Gun control in the future.

BattleCorp

I can't claim ownership of this idea but I thought it was interesting.





In another forum there was a discussion on gun control and one member said that gun control in the not too distant future will be near impossible because of the invention of 3d printers.

3d printers already exist but are prohibitively expensive and not that advanced yet, but they will be shortly.

All a person would have to do to obtain a firearm is download the drawings of the firearm and print it out piece by piece using a 3d printer. Of course it would be illegal to do so and I'm not looking forward to the day where anybody can make their own guns, but it isn't too far away really.

It would be the same if you needed a spare part such as a new firing pin etc. Download the drawings and print yourself a new one.

It would work the same for car parts or pretty much anything you wanted to make. If you have the drawings, you can make it.

I know it seems far fetched now, but I'd say we'll be facing that in the next 5 to 10 years or so.

Anybody any thoughts on it?

From what i seen with 3d printing is that yes you can print the basic shape of the part or gun ,but it would be like a a toy gun ie no moving parts and the barrel would not be capable of firing a round ,it wouldn't be clever to try fire something that wasn't proof tested either,you can make a basic gun now in a machine shop ,if a criminal wants a gun lets face it he can buy one or rent one for small money ,it is a lot easier to get an illegally held gun than get a license for a legally held one.

All guns are different pieces put together so a 3d printer would be able to make the gun in pieces all ready for assembly. That would cover the moving parts.

I agree that a 3d gun made now would be unsafe to fire as the technology isn't good enough yet, but where will we be in 10 years time with the speed of advancement with technology.

Rudimentary guns can be made in machine shops, but it's very difficult to make an AR15 or something similar. A 3d printer would be able to knock out pretty much any shape.

At the moment, the 3d printer can make any shape it wants out of paper. It won't be too long before it can make any shape out of steel or other such materials.

Criminals will always have access to anything they want because they are willing to break the law to get it. I dont think 3D printers will be affordable to the general public in 10 years, more like 30-40

I believe that 3d type of printing is called CNC machining. Anyone with the right tools can make/copy a gun but in small quantities it's prohibitively expensive and complicated. In large quantities it's a different story, do a search on Norinco to give you an idea.

Come to think of it, "gun control" or better organised licencing and possession is really something that only applies to highly organised society. If you take a proverbial ramble through most third world or Middle East conflict zones and there's no shortage of those you can probably get your hands on an AK in some shape or form quicker than on a steak dinner.

Was thinking the very same myself, and did not post in case i was missing something obvious.

CNC machines currently "copy" parts now. They are also seriously expensive. So i see no difference between it or waiting 10-40 years for a different type of machine to do the same job.

Copying parts would not be my concern. Using current "scrap" parts to make firearms would be more of a concern. Making one type of firearm into another which would be as illegal as what is described above.

Interesting idea alright and it will be interesting to see the way 3d printing goes. But in my experience, the one thing criminality does well is stick to the KISS principle. There is no shortage of make shift, back yard, concealable, one use and reloadable (albeit slowly) rimfire and 12/410 guage weapons being produced in this country.

Agreed. The quality control in the materials and workmanship wouldn't be the same as you would get in a gun smith's. The gun smith would be working with forged steel, that most others wouldn't be able to replicate. Potentially, Joe Bloggs would make parts that would shatter after one, ten or a hundred firings, throwing lots of pieces of hot metal into his face.

He might also have to go through an awful lot of printer heads.

Where I last worked they had some pretty nice CNC machines and I can tell you that as well as the machines you need someone pretty handy at telling the machine what to do! The CNC part of it makes it sound nice and simple, you get your design and write it up in whatever program it is CAD or SolidWorks or whatever and of ya go. Thats what the design guys did, then give it to the fella who "drives" the machine and he would spend ages tweaking the program selecting which tooling the machine needed for certain curves and bores etc. Def not a simple process.

don't know anything really about 3D printing but Wiki has this about printing a gun:

Gun Control is only about keeping guns out of the hands of law abiding citizens, you don't need 3D printers or CNC machines to make firearms. I have handled perfectly functional firearms made by the Viet Cong in the early sixties and excellent copies of quite modern firearms made in Pakistan and Afghanistan, it is not rocket science to make a firearm, indeed schoolboys in the UK during WW2 made stenguns in metalwork class, likewise, the Singer Sewing Machine Company in the USA made rifles for the US Govt. Gun Control is really about people control not about guns.

