because of what it is made of, rather than because of its size. It's the natural tool of the assassin, the terrorist and the criminal.

I wasn't thinking of a percent chance.  Just sort of "very likely", or "not likely at all".  Knife wounds tend to be much less damaging then gunshot wounds, if for not other reason then you have to be fairly skilled with a knife to kill with only one stab.  Knife attacks tend have multiple wounds and have a much higher rate of recovery.  Doing a little bit of research, William McKinley was killed by a .32 S&W bullet which is a smaller bullet with less power then a .380.  So it would be my understanding that a while not as effective as say a shotgun, a flamethower, or .50 caliber bullet a .380 is quite deadly and being shot with one would be a very serious and life threatening event.  Do you disagree with this?

You said kept mentioning that other weapons are more effective, which is a strangely evasive way to dismiss the bullet's killing power.  Since you never mentioned what other weapons were so I had to extrapolate.  I don't think it's hyperbole to say that a flame thower is more damaging then a .380 pistol.  I'm not petulant, in fact I'm quite amused by you attempts play down the killing power of a certain round.

It's not undetectable.  The weapon that has been demonstrated has a metal nail for a firing pin and a metallic .380 round.  Untraceable doesn't concern me so much, as it's already legal to manufacture untraceable weapons.  I will grant that it's potentially lethal.  But I'm not losing much sleep over it yet.

Just out of curiosity, have you ever taken an airsoft round from a gas gun?  That's enough to wound, and that's just a little hollow plastic sphere.  If we loaded a hard plastic equivalent of a slug, it might not have the stopping power of metal ammo, but for its intended purpose, it'd only need to work once.

Without the ammo, it'd be difficult to recognize just a firing pin for what it is.  It'd make metal detectors a hellacious experience, since one tiny metal shank could lead to a full search, when it could just as easily be a piece of a pen that's fallen out, even a metal bobby pin.

Actually it sounds like a well thought out and effective attack.  There seems to be a little gun snobbery here.  Sure a dense plastic bullet or ceramic bullet may not be as effective as conventional one, but I strongly suspect it would penetrate tissue.  If someone were to smuggle one into a campaign rally and got up to the line where they shake the President's hand they could easily kill or at least seriously wound the President.

A lot of this is also mental masturbation.  We know what round was put in there, but what we don't know is the muzzle energy of this gun.

You guys keep talking about the worst possible scenario.  Yes, lots of things *could* be lethal.  But shooting a plastic slug at someone doesn't seem like a well-thought out assassination attempt.
Is that where we're setting the bar?

Nor accuracy.  A smoothbore plastic barrel isn't going to be too accurate (nor will it help in the muzzle energy department).

On that I agree.  There's really nothing that can be done to put the lid back on. 

Didn't you just spend pages saying this is nothing to lose sleep over and not a big deal?  Now it is suddenly Pandora's Box being opened? :hmm:

We'll see.  My main concern here is things like this will essentially invite more and more government powers and control in their attempts to do their basic job: protect people and property.

Well if you are smuggling a plastic gun around the idea is to get it inside of a secured area.  In that case you will probably be firing at point blank range since they will not be expecting you to have a weapon.  I also think the idea a knife would be more effective is rather absurd, it takes a bit more skill and physical strength to take somebody down with a blade than it does to point a gun and pull the trigger.

Muzzle energy of the gun??? Depends on what cartridge the "gun" is shooting  :huh:

Velocity of Bullet
Weight of bullet.

Was said it was a .380 right? Standard factory loaded round right?  With a 90-95gr bullet at about 950-1000 fps thats in the neighborhoood of 190-200 foot pounds at the muzzle.

It's just going to be the zip gun of the 21st century.  Doesn't need range or firepower or any of the other characteristics that gets derspiess to roll over and annoy the wife when it's not even his birthday.

I dunno about that.  I always heard the refrain "run from a knife, close on a gun" in training.  A knife'll kill you quicker than dogshit, and it doesn't need to be expertly wielded, either.   You can bleed out before you even realize you were stuck.

That a fact?  Their lethality is pretty evident in stats (they are always a strong second behind handguns) but as somebody who has never killed anybody I know what I would rather have, even at close range.

That's from a 3" barrel. Smooth or rifled is really irrelevant at PB range. Besides, all things being equal, a smoothbore would be faster in terms of velocity. Less accurate, however.

I'm not quite sure what's being debated here.

Blades can absolutely be dangerous.  And totally agree you might not even feel it.  One of my favourite war stories was the guy who was having a birthday party, and wound up inviting a bunch of people he didn't know over to his house after the bar closed.  One of these guys was playing with his replica samurai sword.  So homeowner takes the sword and gently pokes the guy with the tip saying "don't touch my stuff".  No one thought anything of it at the time until 5 minutes later when the guy collapsed - his heart had been nicked.

Agree with the "run from a knife, but close to a gun", but I'd still rather deal with a knife weilding maniac than a gun weilding one, since I'd put more trust in my ability to run away than my ability to wrestle the gun out of the guys hand.

The barrels don't look even 3" to me (assuming the chamber is integrated into the barrel).  And you're assuming there is a tight fit between the bullet and smoothbore barrel-- I would wager that there is some space there to prevent excessive pressure.  Finally, with the the barrel being plastic there's bound to be some "give" or slight expansion that you wouldn't have with a hardened steel barrel.  That's going to let some gases leak out.

Fucker should have been considerate enough to at least put it through a chrony so we'd see the velocity to confirm :angry:

Me either, given that ABS' tensile strength is only in the ballpark of 4,300 psi.

Basically, knowing the tensile strength of ABS, what likely happened was that the chamber and barrel were cracked by the first shot and exacerbated by the subsequent shots until failure.  Still, knowing that cartridges can be loaded for rimfire pressures up to 40,000 psi, I wouldn't want to take the chance that the gun won't blow up- especially given the 3d printing process is granular in nature, so even designing this as a throwaway weapon is problematic, since you can't necessarily plot where the stress points in the chamber and barrel are and how they'll deform.
