The American firm Solid Concepts announced the improvement of the technology of direct metal laser sintering, reports Lenta.ru report with reference to the site «3D Print».

In the US, "printed" a new gun on the improved technology


During the testing of the new technology, a “Reason” pistol (“Argument”) of 10 mm caliber was “printed”. It is based on the army "Colt 1911". A feature of the sample was the high detail of small elements. According to the site, "on the trunk of the" Argument "is" engraved "the introduction to the US Declaration of Independence."

“The pistol received metal cheeks of the handle with a wavy pattern. On the slide frame during printing was applied the name weapons - "Reason". In addition, the same method on the gun "printed" details about the manufacturer ", - stated in the publication. What metal was used for this is unknown. Detailed information about weapons on the official website of the company has not yet been.

The first “printed” metal pistol (an exact copy of the “Colt 1911”) was presented by Solid Concepts in 2013. They called the weapon “1911 DMLS”, its caliber is .45 ACP. According to the site, this gun was made "of stainless steel 17-4PH grade powder and 625 brand inconel." The tests were successful. Manufacturers indicate that "so far more than five thousand shots have been executed from it."

The company put up one hundred copies of this pistol for sale, setting a price of $ 11,9 thousand per barrel. How much was sold - not reported.

“With direct metallic laser sintering, or DMLS, metallic powder (stainless steel 17-4PH and 17-5PH, inconel 625 and 718 or titanium Ti6Alv4) poured into the container, melted into a uniform structure. "Printing" is carried out in layers, with the thickness of each layer is about 20 microns. After each melting, a special device sinks the “printed” layer into the powder, simultaneously applying a new metal layer for sintering over it, ”the publication explains the essence of the technology.

Parts made in this way do not require additional mechanical processing, however, it was impossible to manufacture them with a ready-made engraving or drawing. The advanced technology allows to "print" any elements, down to the smallest.

              Why not? The thickness of the sintered layer is only 0.02 mm (20 microns), this allows printing very small and very precise details, for example the same rifling in the barrel. and there is evidence in the article "on the trunk "Argument" "engraved" introduction to the US Declaration of Independence ".

          While this technology is far from the future. Very expensive, one-to-one production and poor quality. If this is a pistol, then there is only one shot, during the rest of the shots the bullet flies wherever it wants. Well, gunpowder and a capsule have never been made on a printer. And about who is the first is empty bragging. For example, the first mobile phone was created in the USSR in 1957 by the designer Kupriyanovich. America had never even dreamed of anything like it. She picked up this technology only when there was a microminiaturization of radioelements. Here Russia was not the first.

              Mock at the new technology - no matter how expensive it is! Previously, aluminum was much more expensive than gold, but with the development of technology - you yourself see what. Printing products on the printer is now in its infancy. But human thought does not stand still! And when this production method is debugged - it will not be ridiculed!

          Each product must have a certain quality of the materials of processing both the surface (for example, cementing) and the properties of this material itself, if it is not a homogeneous brick or pood weight.
          If you make all the parts of any product (an airplane or a drill) with the same material properties as in the current "old technology", then the complication of the system of such a printer will lead to the manufacture of any product, and so not very cheap, in the stage of very, very, very not cheap ...

      Oh, what kind of news is it right? lol For three years now, ours have been producing blades for aircraft turbines and similar products from titanium alloys. The production time of the product is reduced from a month to 3 days. They would have learned the mattress toppers, what is sensible to do, otherwise they advertise their "pukalki", which are 10 times more expensive than a simple, very high-quality pistol.

          And besides, it is necessary to remember that all these machines - this is, first of all, vibration-insulated foundations, precise mechanics, precision actuators. All this gradually wears out, loses accuracy, it requires periodic adjustment, calibration, cleaning, lubrication, etc., etc.

