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

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».

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.

[RusSever]

I completely agree with you. To make a barrel with rifling, a shutter mechanism, a trigger mechanism - all this was printed ??? I'm very doubtful. This is quackery and the euphoria of quackery.

[Silumin]

To make a barrel with rifling, a shutter mechanism, a trigger mechanism - all this was printed ???

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 ".

[Rus2012]

Quote: Silumin

And why not?

And if you carefully watch the video, you can see that without additional final processing fur in the form of grinding and polishing - it does not work! This is the time.

The second one. Any hardening operation, in the form of hardening, HDTV, nitriding, anodizing ... and a surface class higher than 20micron, also does not work.

Third. There were and are technological processes such as "plasma spraying", "vacuum spraying", Paton's "welding (and casting, by the way, too) under a layer of flux", EEO-electrical discharge machining, which can also be pulled under "3D printing".
And yell all over the world and show tricks ...

By the way, almost all of the above technical methods were proposed and mastered in the Soviet Union ...

[Silumin]

And yell all over the world and show tricks ...

So this is what you need to do, yell at advertisements, beat out grants for the development of equipment, etc.

But we have a nanochubais.

[Aleksey_K]

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.

[Vadim237]

Ten years later, airframes will print and process and temper and release - all on one machine.

[Saratoga833]

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!

[user]

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? 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.

[Silumin]

otherwise the "pukalki" are promoting their own, which are 10 times more expensive than a simple, very high-quality pistol.

Hah, it’s expensive now, but when the technology is developed and mass, there will be cheap weapons and other metal products, due to savings.

For three years now, we have been manufacturing titanium alloys, blades for aircraft turbines, and the like.

"scanning" technologies that apply / process / modify the material using a "point machining center" working with THIN LAYERS and at the same time with HIGH DETAILS RESOLUTION CANNOT BE CHEAP ...
- you understand that this "processing head" - it must "go around" the ENTIRE SURFACE OF EACH PRODUCT MANY TIMES: line-by-line.
And this is DOOOOLGO. Always long ... because the material has a PHYSICAL ORGANIZATION in terms of processing / spraying / modification speed ...
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.

precision mechanics, precision actuators - all this gradually wears out, loses accuracy, requires periodic adjustment, calibration, cleaning, lubrication, etc., etc.

This is all decided by the sophistication of the technology, the quality of training of specialists (one specialist can easily service about 10 machines), and the cost of mass production.

- Dear, you are simply not in the subject ...
8-)
- You can believe (or check) that today "everyone has a phone and a computer" - solely for the reason that they DO NOT use ultra-slow and not (!) Reliable "scanning technologies" (like a printer head) ...
.
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!

..."
.
8-))
.
- my gaze is not directed forward, and not backward ...
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).
8-))
.
Let it take 0.01 seconds to "create" each point at the printer head (in reality, it should be at least TEN times longer - but let ... I "don't mind" ... 8-)
.
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 ...
.
- Ie just 108 days - and you can pick up your "pad" on the handle, made with an accuracy of 20 microns - agree ?!
8-))
.
And here I am not even discussing such a burning issue as the RESOURCE of the "print head" (MTBF). Well, like - will the "print head" withstand the "production" of 937 million (!) "Elementary dots" without a radical deterioration of the PRINT ACCURACY? And will it withstand at all? ...
.
- And this, mind you, is by no means the ENTIRE "revolver" - but only ONE (!) COVER (for example, LEFT) on its handle.
“And the whole revolver?”
- All? ... Well, if "ALL" - then come in, YEAR, some way, after THREE-FOUR ...
8-))
.
.
PySy.
Do you know how the ENGINEER differs from Charlatan?
- because at first glance - they are BOTH engaged in Predictions!
8-)
- the difference is that the engineer MUST - NUMBER (at least with accuracy TO ORDER) to ESTIMATE his prediction. And to explain - WHY he got such a result ...

Weapons is the most technologically advanced and sought-after industry in the US market. Most of all technologies came to us from the defense industry. Computers, airplanes, metallurgy (forged good swords, those who were power were not bothering then), post-traumatic medicine and even vaccinations, all this and much, much, much more, has military roots. It’s just that the military industry is technological, coupled with huge investments, at first the technology is gaining strength in the military industry, and only then, it is being adapted for the civilian market.
And besides, in a citizen, this technology also runs in, out in the Netherlands (or Denmark, I don’t remember exactly, to be honest), they built a house printed on a 3D printer, right now it’s standing, they are testing it and, in general, checking and studying it in every possible way.

On the moon, spare parts for riveting technology

[Saratoga833]

Humanity on this path is only at the very beginning of the journey! Over time, you will have both productivity and low cost!

[kirqiz ssr]

Explain to me that the Russian was not bombarded with powder and the result was a pistol. How it will shoot is just a piece of iron without a hole in the barrel.

[_my opinion]

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 ...

[gridasov]

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. Then everything connects. Only this is done by a program given by the computer and issued to the carriage, which moves the tool (this cutter, drill, etc.) in three axes.

[_my opinion]

... the technology you described is a principle when everything that is unnecessary is deleted, and everything you need is added to the 3D printer. This is a fundamental difference ... if in other technologies the material is removed, then in this technology the material is added.

[gridasov]

Adding is gluing, welding, finally riveting, nailing, etc. Therefore, 3D technology is the principle of manufacturing with one tool in three axes of the dimension of the part. If you justify your reasoning, we will be grateful.

[Silumin]

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.

[Silumin]

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.

