3D-Printed Semi-Automatic Gun Is Simply Terrifying

When I decide to exercise my brain I play Sudoku. When Youtube user Derwood exercises his brain he creates a semi-automatic gun that 95-percent 3D printed, completely untraceable, and currently very legal.

“No one had ever tried to get a semi-automatic 3D printed gun working before…I’m just one of those types, I like to find new things that people say can’t be done,” he told Wired in an interview published earlier today.

Most people challenging engineering preconceptions in their garage just, like, make their car go faster. They don’t craft a killing machine small enough to fit in a purse.

Derwood’s engineering feat, the Shuty-MP1 isn’t 100 percent 3D-printed. Completely 3D-printed guns usually have a habit of failing—often dangerously. You see, the heat from firing melts the PLA plastic used by the majority of 3D printers. In turn, the heat from the repeat usage necessary for something like cracking off eight shots in under 10 seconds is unsustainable for the weapon. To circumvent this issue Derwood used store bought components for some of the biggest points of failure: the barrel, hammer, firing pin, bolts, and springs.

None of those components are regulated by current law as you usually need a gun to make use of them. The rest of Derwood’s weapon exists in a gray area. While 3D-printing a weapon isn’t illegal, the release of the CAD plans for it is. As long as Derwood keeps his build instructions off the internet he’s safe. According to Wired he has no plans to release them. Let’s hope not.

Even if his plans did leak he doesn’t think untraceable semiautomatic weapons will be flooding the streets and flowing into the hands of criminals. “If you keep shooting, it’s going to fail,” he hold Wired. “That makes it not such a desired weapon for a criminal.”

So all you have to do is dodge bullets until the gun fails. Phew.

Yes, but. Right now, in use for things that generally don't include gun building, are 3D plasma printers that print in melted metal. Once they become more refined, and the price comes down, people will buy them for home use, and make their own computer programs for printing metal guns.

However, there is a tabletop milling machine that sells for $1200 to $1500, that makes lower receivers for all kinds of guns. These lower receivers have no serial number.  See https://ghostgunner.net/ and http://www.computerworld.com/article/2689843/3d-vendor-sells-1500-part-to-make-metal-guns.html.

Yes, it's not illegal but soon, someone will find a way to ban it. And it's very convenient that while the gun itself is not illegal, posting the CAD plans is. They always have a loophole.

You know you can buy a 80% complete receiver from California.

Its not considered a firearm if its 80% or less complete.  They come with complete instructions and sometimes tools.  You buy it finish it.  With as much as a regular hand drill and build your AR-15.

In most states it is fully legal to posses the firearm after it is built.  It is just illegal to resell it.  The gun will be your for life.

3D printed guns are a real thing.  I had a friend that printed a .22LR pistol.  Yes I fired it.  Works just like the real thing.  Still saving for a 3D printer.  Want to print an entire arsenal.   lol

feds keep trying to put stricter gun control laws in effect.  With tech like this it will not work.  If people cant buy they will make.

Think of a home made shot gun.

Simply a piece of pipe and a trigger mech and that it all you need.  Not to mention it safer then you think.

Or another thing.  Black Powder pistols.  They are legal to buy by about anyone.  You can buy one with a CC or prepaid and have it shiped right to your door.  Then purchase a replacement cylinder that can fire anything from a .22 to a 45 colt round.  Drop in place and there ya go a fully funtional firearm that no one knows you have.

There is always a way to get a firearm.  Criminal or not.

Like I have said before.

Fed will not win the war on Drugs, Guns, or anything like that.  Just not possible.  Wasting there cash on the war.

Well, a war won is a war lost. As in lost employment and profits. So they go on and on. All those wars are a very convenient way of hiding unemployment as most production disappears and of course there are always business opportunities and profits attached.

3D printing guns was so 2013:

Granted, not everyone has $1M for a 3D-metal printer...

The only part you would need to print is the part with the serial number on it, usually the lower receiver... every other piece can be easily bought online legally (definitely do not print a plastic barrel)

For those folks who oppose gun control stridently, this is not terrifying at all. Its power in the people's hands.

After this reading article, I'm sure that some countries will ban using 3D printers claiming that they want to prevent people from creating guns !!

Is a printed gun reliable and safe to use? Plastic guns are BS, and even made with metal I would be wary of some home-made printed gun. You need high quality steel to make a gun, and precise manufacturing. Sorry for 3D fans, but I'd rather get a gun from an established manufacturer.

You are right. However, it is the people who print guns who are thinking about their own safety. This is why they do tests with their creations, to find out about safety.

The questions revolve around how you are going to test the guns you might print. Once you have printed and tested many, you will know what works and what doesn't, first hand. You won't have to trust some salesman who tells you that printed guns are safe.

Countless cats are out of countless bags. With the advent of stuff like this and ever more p2p options governments are going to be left in the dust. I wonder whether they'll reach a point where so many resources are tied up whacking moles that they'll consider some nuclear options when it comes to the internet.

This is not terrifying.

It is only an early stage in the adaptation of weapon technology to 3d printing.

3d printing requires re examination of basic concepts such as "what is a cartridge?"  "what is a barrel?"  "What is a firing mechanism?"

Bullets, for example, may be made with short integral barrels.  All barrels may be one use throwaway.  Etc.