              .
              And they do this:
              - First, a monocrystalline semiconductor wafer is taken (today the industry standard for such wafers is a "pancake" with a diameter of 300 mm). Imagine a "pancake" made of a silicon monocrystal with a diameter of 30 cm and a thickness of 0.25 mm 8-))
              What is his area? - pi de quadttt ... - i.e. ~ 282000 mm * mm
              The average size of a typical integrated circuit processor chip is about 5mm * 5 mm (for server processors - more (up to 10 * 10), for discrete transistors and simple logic - much less (up to 1 * 1) ... But we take - average the size...)
              Total area of ​​the average LARGE IC of the 16-bit microprocessor / calculator type is 25 mm * mm.
              In total, on ONE PLATE in a SINGLE (!) Technical process (after about 30-40 technological operations) - 10.000 (!) Semiconductor chips are made AT THE SAME TIME (plate edges are not used). Those. each of these 30-40 technological steps is applied to EVERY (!) of 10.000 chips located on the original silicon "pancake". Physically, these operations take up to several days. Long? - yes .. But the whole trick is that in the most LONG time operations - such as ETCHING, OXIDATION, DIFFUSION (which last for HOURS) - NOT ONE such plate (pancake) is processed AT THE SAME TIME, but - at once a LOT (or even several (!) batches) of such plates - in quantities from several "pancake" plates - to HUNDREDS of "pancake" plates simultaneously ...
              - thus, in a few days (technological cycle) up to a MILLION chips are produced. And all the "overhead costs" of production for these few days are "smeared" over this million chips.
              - because of this fundamental PARRALLELITY of processing hundreds of thousands of chips - today "everyone" has both a telephone and a computer "
              8-)
              .
              And if each transistor of the chip (and there are about a MILLION of them on ONE modern chip 5mm * 5mm) - were drawn SEPARATELY (and technologically it is possible! - for example, an electron beam) - then in the same few days "they would not A MILLION chips - and O-DIN (!!!) - and this at about the same costs!
              - i.e. the cost of such a chip would be a million times higher.
              But in fact - not a million, but MANY MILLION times higher
              (
              because ANY equipment is periodically wrong. Imagine - we drew the transistors of the chip, for example, TWO DAYS, and then bang - and the failure of the e-beam "went away" and "cracked" a bunch of already drawn transistors and interconnections: that's all (!) - DRAW the whole chip FIRST. Since it is already IMPOSSIBLE to fix - and to destroy the chip - ONE (!) Error (failure) is enough
              ).
              “But a gun is not a chip. There is NO that accuracy, and single spraying errors - do not care. On extreme - if the DEFECT is VISUALLY NOTICE - then "polished" - and that's the end of it. But, nevertheless, this very pistol will be "drawn" (scanned-sprayed) by ANYONE SUT-KA-MI. Since about any PARALLELIZATION of operations when scanning-dusting - vashsche DOES NOT GO! And such a "printed" product will cost ON THE WEIGHT OF GOLD.
              .
              And this, alas, is a materiel!

              it is directed to DEEP ... So to speak ROOT of the process technology.
              .
              You see, sire, the material is handled by the TOOL.
              And therefore, PRODUCTIVITY (i.e. the cost of the product)
              1) the smaller, the smaller the area of ​​contact of the tool with the product
              2) the smaller, the thinner the layer of the product processed by the tool in one pass
              3) the smaller, the larger the area and thickness of the product that needs to be processed.
              .
              And for "scanning technologies" - ALL these indicators - they are simply "SHARPENED" to REDUCE labor productivity.
              .
              1) The area of ​​contact of the tool (printhead) with the product is MINIMAL (the smaller the area of ​​the head - the smaller parts of the product can be worked out with greater accuracy ...)
              2) The layer of the product processed by the tool in one pass is MINIMUM (as stated by the manufacturers - 20 microns = 20 * 10 ^ -3 mm). Estimate - HOW MANY PASSES should the "printhead" make - to "build up" a layer of material 1 mm thick? - 1/20 * 10 ^ -3 = 50 passes!
              3) the area and thickness of the product ("revolver" type) - by no means small
              Let's take, say, a "side pad" - like a parallelepiped with an area of ​​30 mm * 50 mm = 1500 mm * mm with a thickness of, say 5 mm.
              Let the head area be 20 * 20 microns = 4 * 10: ^ - 4 mm * mm (so that the head resolution in depth and "sideways" is the same). So on the area of ​​the "overlay" 3.750.000 areas of the "print head" will fit.
              .
              Now we calculate the time it will take for the "print head" to "create" our "handle overlay" in size (30mm * 50mm * 5mm).