I have often spent days tweeking a program to get it right , your dead right it is not a simple process once the parts are intricate ,thats why on cheaper firearms the parts are just cast and then polished up then they break fairly easy, Turkish guns are a prime example

rowa

A huge amount of the small gunmakers in england and belgium made the guns by hand in victorian times, forgings would be bought in and they were filed to shape, machinery was expensive where as labour was cheap.
A method of 3d printing is in developement in america that will use metal, it will probabily only be zinc based pot metal with a low melting point, and cnc machines have been around long enough now that second hand ones can be picked up cheaply, i have also seen manual mills converted with stepper motors etc to dual use cnc/manual.

As part of an industrial process. They didn't change from sewing machines to rifles without a lot of changes to equipment and training.

After having a look at Defcad and their founders message I would think Cody Wilson is right.
Its not about whether you can make the gun,its about the knowledge base out there to do it.
As he pointed out the proposed magazine ban in the USA is now ludicrous as they have supplied the CAD programmes for the "Cumo and Feinstein " High cap mags as freeware for all to share. What is a magazine really but a box with a spring in it to load the bullets,IOW a pretty simple thing to CAD programme.

You can now get a 3D printer for appx 600 USD[remember back in the 1970s Bill Gates I think it was, saying home computors would be really unaffordable for the average Joe and a 30mb would be all we ever need?] and falling that prints out somthing like that no problems.
True it might be a very shoddy printed copy,but like anything us inventive humans will sit down and think how will we better this technology in our basements?And THAT is the whole concept of Def cad.

The AR15 lower is now holding together to a ppx 1000 round shot count,they also now have an all plastic.22lr prototype pistol in the development stage and need appx 15k worth of R&D and programming to get it operational.
Thing is the theory is great and the concept is proven,but at todays technology level we dont have any of the liquids[? ]I suppose to print out a piece of polymer or whatever that will take the pressure or pounding that gun barrel steel will.

IOW yes we can print out mags,lowers for AR15,even frames for Glocks and 1911s,possibly some small components like triggers,pins etc but we cant print out barrells, bolts,bolt carrier groups,or even springs!
Thats still in the"Cyberdyne Systems" leauge of things.:P

I reckon when whoever develops that kind of liquid.The liquid itself will become a either for govt use only or restricted from sale to the public and thats where they "might" have some gun control in the future.
However,like even PGP encryption which Uncle Sam wanted classified as a unshippable defence product outside CONUS a civillian version will get out there eventually.

But even on todays line of things so long as people have access to hand tools junk piles and determination aquiring a firearm is really a matter of wanting one.I think anyone here who the most basic gumption if need be could build a homemade gun within 48 hours.OK,its not going to be a bespoke firearm as we know it ,but it would be sufficent to fulfill whatever needs we would have.
Guns have been made in high security prisions and even in the Warsaw Jewish ghetto.
Heck,we made them in Ireland throughout our history ,ever since Garrett Mor Fitzgerald brought in a pair of matchlocks.:P
I've seen homemade revolvers made here by blacksmiths form the 19th century,while cumbersome and not very elegant worked very well.
Even up to the start of NI both sides made improvised SMGs called Ulster funnnyguns or Harland&Wolff specials.

ou mean they made basic pressed / stamped / drilled metal parts? Not the breach or the like?

Nope ,assembled them. STENS are extremly crude but effective,made mostly out of stamped parts that can be hand made if need be.Its still one of the most favourite designs for underground manufacture. About the only machined parts are the bolt , barrel trunion, and barrel. If you have a few machine shops running those of by the thousand fold and another plant stamping out the other bits,you just need somone to fit it all together and another to tack weld the reciver and mag well.Somthing any 12year old could do.

As part of an industrial process. They didn't change from sewing machines to rifles without a lot of changes to equipment and training.

True,but while maybe not as fast as the STEN went from first concept drawing by Messers Shepard and Turpin at their dining room table to first off the production line Mk1 was somthing like eight /ten weeks.

