The first metal gun printed on the 3D printer

88

Half a year has passed since the plastic “World's First Fire Gun, fully printed on an 3D printer” was introduced. And here engineers from the Texan company Solid Concepts for the first time in the world printed a metal pistol. They did this to demonstrate the capabilities of modern industrial 3D printing and do not set a goal to make technology available in every home. However, sooner or later it will inevitably happen.


For the demonstration was made cult gun M1911, created by John Browning. This is the first self-loading pistol, which began to be used in the US Army, before that they had only revolvers.

Pictured: A working copy of a M1911 self-loading pistol developed by John Browning. The gun was in service with the US Army from 1911 to 1985 years.

Parts of the gun are made by the method of direct laser sintering of metal (DMLS), the same method that NASA uses to print rocket engine parts. Only the springs were made separately. After printing, the parts were polished and fitted to each other by hand.

During tests, the gun proved high accuracy of shooting.



Representatives of the company say that they printed the gun not to make this process cheaper and more accessible to every man in the street, but simply to demonstrate the reliability of parts manufactured by the DMLS method. Metal printing equipment cannot be bought for less than $ 10 thousand, which most 3D print enthusiasts cannot afford. The company itself Solid Concepts used an even more expensive industrial printer, see video.



Solid Concepts is licensed to manufacture weapons and promises to produce within five days and send to the buyer a set of 3D parts for assembling a pistol. Naturally, only a US citizen who has the appropriate permission can make a purchase.

“Our pants-gun expert released 50 charges and hit several silhouettes in more than 30 meters. The weapon consists of more than 30 preprinted stainless steel components 17-4 and Inconel-625. It is completed by a selective laser-sintered (SLS) three-dimensional laser grip. ”

“The whole concept of using a laser sintering process for three-dimensional printing of weapons from metal revolves around evidence of reliability, accuracy, ease of use for printing metal functional prototypes and end-use products,” says Kent Firestone. “It is a common misconception that laser sintering is not accurate or durable enough, and we are working to change technological prospects for humanity.”

Another common misconception about three-dimensional printing is that it is limited to desktop printers, which can only squeeze plastic threads.

For the sake of debunking all the myths and misconceptions surrounding the three-dimensional printing, the engineers built a technology demonstrator, no doubt. Leaders will no longer be able to pretend and diminish the prospects of this industry.

Laser sintering is one of the most accurate manufacturing processes available, with an excess sufficient to create interchangeable, requiring tight tolerances of the interacting parts of the gun. Printed metal surpasses precision casting in terms of porosity and machining accuracy.

Weapon rifles were built, or “grown”, cleanly, without being further machined. Hand tools are used only in the decoration, without affecting the mechanism obtained solely through printing.

        Despite the fact that the 3D printer of the new budget generation - Bucaneer - can already be bought for only 400 dollars, many users are not happy with such a low price. And so the search for solutions continues
        .
        Now Matthew has already thought about improving the technology for producing freebies for 3D printing and is building a machine for processing plastic bottles into a thread for an 3D printer.

                  Polishing of the external curved surfaces is carried out on a robotic complex (mechanical hand, trajectory of movement - according to the program), followed by sorting of the blades by weight.
                  We tried to make some parts from a heat-resistant alloy with an intermetallic core. Finishing is indispensable.
                  Your link describes a part for a rocket engine, not an airplane turbine (as in the video) this time, and secondly, it does not say that the part obtained by this method is completely ready for use. As for the treatment of the internal hidden cavities of the injector, it is possible that they really are not processed.

          Using a slightly simpler device, Soviet engineers cast cement houses. Well, more precisely, it turned out not cement, but a puff cement film, a kind of bulk iron. In strength, such a house was approximately on par with 20 steel. But the Soviet leaders were no longer able to realize the advantages of the method. Brains at that time were already considered a crime in the USSR by themselves.

            The way you change is smooth.
            The restructuring of equipment is more inertial than re-profiling personnel into more human, less monkey sites. Under capitalism, it will result in benefits for extra people who are not counted. With socialist planning, it starts up to reduce the working day, culture, health and other social security.

    So progress has come to print in metal. Although the printing capabilities in terms of accuracy and internal structure of the final product are still limited (roughness, porosity), but this is already a big step in mechanical engineering technology, many of those can be replaced. operations. Final machining is still necessary, in the video, the thread in the pinion hole is cut with a tap. Now, when the next message on the topic of printing weapons on a 3D printer appears in the news, it is necessary to clarify whether this is a printer for metal or plastic. A plastic printer can be bought over the Internet almost freely and not expensive. I hope the printer for metal will not be so easy to purchase, most likely its price will be comparable to the cost of a good modern metal cutting machine and only large enterprises will be able to purchase a printer.