              For one millimeter 5mm of thickness, you need 50 "layers" of "head" passes. In total, for all 5 mm - 250 passes-layers are needed, each of which "passes" -layers should consist of 3.750.000 "elementary points" applied by the "head" (20mk * 20mk * 20mk each). In total, to create a "overlay", the "printer" head will need to create 3.750.000 * 250 = 937.750.000 "elementary points" on the product (20mk * 20mk * 20mk each).

              .
              Now let's estimate the time: 937.750.000 "elementary points" * 0.01 sec = 9.377.500 sec.
              - in a minute 60 seconds per hour 60 minutes. Total per hour - 3600 sec.
              9.377.500 s / 3600 s = 2.604 hours
              2.604 hours / 24 hours = 108 days ...

      The principle is as follows: a 3D model is built, then this model is "cut into layers" and the 3D printer builds these layers one by one. So the hole should be ... if there is one in the 3D model. I am not aware of metal sintering, but powder printers can even print mechanisms with moving parts, i.e. from the printer you can get a ready-made mechanism in which certain parts will turn and turn ...

      3D printing technology is the same as saying, "The weather is good outside," and to say nothing more. Each part is machined with a corresponding milling cutter in a coordinate system.

            In the process of 3D printing, the principle of welding or gluing parts from a powder is just laid down.

            For example, welding, initially there is a powder (plastic, metal is not important), the laser sinteres the powder along the contour of the part layer by layer. Or bonding when the printer glues layers of powder with glue.

      First, a 3D model of our gun is created, then it is divided into large nodes, then a special program breaks the model into layers, and sends commands to the printer. The printer consists of either a powder reservoir and a laser carriage, or simply a carriage in which both the laser and the powder supply system, the laser sinter the powder in layers, the article states that the layer thickness is about 20 microns. After the sintering process, the non-sintered powder is removed. Details are collected. The gun is ready.

    If you believe the Forbes story (and there is no other information yet), the Liberator installed on the test bench can withstand up to ten shots, after which it shatters into pieces. As befits the inventor, Wilson personally, holding in his own hands, made at least one shot from his pistol. The answer to the main question - how exactly does a plastic structure cope with pressure and temperature beyond its control - is not yet completely clear. It is only known that after printing some elements (including the barrel) undergo a simple chemical and thermal treatment, which smoothes out irregularities and increases mechanical strength. However, waiting for an answer is not long. Wilson shared information with Forbes on condition of non-disclosure of some details, but today or tomorrow he promises to post the Liberator sources and assembly instructions on the official website of Defense Distributed (http://defdist.org/), the non-profit organization he founded that is engaged in the development of free printed firearms .
    It's time to take stock. First of all, we can talk about the creation of a new type of firearm: unprecedentedly cheap, affordable, simple, reliable enough, without the possibility of being tied to past owners and events. The printed “trunk”, of course, does not have a serial number and features (remember the grooves on the pool?), Which allow to find out where it was used before. And what's the point of using such a gun twice? Shot - threw it away. The ideal solution for crime circles.

          You probably don’t know about powder metallurgy.
          Powder production:
          Mechanical grinding of metals is carried out in vortex, vibration and ball mills.

          it is common to obtain powders of iron, copper, tungsten, molybdenum by high-temperature reduction of the metal (usually from oxides) with carbon or hydrogen.

            At the same time, a huge amount of metal is spent, part of which will go to waste.
            It is not granules that are sintered, but powders; the particle size in the powders is 1 to 100 microns.
            You probably don’t know about powder metallurgy.
            Powder production:
            Mechanical grinding of metals is carried out in vortex, vibration and ball mills.

                I found a couple of rollers with 3D printers on which to make gun parts. One shows how to make a mold for the production of plastic cups, and the other shows a gear:





                I doubt that this can fully replace all modern methods of metal processing.

