Hand rubbing nuclear fusion live in the wilderness

Chapter 471 The Key to 3D Printing Materials

In the simulation space, Han Yuan stood on the top floor of the reactor building, leaning on the railing and looking at the X-1 industrial robot running around below.

The other buildings in the nuclear fusion reactor park were completed more than a month ago, but the reactor building is still only about two-thirds of the project completed.

It is estimated that the rest of the project will take at least one month to complete.

After the main project is completed, the components of the controllable nuclear fusion reactor can be manufactured based on the actual survey drawings of the entire plant.

Compared with the progress of other buildings that have already begun to move various equipment inside, the construction progress of the reactor plant is simply too slow.

But Won can't help it. So far, the number of X-1 industrial robots he can use is still only [-] units. After the exchanged materials are exhausted, there are no new additions at all.

And it is impossible for him to arrange for these three hundred industrial robots to build the reactor building.

The maintenance of various areas in the base, the maintenance of various equipment, the construction of 3D printing factories, and the construction of infrared space telescopes all need industrial robots to handle.

Therefore, there are only about 150 robots actually applied to the entire nuclear fusion industrial park.

Moreover, at the beginning, not all of the 150 industrial robots were repairing the reactor building. They were not assembled until the construction of other parks was completed a month ago.

Otherwise, the progress will be even slower than what you see now.

But the good news is that the artificial intelligence core in the central computer sent a message a few days ago, indicating that the 3D printing factory has completed the construction as a whole and is now installing 3D printing equipment.

After all the installation is completed, the X-1 industrial robots can be produced continuously.

At this time, there will be no shortage of industrial robots available to him.

After staying on the top floor of the reactor building for a while, and following the audience in the live broadcast room, after going around the various floors, Han Yuan rode on his little electric donkey and came to the freshly baked large-scale 3D printing factory.

Compared with the reactor building, a large-scale 3D printing factory is much lower, but the floor area is not much smaller. Although the floor area does not reach [-] square meters, it is still nearly [-] square meters.

Moreover, compared with the square nuclear fusion reaction park, the layout of the 3D printing factory is rectangular, so from the front, the occupied area appears larger.

The reason why the 3D printing factory is designed like this is to consider the work efficiency.

For a long factory, dozens or even hundreds of doors can be opened on both sides of the factory.

Then plan the use of each area. For example, the first area is used to specialize in the production of X-1 industrial robot spare parts, the second area is used to print physical equipment, and the third area is used to produce industrial equipment. and many more.

Each area can correspond to a factory gate. In this way, it is enough to directly arrange the corresponding area to produce the parts of the equipment that needs to be produced.

It is also more convenient to transport various raw materials and finished products.

When you walk into the 3D printing factory, what you see is a bright and spacious interior space. Countless incandescent lamps are on even in the daytime, like shadowless lamps, illuminating every corner of the factory building.

Then came the X-1 industrial robot that came and went to carry large printing equipment in the factory.

As far as I can see, the types of printing equipment that have been installed are the same, and the appearance is also the same. They are exactly the same, and they look like lithography machines.

However, unlike photolithography machines, these printing devices are not installed in an alloy frame, but are wrapped in high-strength transparent tempered glass.

The various parts inside can be seen clearly.

The audience in the live broadcast room were very curious and interested in this design, and discussed it one after another.

[Why is this 3D printing factory a little different from what I imagined?At first I thought it was a robot with countless robotic arms carrying material pipelines, just like in the movie. 】

[These are printing devices, right?It doesn't look too big, can the robot be printed out completely? 】

[Using glass as the casing of the printing device, the anchor, you are also a genius, but you can see it clearly. 】

[I remember that there seems to be a house in our country that is entirely manufactured using 3D printing technology, including wall bricks and tiles, which are all printed at one time. 】

[The anchor should only be able to print some spare parts. 】

[I think it should be assembled after printing the spare parts. The overall printing is not realistic. You can’t handle the battery alone, not to mention the magnetic bearing. 】

[I just went to Baidu to check the one mentioned above. This boss is from the countryside of Beihu, with only a junior high school diploma. He started as a building materials business. He started from the control system and material supply system step by step, and finally achieved a printer that can print high-rise buildings. Really awesome. 】

[3D printing houses, it seems that learning civil engineering is really a dead end. In the future, building a house will not require dusting, so let’s get into the computer as soon as possible. 】

[Hahahaha, my big computer really needs talents!Come lose your hair with us! 】

[When we were in college, our teacher of metal materials told us that as long as the material problem breaks through and metal is used in 3D printing, there is no need for machine tools. 3D printers can directly print out materials without the loss of lathe cutting. 】

[Indeed, it is unnecessary, as long as the material problem can be solved, 3D printing is much more convenient than CNC machine tools. 】

The audience in the live broadcast room stared at the various equipment in the 3D printing factory and discussed continuously. Even experts from various countries were thinking.

Needless to say the anchor, even in the real world, 3D printing technology has always been a key direction of research in various countries.

For example, one of the ultimate research directions of powder metallurgy is metal 3D printing.

However, there are many difficulties in 3D printing technology for metals such as steel, such as its high melting point, difficulty in ensuring the performance and strength of equipment at high temperatures, and difficulty in heat treatment during printing.

It is foreseeable that for a long period of time, except for low melting point metals such as aluminum, 3D printing cannot be applied to the metallurgical industry.

But if the material problem can be solved, it is certain that 3D printing factories will replace various CNC equipment to produce spare parts and various tools.

Because compared with CNC machining, 3D printing has many advantages.

Its advantages include saving materials, fast finished products, precise and diverse configurations, no need for machining, product customization, etc.

In comparison, CNC machining has no other advantages other than ultra-high precision, and it can even be said to be crushed by a large level in terms of efficiency.