[gridasov]

Not the guys! I thought you were adequate, and I don’t get stuck in such arguments. Sculpt children's toys from powders. And I'm talking about a set of properties that allows the pool to fly, rather than tear the trunk. This requires the strength properties of materials. Etc. Tell tales to students.

[Silumin]

Not the guys! I thought you were adequate, and I don’t get stuck in such arguments

We have explained how the 3D printer works.

Children's toys sculpt from powders

Jet blades are made by sintering powders of titanium alloys.

And I'm talking about a set of properties that allows the pool to fly, rather than tear the trunk. This requires the strength properties of materials

Many billets obtained by sintering powders are not inferior in strength to cast billets.

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.

[Aleksey_K]

And so they do. The barrel is checked, the metal is welded on and cut again. ... "Disassembled the old AK, assembled the AK - received a new AK!"

[Silumin]

No, he probably meant: they dismantled the ak, assembled the ak, trimmed with planks, got a new model of ak.

And what nano-developments can h (U) ubais boast ??? - the next cut of money?

[Vadim237]

Of course, this is his job to cleanse the state.

[SmolNik]

the science. Aries pharmacists together with the colleagues of the analytic device invented a new gas detector STG-1. when an accident occurs, he turns on the color music, a funeral march sounds and starts generating empty boxes for the patients.

[mivmim]

Yes, our Makar is better.

[Aleksey_K]

Our Makar is not the best system and it is high time to abandon it, at least because of 8 cartridges. Now there are pistols with stores of more than 20 cartridges.

[Silumin]

The system is ideal for its cartridge, as it is well-suited for concealed and everyday wear, and the weak ammunition is ideal for both the police and civilians.

But the store’s capacity is too small.

[Denis fj]

PM was created based on the experience of the Second World War. PM acts in the compact class.
The gun in war is not the main weapon, and therefore it is necessary that the gun weigh less, get faster.

[Major_Vortex]

Something tells me that the technology is very expensive and will never completely replace the current metalworking. The "machine" itself, I think, costs at least several hundred thousand (if not millions) dollars. "Powders" for baking are also expensive.

He reasoned logically. Do not be offended if you hit anyone.

[Silumin]

Of course, since it is experimental.

[Major_Vortex]

Of course, since it is experimental.

I'm not even talking about that. Study the question with what precision modern CNC machines are used to process metal, on which many critical and high-precision parts used in weapon assemblies are made. And after that, figure out what size the "granule" of metal for a 3D printer should be, with what tolerances in size and shape, and with what accuracy should this "printer" sinter all these "granules" with each other?

Have you figured it out? Now estimate the total number of granules in the part, time and energy consumption for their sintering? And the most interesting is the machine that produces these granules with the right quality, accuracy and in the required quantities ??? ...

It was smooth on paper, but forgot about the ravines

[Silumin]

Study the question of how accurately metal is machined by modern CNC machines, on which many critical and high-precision parts used in weapon assemblies are made.

At the same time, a huge amount of metal is spent, part of which will go to waste.

... And after that, figure out what size the metal "granule" should be for a 3D printer

It is not granules that are sintered, but powders; the particle size in the powders is 1 to 100 microns.

And the most interesting thing is the machine that produces these granules with the right quality, accuracy and in the required quantities

You probably don’t know about powder metallurgy.
Powder production:
Mechanical grinding of metals is carried out in vortex, vibration and ball mills.
Another, more advanced method for producing powders is the spraying of liquid metals: its advantages are the ability to effectively clean the melt from many impurities, high productivity and efficiency of the process. R
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.
Hydrometallurgical methods for the restoration of solutions of the compounds of these metals with hydrogen are used.
To obtain copper powders, electrolysis of aqueous solutions is most often used.
There are other, less common methods for preparing powders of various metals, for example, electrolysis of melts and thermal dissociation of volatile compounds (carbonyl method).

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.

[Silumin]

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

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

The 3D printer will not give such tolerances and does not meet such high requirements. This will be especially evident in mass production, and not in the laboratory, in the manufacture of piece parts at the price of an airplane.

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.

[Silumin]

Definitely plus

[Saratoga833]

Technology does not stand still! With such concepts, we would still run with stone axes!

[MAXUZZZ]

12 kilobaxes for engraving-normal move, drug cartels with gilded trunks nervously smoke aside

[Inferno]

Brains would have printed to their own State Department!

[midshipman]

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.

[Evilcat]

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.

[SmileSimple]

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"

[Massik]

Do auto parts fly too often? Two repair kits last for 3 years almost every day, 8000 shots still need to be done to start the machine repair.

Already in March of 2015, Russian scientists plan that with the help of 3D technology they will be able to print a living and functioning organ ...
Such is the difference between the mentality of the Russian and the Americans.

USA - we printedwhether pistol

yeah nobody in the world can make artificial blood

What about Perftoran?

[Megatron]

Five years later, the class printed its own weapon, and go!

[Victor-M]

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.

A marketing move to lure a customer. These are the Americans.

[Plato111]

12000 bucks? !!!
Down and Out trouble started.
In a couple of years, manufacturing costs will fall by half.
Then, in general, it will become comparable to the traditional method of phrasing

[SveTok]

If this is true, then the economy will receive a new impetus to development due to the tremendous saving of resources.

[Wolka]

the idea is good, it’s a pity if it still turns out to be a one-time consumer goods, as well as an interesting thing, I would like to know its resource, the trunk is probably forged from steel anyway ...

[Pazifist87]

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 ...

Now we look and envy, but we have "nanotechnology" and "innovation", ugh damn it ...
