China began to print military aircraft on the 3D printer

The Chinese showed industrial designs of the power parts of a glider fighter, made of titanium, using laser 3D-print.

The presented detail is the carrier part of the airframe and serves as a holder for jet engines of a modern fifth-generation fighter. The use of this technology allows you to make a monolithic detail, which reduces weight, cost and increases strength and accuracy.

In addition, production of parts for chassis, flaps, and insulation panels has already been launched.

Already, technologies allow the manufacture of modern weapons at home, so a pistol printed on a home 3D printer from nails and other improvised means, successfully fired nine shots. Creating a deadly "toys" cost its inventor just 25 dollars. Soon, a Texas student plans to lay out the drawings for a homemade gun on the Internet.

No sooner had a University of Texas student printed a pistol on his 3D home printer as his compatriot produced plastic bullets in a similar way. Their inventor test shot on video.

A video appeared on the Internet that clearly shows the destructive effect of bullets printed on a three-dimensional printer. The author of the video shows the audience three bullets of different sizes and shapes. Then his partner consistently shoots them with a 509 Mossberg rifle at various targets. Plastic “pills” equipped with lead shot from a distance of a couple of hundred meters carry the board for darts to feathers, leaving holes even on the iron canister to which the target was leaned.

Now the process of copying and developing new military equipment by Chinese manufacturers will become even easier and faster. It is enough to disassemble a foreign sample. With the help of 3D scanner, to make digital models of complex parts, and then without implementing complex technology of their production in the usual way, just print the parts on an industrial 3D printer.

Defense Distributed is a network organization working under the open source ideology and developing firearms (the so-called wiki weapons), the components of which can be printed on a 3D printer.
The first practical results were obtained by December 2012, when the test tests of the developed samples began. Currently, standard-capacity stores for the AR-15 rifle and AK-47 assault rifle, a silencer, a part of the receiver (pistol grip, trigger guard, magazine receiver) of the AR-15 series assault rifles and a holder (but not a clip and not a magazine for charging) have been developed cartridges must be removed from the holder) of three cartridges of 12 caliber smoothbore guns, and all modifications can be used in real weapons instead of standard steel parts. Such an approach in the future should make it possible to sharply reduce the weight and cost of a unit of firearms.
I.Materialize is engaged in the printing of three-dimensional objects from titanium using Direct Metal Laser Sintering (DMLS) laser sintering technology. A three-dimensional printer applies titanium powder layer by layer, and a powerful laser beam following the head of a three-dimensional printer sinteres this powder into a monolithic metal. Sintering is a fairly common process of converting a powder into a solid material using high temperature, but without melting the material itself.
selective laser sintering (Eng. selective laser sintering, SLS) (also Eng. Direct metal laser sintering - DMLS) - the object is formed from fusible powder material (plastic, metal) by melting it under the influence of laser radiation. Powdered material is applied to the platform with a thin uniform layer (usually a special leveling roller), after which the laser radiation forms the current layer of the object being developed on the surface. Then the platform is lowered to the thickness of one layer and powder material is again applied to it. This technology does not need supporting structures of the "hanging in the air" elements of the developed object, due to the filling of voids with powder. To reduce the energy needed for sintering, the temperature of the working chamber is usually maintained at a level just below the melting point of the working material, and to prevent oxidation, the process takes place in an oxygen-free environment.

This is all powder metallurgy, known since the seventies. It does not provide strength characteristics for parts with dynamic loads, no matter what material the metal powder is made of. Example - All Western traumatics are pressed using powder metallurgy (due to legal restrictions), ensuring that if the owner wants to shoot with a standard live cartridge, then at least he risks being crippled.
And in aviation, this is generally some kind of nonsense - parts of load-bearing structures made of powder.

The Chinese are well done, but we have to put a bolt on the concept of copyright to invention. IMHO.

Everyone always laid down, intelligence worked well.
It’s just that the Chinese, by virtue of a strong civilizational backwardness, stole whole concepts, including the appearance of products, and we and Americans - complex technical solutions, individual units. Therefore, it is so noticeable for the Chinese, but not for us.

It is not a matter of patents. China is not shy about copying, unlike us. Where are spent (read plundered) millions of money for the invention of what was invented about 20 years ago. With our secrecy, one KB can spend money and time on the invention of what another KB has already done and handed over to the archive for no need.

Let there be copyright, but not more than 5 years. Everything is clear R&D needs to be bought, and if two companies are simultaneously conducting research, what should I do?

Bioprinters - 3D printing of the future structure of an object (organ for transplantation) is done by stem cells. Further division, growth and cell modifications provides the final formation of the object.

Currently, regenerative biologists have managed to print the heart of a rat, which was successfully implanted in an experimental animal. Scientists say that the ability to print complex human organs (such as the kidneys and liver) is just a matter of time. According to experts, a new breakthrough in regenerative medicine can be made in the next three to five years.