                Take for example a high-quality barrel - the main part of any modern hand-held high-precision small arms. In a good trunk there are no elements unattainable for production on standard technological equipment. And the requirements for the structure and composition of the metal, linear tolerances and cleanliness of the surface of the bore are high - at the limit of the possibilities of metalworking and metallurgy. The 3D printer will not give such tolerances and does not meet such high requirements. This will especially become apparent in mass production, and not in the laboratory, in the manufacture of piece parts at the price of an airplane.

                I am not saying that such technologies have no right to exist; on the contrary, the future lies with them. It is only necessary to use them. Details of gas turbines, for example, on 3D printers are successfully done. Many parts of the gunner can also be designed for 3D printing, especially pistol parts. True, the cost of such a gun surpasses all reasonable boundaries.

                  Replace does not replace, but will find its place, precisely due to the lower consumption of materials.

                  So far, yes, but technology does not stand still. If, as it is written in the article, the printer prints layers 0.02 mm thick, then it is possible to produce sufficiently accurate and small details. True time is running out. I think in the future this technology will take root in repair shops and orbital stations.

                    I did not find waste in technology on casters. For the production of small powder parts, much is used in this type of 3D printing.

                    By technology. It is necessary to design appropriate machines for different types and dimensions of parts, which are optimal for the dimensions and type of parts, in order to achieve maximum accuracy in laser positioning relative to the table and the final accuracy of manufacturing the part itself. Everything is like metal-cutting machines: carriages, slides, table ... Plus, the volume filled with powder must be isolated from the movable guides and from contamination of the powder by extraneous fractions.

                    By the powder itself. It also needs to be produced in assortment and of high quality - a challenge for metallurgists and technologists. Even modern weapons-grade steels are produced slightly differently from structural steels. They are also more expensive to manufacture than conventional ones. "Grind" into fine powder "steel" will come out even more expensive. Cleaning plants are needed.

                    Many parts of weapons, in the production of which powder metallurgy is already used today, can be made on a similar printer. I do not see any special obstacles.

                    For some others, I do not presume to finally judge the prospects, but everything will have to be developed from scratch. Some types of metalworking still can not get rid of heat treatment (cryoprocessing), electroplating and other things.

                    This is my most optimistic forecast. If you solve all the problems, then the weapon can be released at a structurally higher level: lighter, more compact and accurate.

    I see the novelty has aroused great interest among the readers of "VO". Back in the 80s of that century, at enterprises subordinate to me (I was in charge of the State Administration of one respected Ministry), high-frequency connectors in all products of military equipment were manufactured by powder metallurgy. A computer and a rapid prototyping program were added here. In my monographs "Systems Analysis in Fundamental and Applied Research" and "Progressive Technologies in Instrumentation" we tried to present everything. The article does not show the labor intensity of the manufacture of this pistol, but for comparison, the labor intensity in operating technologies on metal-working machines. In general, impressive. I have the honor.

    Priozvoditeli indicate that "so far more than five thousand shots have been fired from it."

    Damn, yes 5000 shots is a standard test. What does it mean at present? Either the barrel sustained 5000 or not. And sintered steel is generally duper. The author is apparently not far off in technology.

    This is not in the article, but in the DARPA descriptions for competitions on the development of 3-printers ...
    In the near future, the main task of ZD printers in the US-NATO army is to print spare parts for weapons directly at the place of war!

    Yes, making a part on conventional machines is cheaper. But where are these machines in Afghanistan, Iraq, Ukraine ??? And to bring a spare part from across the ocean costs money and most importantly TIME. Now DARPA is already testing this technology in real conditions on Asian bases.

    Imagine a situation that in Chechnya we could print any part for a tank or armored personnel carrier in 2 hours in remrot. What is more important to the commander that this part is 100 times more expensive or that the tank can go into battle again ?! And all you need to have in the company comp + ZDprinter + bagPowder = ANY spare part.

    Therefore, all such articles about printing weapons are the manufacturer's request "buy my printer in the repair shop, because it can print spare parts"

    Conventional powder metallurgy, and, which is characteristic, by the end of the 80s, it was only developed in the USSR to industrial use. If it were not for the subsequent "events", everything would have been sintering here for a long time ...