    This is probably why, to compensate for the porous structure, a viscous material was used - stainless steel, so as not to burst immediately.

      Not certainly in that way. There are other machines)). A good thing, of course, but for the machine to pay for itself, it must work in three shifts without a break. And do not forget that a qualified operator (able to compile a program and minimal setup) is very expensive. And repair and maintenance of CNC machines by an authorized dealer costs a lot of space ... the truth is, of course, they are of high quality.
      Due to the enormous price of most CNC machines, in Russia, machines mainly from China and Taiwan are popular.

        At European prices, the operator of such a CNC machine costs about 3000 Euros.
        In Ukraine, such a specialist is paid about 1000 euros.
        For one reason, that he is not a milling machine operator, not a turner, and not a designer - he is engaged in entering programs into the machine controller.
        It is cheaper than a machine park and a crowd of turners and milling machines.
        This machine costs about $ 870000. Having made, for example, 2000 monolithic aluminum appers for AR-15 at $ 600 - the machine will already break off and make a profit.

        For a long time already in the world, people have been assembling CNC milling machines, in the CIS there are quite a few of them. You can say on the knees they collect, some of which achieve amazing results. Stepper motors, servo drives, high-frequency motors, etc., everything can be ordered in China by mail, so on average, a small machine will come out in 2-5 bucks. Depending on the program, and this would be the most important thing, the cutters can handle any material.
        Here is an approximate video, I think that over time and 3D printers will be able to collect.

    This is probably really a breakthrough technology for very many years, all the screams about the fact that energy is consumed. low quality, impossibility (for now) of some operations, all this is garbage .. this is just the beginning of the journey. Let me remind you that once an aluminum spoon was worth more than gold! Give a little time for 5-10 years, everything will be the way. There is such a thing about the quality of things .. there are some, but there are many reasons and the main thing is marketing tricks, but not as an imperfection of technology. for example, you’re watching a movie, not from a VCR, but from a DVD or from a network, so it will be in this case, but the quality will be different depending on the tasks. We’ve said an engineer a long time ago we can make an eternal electric drill, but it will cost as car .. and who will need this? only in narrow areas (space, military, researchers are different)

      Yes, damn it is not the price, But the fact that long-term businessmen is not profitable !!! About aluminum, well, it was like that, but some that previously had, if not ubiquitous, were many, but now they are worth a lot of money. By the way, it’s not a fact that when a certain level is reached, they will not start promoting another, and this is not at all because the old had no prospects and the dough cannot be cut down.
      About the VCR I had a friend of the military who graduated from something related to devices (I don't remember how long ago it was) and so he said that for the specialists there was such a video recorder, where a film was used as a carrier as on a computer, and so he "tore" all civilian crap even Hi-Fi class. Forgive me about the disks, but this is also the technology of yesterday's day, even all sorts of blues and so on, for a long time (although it seems like the Americans claim that only one, etc.) is shorter as a carrier of a single crystal of quartz and forgive the technology of the 80s if not earlier, just the difference between us and entimi, our business is doing, and they immediately think of commerce - what to take from them.

        Everything is much simpler. Take yourself a drill not of a professional series but of a industrial series, and if you don’t feel sorry for the money, then you are obviously a client of the Hilti company (Germany), if you didn’t get a normal drill from them, it’s obviously not about 25.000 rubles. Or a native prom from Metabo.

    Uv. comments and readers. Can't you see that this is just PR. It is simply impossible to create a real pistol, taking into account the necessary requirements, using the above technology. By infe, they shot 50 rounds, and they say "everything is great." To check a working layout, it really is necessary to shoot several thousand cartridges, and then omissions and problems emerge. Let me remind you of this fact. When two or more samples of weapons show the same results in the competition, the winner is the one with fewer parts and parts, as well as less work / hours.

    It’s not a matter of the gun. These are new technologies that can be used to create parts of a very complex configuration, and even not very expensive. You can also create composite compositions that cannot be obtained due to the non-meltability of some metals. By strength, they can greatly surpass ordinary steel. You can include antifriction or other additives in the metal. Not on home printers, of course. This is a very promising direction for the development of new technologies.

      I can't honestly say about the model, but I can only say one thing that was not particularly widespread in the army, since my acquaintance, although a soldier, is, let's say, with specifics, so there is every reason to trust his words, and besides, another a former instrumentation engineer, when he heard about it from me, he immediately caught fire, as he understood what it was about. And still it is not necessary to write off the fact that every device has a "character" and the staff also treats devices in different ways. It means that yours were simply not lucky, but mine were lucky.