It took somthing like four months before companies like Union Switch co,Wurlitzer,Rockola,Singer,etc had retooled and rebuilt plants to start cranking out Garands and M1 carbines by the crate load per hour.
But it wasnt an entire process,each plant came on stream in that time period,not all at once.But that applied for the entire American war industry be it from boots to bombers on a 24/7/365, no coffee or lunch break mindset.

The stench gun was mass produced by a company most of us old gits will recognize , lines bros ltd aka triang toys , makers of meccano etc.

3d printers already exist but are prohibitively expensive and not that advanced yet, but they will be shortly.

Depending on the model (and it's capabilities and the materials used), the cheapest is currently about $500 in kit form, but most "cheap" models are in the $1000 area. That's less than a new computer (well, less than a fancy new computer anyway).

All a person would have to do to obtain a firearm is download the drawings of the firearm and print it out piece by piece using a 3d printer.

Yes, but just 'cos it's easy doesn't make it legal, or ethical.
(Not to mention, any idiot who fired a firearm with unproven components that close to his or her face, would be a prime candidate for that year's Darwin awards).

It would be the same if you needed a spare part such as a new firing pin etc. Download the drawings and print yourself a new one.

That's why NASA is doing research on these things too - a mars mission that can make its own spare parts on the fly would be a great thing for them; think Apollo 13 but instead of engineers sending up fifty-step instructions for bodging a CO2 scrubber out of whatever parts were available, the crew just print off CO2_Scrubber.part on the printer and plug it in.

Anybody any thoughts on it?

It's not going to take over from traditional manufacturing, but prototyping, DIY, and other niche markets are going to be wildly affected. As to firearms - no, not for quite a while yet. And even if you finally get a 3D printer that could print a firearm, well, we already have laws that cover that; you'd have an unlicenced firearm, that's seven years in prison and enough of a fine to force you to sell the printer. I really don't see a problem here to be honest.

It's not going to "revolutionise the manufacture of deadly weapons" - I can go to the knife drawer in my kitchen and take out any one of twenty of those and nobody cares very much.

It might revolutionise IQ tests mind you - just watch A&E for anyone showing up with bits of 3D-printed gun embedded in their face and write "Idiot" on their chart...

yubabill1

Funny, I always thought "gun control" meant trying to keep on target!

InTheTrees

I have a little experience of 3d printing and the technology is still an extremely long way from producing a viable firearm.

The best that they can do now is magazines and some low stress parts.

As has been pointed out, machining a weapon at home is the same principal and a lot easier at this point in time

Grizzly 45

A very good and short documentary of this whole topic.

http://documentaryheaven.com/3d-printed-guns/

session savage

I am an industrial designer by trade and have some experience with this technology.
You can presently use one of many different CAD programs and draw anything you want and email the drawing file to a number of companies that will print it out and send it to you. The detail possible would allow for a fully functioning handgun and could be drawn and printed pretty easily BUT the materials available are at present nowhere near strong enough for the gun to be in any way safe. Granted thermoplastic technology is really coming along but I doubt you will ever be able to fully print a viable gun. I reckon the heat exchange even from a sub sonic .22lr round would be too much for any currently available materials.

Gas operated airguns....now thats another thing altogether. Scary to think of actually, anyone can at present print out a viable plastic air powered handgun...invisible to metal detectors :eek:

Grizzly 45

TBH the .22 all plastic handgun was done back in the 1980s to prove it could be got thru airport magnometers. Belive a guy called Bill Holmes from Arkansaws who was a custom gunsmith built one for the CIA.
Not that it was designed to work for a lifetime like an all metal gun,it was somthing for assainations or hijackings. IOW maybe 20 shots tops.Apprently the gun that John Malkovitch used in the film " In the line of fire" was based on the Holmes design.
Its one reason this SEN Israel is trying to bring back a bill that has been in suspended animation since the 1980s called the plastic firearms bill.This first came about when the "all plastic Glock":rolleyes: appeared and the anti gun nuts were screaming that Glocks could be got thru Xray machines and metal detectors by the dozens.
So I'd still be doubtful anyone is going to print up a fully working 3D gun for a long while yet.Especially when it comes to somthing like pressure bearing parts with bigger cals than .22lr shorts.

I am very disappointed in Today with Pat Kenny’s unbalanced reporting of the gun control debate in the US, in the wake of the Connecticut massacre.