And even in terms of accuracy, after breakthroughs in materials, ranging tools, and models, it is not a big advantage.

At least at the micron level, 3D printing can be exactly the same as the products processed by CNC equipment, without any gap.

The only problem when 3D printing the material is how to solve it.

This point, the anchor in front of him has not shown it before.

If he can demonstrate this and make it perfect, only the top-level CNC equipment may survive in the future, and the low-end CNC equipment will be replaced by 3D printing technology.

In the 3D printing factory, Han Yuan smiled as he watched the barrage discussed in the live broadcast room.

"Everyone is familiar with 3D printing technology. Through additive manufacturing, this technology can print objects of any shape you can think of."

"The only downside is how it's going to be materialized."

While talking, Won walked forward.

In this large-scale 3D printing factory, the raw materials printed in each area are different.

Here, the box-packed printing equipment similar to the lithography machine is used to print materials such as plastics, plastics, and metal wires that do not need to go through high-temperature plasticity steps. They are suitable for box-packed printers.

The printing equipment used for the X-1 industrial robot is not so simple.

Because the parts used on the robot need to have ultra-high-strength metals, so as to support its activities and work.

After all, if you use ordinary materials to print, the manufactured things are just waste, and they may fall apart before taking two steps, let alone moving things.

Soon, the Korean won came to the central part of the 3D printing factory.

Here, a large area is completely isolated from the surrounding area, sealed as a whole, completely sealed by concrete and various plastic materials, and does not communicate with other areas of the factory building.

After passing the verification, Won entered this rather eye-catching isolation room.

Unlike other areas of the 3D printing factory where handling equipment is being assembled, this one is already in operation.

The structure inside looks like a small assembly line processing factory, but this processing factory is relatively high-tech.

There are assembly line-like production lines on the left and right sides, and the entire production line is wrapped in high-strength tempered glass, leaving only a passage less than two meters long.

Han Yuan tapped on the tempered glass and said, "This is the core area of ​​the entire 3D printing factory."

"What's being produced inside is an additive for 3D printing materials."

As he said that, he came to the end of the assembly line and found another box, and there was an X-1 industrial robot next to the box.

Look at the action, it is to transfer this box.

"Luckily, there just happened to be a box of additives that hadn't had time to be transferred into the warehouse."

As he spoke, he called to stop the robot that was about to carry the plastic material, and opened the box made of special resin, revealing the silver-gray powder inside with a faint metallic luster.

Leaning down, Han Yuan grabbed a handful of silver-gray powder, showed it under the camera, and said: "This is a special alloy material, the full name is 'trialuminum titanium holmium-diyttrium-ammonia carboxy complex material'."

After introducing the name of this material, he did not mention its specific use, but wanted to talk about the defects of 3D printing technology.

"In 3D printing technology, everyone knows the most difficult problem is the material."

"Materials limit the development of 3D printing technology."

"Especially in the aspect of metal material printing, it is limited by the performance of the metal material itself, resulting in the physical and chemical properties of the printed parts such as dimensional accuracy, shape accuracy, surface roughness, strength, stiffness, and fatigue resistance. It cannot meet the actual use requirements of the project."

"In short, the printed parts cannot be used as practical functional parts, but can only be used as prototypes."

"The reason for this problem is that 3D printing mainly uses powder materials or fluid materials to build parts."

"For example, metal powder, which uses the additive manufacturing process of "layer-by-layer manufacturing, layer-by-layer superposition" through a 3D printer to manufacture metal parts."

"But there will be a problem with this kind of manufacturing, that is, no matter how tight the combination between each layer of metal powder is, it cannot be compared with the parts cast by traditional molds, nor can it be compared with the parts made by powder metallurgy. parts compared."

"Because it lacks the stamping and sintering steps necessary for powder metallurgy."

"The microstructure and structure of a part determine the performance of the part."

"The densities of printed materials produced by lamination cannot match that of cast and sintered alloys."

"That's the main reason why 3D printing technology can't really be applied to metal parts."

While speaking, Han Yuan pinched the silver-gray material on his hand, and part of the powder glowing with submetallic light fell back into the box, while the other part stuck to his hand like a gangrene, shining with silver light.

"This material named 'trialuminum titanium holmium-diyttrium-ammonia carboxyl complex material' was manufactured in the last month of the last live broadcast."

"Its main function is to be doped in the printing material. At a temperature of about [-] degrees, it can quickly melt into a liquid and react with most metal printing materials to form a chelate."

"This kind of chelate is a complex with a ring structure, which forms a chelate ring with the same metal ion through two or more ligands."

"It dissociates the aminocarboxyl ions on the 'trialuminum titanium holmium-diyttrium-ammoniacarboxyl complex material' through the reaction of the ligand group, and then coordinates with the metal ions in the metal printing material, thereby stabilizing the metal printing material."

"In this way, the physical strength and chemical properties of printed parts can be greatly enhanced."

"."

Before Han Won finished speaking, the audience in the live broadcast room was already dizzy.

[Scary, so scary, I can't understand again. 】

[A series of various nouns made me dizzy. 】

[Ma Dan, is there anyone who is big and knowledgeable to come out and explain briefly! ! ! ! 】

[Stop shouting, I don’t understand how big the bird is. 】

[It is estimated that there is no knowledgeable person, because 3D printing technology is still a cutting-edge technology on our side, mainly because the material problem cannot be solved. 】

[I know about chelates. I study environmental protection. This thing is used a lot in sewage plants. It can be used to absorb heavy polluting metal ions in sewage, and the effect is very good. 】

[As for alloys, I understand a little bit. To put it simply, it is to enhance the hardness, toughness, and other physical strength of metal printing materials by doping this three-aluminum-titanium compound material. 】

[In other words, this thing is actually glue? 】