The duplication of an existing firearm on a 3d printer is a waste of time.

Well said.  Very true wouldn't cost much to make a barrel every time depending on what use you were using the gun for.  1 shot barrels would be great for certain situations while say target practicing it would get pretty expensive and not much fun after the few shots.

As for safety that would depend on what you are trying to accomplish.

I would think that all rifle rounds would be out of the question.  as the high pressures  that they excert when fired.   But for smaller general round this could be easily accomplished.  I would fire a .22 threw a plastic barrel (maybe)   lol.  As for say a 50cal that would be obvious that it wouldn't work.  You would need a barrel with much greater strength.

If you are constructing a handgun styled gun.  you could essentially drill your own as long as you had a way to drill it.

But until printers are cheaper ill still to my BP guns with a replaced cylinder.  they come in all different sizes.  .22 9mm 40 45 45colt and just about everything in between.

Imagine a world in which powerful firearms can literally be downloaded and printed into real life with only very small costs. We live in this world today. It gets a little complicated because firearms is illegal or at lease heavily regulated in most advanced states. I'd imagine countries regulating 3d printing in the future if such weapons end up being used in terror attacks.

Think of the possibilities.

Terrorists would prolly use this for printing hand grenades and other such things.

That could get interesting.   But I want nothing to do with that I would be in it for the firearms only.  I love going to the range.  Great way to spend a weekend.

I am sure most of you have listened to someone say this before.

But Guns don't Kill People, People kill people.  Why punish the ones who use them for sport or a weekends fun.

Even if they are semi auto or even full auto.

Its really not hard to make most guns full auto.  Hell you can buy kits online for just about any assault styled rifle.

Funny thing is.  It really can not be regulated.  Simply because of the fact that they can not regulate parts.  Only firearms themselves.  Hench the reason most states (almost all) do not consider a BP pistol a firearm.  Its considered a part in most states.  Weird huh?  Plus it doesnt take a cartridge.    Buying a replica really isnt a replica now is it.   Its a part that works with more effort then just dropping in a cartridge.

I love this subject.   

it should be illegal because it is very dangerous to make custom made guns.. i'm afraid of future..

I'm not so familiar with 3d printing, and actually I never used anything like that, but i know that 3d printing is future and lot of good things can be printed that way..now i don't know at least for now is that way made gun safe and effective for use? if you can by gun free in shop that you can print it free also but what is here important is the question is this gun safe?

I wouldn't touch a BP gun with a "replaced cylinder" without doing some engineering analysis on the metals and the powder.  Although as you not a 22 is trivial.  Generally, though, the BP guns are rather interesting.  BP is quite dangerous but the modern replacements are safer. 

Until you've loaded up a black powder gun like a 1847 Colt Walker, tamped the charge down, squeezed the balls in, covered them with wax, set the primers, and pointed that thing downrange, you simply can't appreciate what those guys in the 19th century went through to keep their families safe and put food on the table.

As for 3d printers, they are here now and their abilities are here now...

I actually have several BP guns.  All steel frames.   You do not want to put the replaced cylinders in a brass framed BP revolver.  Repeated pressures can damage the frame.  The others that are an all steel frame are completely safe.  I have shot thousands of rounds threw them.

I do like to pack my own rounds in from time to time.  44 cal round balls. 

BP is pretty safe.  As long as you know what it is.  Main difference in powders is flash rate.

BP when reloaded in a cartridge has to be packed.  While the newer powders can sit lose.  You can pack 20 grains compared to say like 3 grains for the same boom factor.  give or take.  Newer powder is more stable but  can have a bigger boom is contained and ignited compared to BP.  I myself make my own black powder.  Its fun and works well.  i like to reload my 45 colt rounds with conicals for the BP revolvers.

Biggest thing about BP guns are to keep them clean.  BP gets pretty dirty pretty fast compared to newer smokeless powders.

its a fun hobby and yet they can still be used for hunting and target practicing.  And is way cheaper then buying ammo all the time just for tagret practicing.

I, personally, have seen a lot of youtube videos on how to make an AK-47 from scratch. You only need a basic metal shop. And from what I've understood there is only one part that is considered to actually be the weapon from a legal standpoint. The rest you can simply order from the internet.

Are you referring to actual black powder or the synthetics, Permadex (??? not sure I recall the names.)  Most likely it would be true that practically anything steel would withstand the black powders.

Gunsmith here locally has a whole display of guns that blew up on reloads, some killing their owners.  I think all the reloads were modern powder, though.  I'm a believer in "reloading to save money" but no way a believer in "reloading for more power."

It was in 1909 when Henry Ford, master of efficiency and standardization, famously said that a “customer can have a car painted any color…so long as it is black.” While the First Industrial Revolution introduced machines to replace hand labor, Ford helped usher in what was ultimately the principle of mass production; using those machines to produce large quantities of standardized products — an era that came to be known as the Second Industrial Revolution.

Today, more than one hundred years since Ford made his industry-defining statement, 3D printing is making its way forward in the mainstream and is allowing anyone to create customized products on demand at affordable prices. No longer do products need to be the same; we can now tailor products to meet our individual needs at little or no extra cost.

Are today’s digital manufacturing capabilities making standardization obsolete? Could we possibly be on the verge of replacing mass production altogether? Are we sitting on the edge of the Third Industrial Revolution?....more