There was no-one to speak for the Republican viewpoint and the report ended with Graham Finlay slandering every right wing gun owner in America, saying they were a pool of home-grown terrorists.

Thats pretty bad of rte but not unexpected , after all they have the joe fluffy show. but the british media are unreal in their "holier than thou" attitude to the american gun control situation, if they interview someone who is pro-gun they badger them and question why anyone would want a gun , if this doesn't work they cut the interview short. Gun control is part of the politically correct, right on liberal agenda.

Quite frankly RTE hasnt exactly been neutral on firearms issues on either TV or radio,I wonder then why should I pay a TV /radio liscense to have to listen to the one sidedness of a liberal anti gun media on our national airwaves,especially one that attacks my lifestyle??
I for one am stating RTE can stuff their demands for my TV liscense where the Sun dont shine,and if Comrade Rabbit thinks he is getting 150 quid out of me for having a computor or whatever,he'll get the same response.

A reciver made of car exhaust pipe,loads of tinney stamped metal parts,tack welded together in a toy factory.A brass/bronze occasionaly cast in those materials bolt head.'Bout the only steel in the whole gun is the breech and barrel.

3D Printing is still in its infancy yet and very expensive but in countries where Gun Ownership is tightly regulated it will probably become more of a problem as people who would typically be unable to get their hands of weapons find that they can just manufacture them at home for themselves instead. Criminals will probably still have their own ways of obtaining weapons but what would stop a few teenagers from printing out their own gun and taking it to school which is the sort of scenario concerning people in the article.

Cass

While recognising that it can be done i seriously doubt it is anything to worry about. Most of it has been covered in this thread.

The guy in the video fired one shot of .22 rimfire. About the least pressurised cartridge there is. I would like to see someone try that with a .38, 9mm, .40, .45 or even .50 cal. Also to be able to fire more than one round. The printed guns are not shotguns or rifles, and if someone got a printer, and assembled the parts it will never stand up to the pressures of a rifle round. When you consider shotguns, and rifles can have up to 60,000 PSI at the chamber. It's a no brainer.

Some will argue that if a criminal wants a gun they can print them off. With a cheap machine going at €8,000 it's not exactly "cheap". Then there is the design. The one in the video is a basic chamber/firing pin/trigger assembled in the most basic of frames. However you need to be proficient with computers, and programming to make the machine print one off or have access to design specs from existing manufacturers which is neither easy nor cheap. So get one part slightly wrong and rimfire or not it's goodbye hand(s).

The other issue, and while some may believe this will not be an issue i disagree, is accuracy. The barrel is not rifled so it's basically a smooth bore and anything after 10 feet is dead safe. notice in the video they did not show the target or the distance he was shooting at. Even from a criminal aspect you want to hit what you are aiming at.


Lastly, if they do clamp down on 3D printers, and control/monitor them even stricter than real firearms - so what. As no law abiding person will be using one or wanting one what does it matter to us? Not being flippant, but seriously how will this affect us. They talk about printing off pistols. It's illegal from the start so not going to affect us.

Well, I'd like one. Being able to make spare parts for bits that break around the house, being able to run off trophies for matches, being able to make up parts for robots, being able to print off chess pieces, that kind of thing would be neat.

But you print off a firearm and it's the same thing as making one through traditional means - do it with the appropriate paperwork and licencing and all's okay; otherwise, it's highly illegal and equally detectable regardless of methods used. So banning 3D printers wouldn't help.

Sparks wrote: »

Never said to ban them. I said if they were to monitor/control the sale of them.

As for buying one and using it for parts for household items, and non firearm uses well that it the point of the machine is it not? All completely legal and above board so not even an issue.

Then using one to legally make a gun. Well whomever likes can have my one. I'll stick with the metal variety. I value my face, and hands.

Exactly , plenty of lads with lathes and milling machines in their sheds into restoration or model engineering etc and there hasn't been a spate of homemade guns produced. Though the home office in the uk were going to try control or have a register of machine tools as they could be used for gunmaking, they came to their senses and gave up the idea as unworkable.

There was an item on this in the Morning Ireland programme on RTE Radio 1 earlier this morning, I'm sure it'll appear online in due course.
Allegedly, the gun being discussed is chambered in some flavour of .38.