However, biologists argue that their invention can benefit people today. For example, on the latest bio-printer, you can print pieces of skin, which will greatly facilitate the lives of people affected by burns. Doctors hope that huge transplant lines will soon become history.

Therefore, only We make titanium power structures for Airbus and Boeing ....

But the printer is already a reality, powder metallurgy is not even today - yesterday, so if you put your head and hands in working out a specific technology for manufacturing parts from semi-finished products, printed "on a printer, then the production prospects are quite imaginable in mechanical engineering.

It smells like deso, because such technologies have appeared recently.
And it is unlikely to build such a plant in such a time frame, much less produce such parts in batches.

[jagdpanzer]

the part may be printed but its strength is sufficient for a combat fighter

[komel]

They will not print the entire object, it is possible to print individual parts now. Mass character and high accuracy of parts makes it possible to apply this technology for industrial purposes. Some parts in their physicochemical properties may have properties superior to conventional ones due to their multilayer nature and low weight. Recently, the number of materials used for three-dimensional printing has been steadily increasing.

[komel]

The plane was shot down near the village of Budanovtsy during the NATO military operation against Yugoslavia practically did not contain metal. You won’t give up on metal like that.

The advantages of composite materials.
The main advantage of KM is that the material and structure are created simultaneously. An exception are prepregs, which are semi-finished products for the manufacture of structures. It is worth mentioning right away that CMs are created to fulfill these tasks, therefore, they cannot contain all the possible advantages, but, when designing a new composite, the engineer is free to set characteristics that are significantly superior to the characteristics of traditional materials for this purpose in this mechanism, but inferior to them in any other aspects. This means that CM cannot be better than the traditional material in everything, that is, for each product the engineer carries out all the necessary calculations and only then selects the optimum between the materials for production.

high specific strength (strength 3500 MPa)
high rigidity (elastic modulus 130 ... 140 - 240 GPa)
low wear resistance
high fatigue strength
it is possible to make dimensionally stable constructions from KM
ease

Moreover, different classes of composites may have one or more advantages. Some benefits cannot be achieved at the same time.

What the fuck ... sensation?
Some questions.
If a part is subjected to hardening during tempering or, on the contrary, tempering, the crystal lattice of the material changes. It is exposed to electrochemical effects, moreover, in layers and layers. A lot of high-precision casting technologies and all this is easy to waste ???
Despite the fact that China is doing this, I would understand if the Americans started to produce it.

[Andrew 447]

I agree to all 100%. The Chinese do not abolish the laws of physics and chemistry, and the crystal lattice structure also. Metal technology and sopromat do not tolerate amateurs. 3d is relevant for polymers and composites, for metal products working under load is nothing more than a bluff.

Perhaps such an apparatus would produce metal parts if the atomization unit would be atom. But breaking the bonds between the atoms and then connecting them will not be enough energy of the nuclear power plant.
In aviation metal processing, this is a technology for the distant future.

[mountain]

Raw, printer, more technology, so that they would be like that from the office, apply immediately. Doctors and stories and tales. But for now, what will happen next, time will tell. Time and technology do not stand still.

[wanderer_032]

Products made using 3D printing technology are not yet perfect, have a low margin of safety and a resource of work (compared to traditional technologies). As long as this is a semi-experimental technology and you do not need to hang pink drooling and draw pink dreams.
If the PRC collects its warplanes from such units, then this is simply idiocy.
And most likely nonsense.

[zollstab]

China has huge potential and not believing in it is like burying your head in the sand ...

[Andrew 447]

The potential of China is huge in the production of consumer goods. High-tech products of Chinese development are absent as a class. They copy well, upgrade the copied product, but somehow it’s very incompetent and sometimes absurd. I have been working with China for many years and it is striking if they don’t have a culture they try to improve the use of a product completely mediocre. For example, if they are very good at badminton, then they do not allow silly and expensive oddities in the production of rackets.

People, this is just the beginning. Vacation and so on. CAST parts are exposed, in which internal stresses are formed due to uneven cooling. When sintering the thinnest layers of powder metal, such stresses will not occur. So the proper strength is a matter of time. You have to think with your head when we sell advanced samples! It gets to the point that we show the layout as an idea, and the Chinese and other "friends" will instantly make a working sample. Their R&D costs are just a few 3D photos from the exhibition ...

And Asgard is right .

Faced a little with titanium. This is such a metal, when hot processing a couple of kilograms of which it is nice to have firefighters with carbon dioxide fire extinguishers nearby. And with 3D printing, i.e. during laser processing, not just firefighters, but a tank with nitrogen or carbon dioxide. Burning titanium burns through ceramics, bricks in a simple way. And up to half a meter, if titanium 10 kilo. Because he is dear, although in nature it is immeasurable.

Bullshit is . At the level of ancient Chinese tables of logarithms. Where even errors coincide with errors in Bradis tables.