    I read it, I thought ... I largely agree with Asan-Ata! There is powder metallurgy, but not in pure form, but in heavily stripped down. The classic powder technology is carried out by sintering under heating and pressure. And the combination of these two factors gives the necessary physical. properties (wear resistance, tensile strength, bending, tensile, torsion and shear). In this case, we have sintering only when heated. The detail will be porous, with an obscure crystalline structure and many stress concentrators!
    In short, for the production of irrelevant parts ... Like the chess in the photo, or the gear knob. True, you can make details of complex shape "+". Until this technology comes into mass production due to cost (I will especially emphasize the word while). This article shows the technological capabilities of the development company, and the pistol is a good example. Its parts are quite complex in shape, and loaded when fired. But the resource will be clearly lower than that of parts made by conventional metal cutting! Another example is the gear in the photo. The workpiece has a rather complex shape, but the teeth need to be ground, hardened, normalized, and ground again. After that, the part becomes a gear! And I doubt that the sintered material is able to withstand such "bullying" during manufacture, and even greater loads during work. Well done guys ...

    If we take into account the factual, for example, the guaranteed number of thousands of shots for the PM barrel is guaranteed, then it turns out that it is impossible.
    At the expense of the blades for turbines (?), It is possible that they are made. Just do not forget that for the military-industrial complex industry, a whole line of DISPOSABLE turbines are manufactured, which have less stringent requirements, in contrast to permanent ones.
    The link in the material to the tests of the ts pistol "weapons expert" does not stand up to any criticism at all. After firing several shots of a pistol clamped in a clamp, without disassembling it and thoroughly examining it for defects, the "expert" starts shooting at targets from his hand ... Forgive me, not an expert, but a footer. There is nothing to discuss. Continuous "blizzard", earlier called eyewash.
    P.S. Pay attention to the condition of the side cutters when they bite off the particles. For me, this is an indicator.

    It is cheaper than a machine park and a crowd of turners and milling machines.
    This machine costs about $ 870000. Having made, for example, 2000 monolithic aluminum appers for AR-15 at $ 600 - the machine will already break off and make a profit.

    Is this the price of a machine on a price list? Then do not forget the cost of customs duties, shipping costs, and commissioning. It is generally accepted (at our enterprise), for example, that the cost of commissioning is 10% of the cost of the machine.
    We flew the spindle on a Mazak machine, they waited almost 3 months until they brought it and installed it. About the cost of this site, I generally keep quiet.

    Solid Concepts continues to test the world's first metal gun printed on an 3D printer. In just a few days, more than 600 shots were made from it, the barrel and receiver perfectly withstand the pressure of 20 000 psi. The firing accuracy remains as high as at the beginning of testing.

    Although an industrial DMLS 3D printer costs several tens of thousands of dollars, on the other hand, friends or neighbors can save up to buy a used printer at an eBay auction for about $ 10 thousand. It can always be used if you need to print the same engine for a car , household utensils or weapons.

    American laws guarantee a citizen the right to make weapons for self-defense; no license is required for this. In Russia, such a printer can also be printed, for example, with a knife.

    Powder metallurgy cannot, I think, give the whole spectrum offered by "ordinary metallurgy. For example, an ordinary ball water valve made by the powder" method ", if it does not break during installation, then in a year or two it oxidizes along the entire section and falls apart. the method takes place, besides, not the most complicated pistol, compare at least with the “Luger.” In addition, the cost of both 3D printing and the subsequent high-tech, which I have no doubt, the processing will be equal in quality and cost at least not soon. ”For me, it's better from a GOOD RENTAL and the traditional method.

    Based on the open printer RepRap made a printer that can "print" from metal. Already, it will be more profitable for American families to make many household items on home printers than to buy, in addition, they will spend less on natural resources.

    The printer is a modified RepRap, in which the Millermatic 140 argon welding machine was installed as the printhead. The cost of components according to Pierce's calculations is about 1200 dollars. The most expensive parts are a welding machine (price in Russia ~ 32000 rubles), a microcontroller board and thick aluminum plates.

    Ghost Gunner 3D Printer: Legal Printing of Firearms at Home
    vooruzhen.ru/news/98/7635/
    This $ 1299 printing device allows you to make the basic structural element of a semi-automatic rifle at home.
    The manufacturer not only managed to quickly find buyers for the third batch of "ghostly" devices, but was also forced to increase the cost of products from $ 999 to $ 1299.

    The printer is capable of manufacturing a key component of firearms, which, unlike the official carbines, will not have any individual serial rooms, nor need permits. The wearing and use of a partially printed rifle in the United States is not formally prohibited by law, although it causes a storm of protests among disarmament civilians.

    The resulting lower part of the receiver although it will require some artisanal refinements, however, in general it is an element ready for 80%. “Just follow the instructions to print the mechanism, and then work a bit with a screwdriver and become the owner of an oversized firearm in one day without leaving your own home,” reads the inscription on the developers website.