The local 'expert' mentioned that these printers can be used to make plastic parts for AK47s and M-16s, to audible gasps of incredulity in the background :rolleyes:

Then there will be a fine black market for unregisterd 3d printers..:D:D:D

8000 euros for a printer??Try putting one together for about 400 USD! That does the job maybe alot slower,but just as well.
Like anything the technology will become cheaper as the demand increases.
Remember how much the first computer,DVD player and flat screen was??
BUT
It doesnt matter as no matter what at this level of technology until someone develops a liquid steel that will go thru a printer nozzle that can withstand the continous pressures of a cartridge going down it,or slamming into it all this will do is print out non pressure bearing parts.
So along with all the other good stuff we are supposed to have by now,like hover boards, personal jet packs,personal robots and phasers.:D This is still in the scifi side of things.

They are talking of trying the so called "Luty project" next.This is based on a chap who developed a DIY SMG in the UK in the 1990s,called PA Luty.[Google it for the whole story].
This is going to be a as much as possible plastic SMG. However,I still see metal no matter what in the design,like barrel,bolt and firing pins etc.

As for this "Liberator" pistol,it still isnt all plastic,it still needs a steel barrel insert.
It is a concept gun based on the ww2 throwaway all metal single shot Liberator pistol that the Allies dropped by the thousands all over occupied Europe.Idea was it was simple to use,sneak up on a German soilder ,shoot them with this and liberate their rifle and equipment.
Now before the screams of aghastness arise that this is a new massacre weapon that criminals will be making in their millions.
Dare I suggest that for somthing that is an up close and personal weapon it has a lot of disadvantages.
1] You still need ammo for it
2]You need a at least thousand euro 3d printer
3]You need to know how to read and use CAD
4]Its not totally undectable with a metal detector and properly trained security personel due to its metal barrel insert.
5]You could put together a halfway decent improvised firearm at home for a quarter of the price of all of the above using normal house hold tools and materials.
6] The distance that this is effective.IE phone booth or card table range.:pac: You might as well use a bit of lead pipe,a ball pein hammer or a good meat cleaver for better effect.:rolleyes:


So still no matter what,it is still very "Star Trek" to belive that within the next few years this will be capable of producing a full ,safe all plastic gun.

I wonder what heat dissipation would be like. While plastics tend to have a higher specific heat capacity than metals (typically 3 times that of steel), they also have lower conductivity (typically steel is 500 times more conductive) and melting points. And then there is ignition temperature.

Grizzly 45

The current liberator pistol design is a single shot,so there isnt any big rate of fire going thru it.
Still at the momentit has a steel barrel or barrel insert,so not going to get away from that part.:)
Be more intresting to see how they intend on the Luty project around the wear and tear of the battering a full auto bolt will be subjected to,and how they will produce the required weight for this to function reliably.
IOW until liquid steel is available for these printers.Heat dissipation is not going to be a big problem.

As for other polymer plastic pistols currently out there.Yet to hear of a glock melting or bursting into flames.:D

All this just helps prove the point that gun control is futile if the intent is to keep criminals from owning guns. If the intent is to heavily regulate law abiding citizens, then gun control is the ticket. Not that the printer folks are crooks mind you. But like the home computer gives every owner the power to design and compute to levels previously possible only for a mainframe, we are increasingly able to manufacture stuff in the garage, basement & the individual shop.

As to the Liberator, interesting concept and just about as impractical as most of the experimental stuff in this thread. Kind of a good place to circle back to in this discussion. Very little evidence of them having been supplied anywhere in numbers except Pacific / China-Burma theater, and precious little information on that. Very little evidence of their actual use anywhere anytime. More of novelty perpetrated by the black ops idea guys of the WWII era, one of many misdirected well meaning ideas. I got one because my uncle who flew the hump in C-46s appropriated one as a gift to my dad who built the runways (a good and enterprising Irishman my uncle, he ended up running a shipping company after the war).

3D Printing is still in its infancy yet and very expensive but in countries where Gun Ownership is tightly regulated it will probably become more of a problem as people who would typically be unable to get their hands of weapons find that they can just manufacture them at home for themselves instead. Criminals will probably still have their own ways of obtaining weapons but what would stop a few teenagers from printing out their own gun and taking it to school which is the sort of scenario concerning people in the article.

I checked local 3D printers but:
