Academic tyrant: I have become a prodigy since I was able to pursue my academic career with peace of

"who is he?"

"You don’t even know this, it’s Chen Fan"

"Is it the Chen Fan who invented 5G, holographic technology, and the panda robot?"

"That's right, it's that Chen Fan!"

"incredible."

There are three meals and one soup on the table. It can be said that they are all delicious and delicious.

Leader No. 3 said,"Would you like to order a few more dishes?

Chen Fan said,"No need.""

Leader No. 3 came from a young age. The last time he ordered a lot of food, the two of them didn't finish it. They felt a little distressed.

This time, they asked Chen Fan for his opinion and ordered something he liked.

The two of them ate while eating. chat

"Your Fan technology is being built very quickly."Leader No. 3 said with a smile.

Chen Fan was a little helpless,"It's not because of the help of leaders and the government that the efficiency is so high."

Money leads the way, and the military and government cooperate.

How can it be inefficient if this is the case?

It is also in line with his expectations and calculations.

Leader No. 3 smiled and said,"It's good to know. The country has made a lot of efforts behind this matter. You Remember. Chen

Fan smiled and said,"This is natural.""

Leader No. 3 said again,"What have I been studying during this period? I haven't seen you walking around. If you have nothing to do, you can come to my place. I will give you a pass."

Both the military and the government are interested in Chen Fan. A good scientific researcher is a rare talent for the whole of China.

No, many people have become greedy and cannot get close to Chen Fan. They have begun to assassinate him. Chen Fan said

,"I have been studying anti-gravity for a long time. But there was little progress. After failing for so many days in a row, my mind is a little confused, so I came out for some fresh air today."

Anti-gravity is really the one that he has failed the most and for the longest time since he started research work. He still can't figure it out.

It's a difficult problem among problems.

Leader No. 3 was a little surprised when he heard Chen Fan's words. He didn't expect it. Chen Fan really plunged into the research of anti-gravity.

Although he was not a scientific researcher, even a layman like him knew that anti-gravity was impossible at least in the past two or three hundred years. It's impossible within two to three hundred years, and whoever develops it will definitely attract the attention of the world. Why

?

Because it will subvert the entire world's research, such as anti-gravity cars and anti-gravity houses.

, cars that can go to the sky, houses that can go to the sky, spaceships that can go to the universe, etc. will come out one after another.

That is the dividing line between modern society and future society.

Therefore, it is normal for Chen Fan to fail!

"When it comes to scientific research, take your time, don't rush."Leader No. 3 smiled and said,"Maybe you can set a small goal for yourself first."

"Small goals?"Chen Fan raised his eyebrows,"What about?"

"For example, invent a 3D printer or something."Leader No. 3 said

"Isn’t it already there?"Chen Fan said.

Simply put, 3D printing is a type of rapid prototyping technology, also known as additive manufacturing. It is based on digital model files and uses adhesive materials such as powdered metal or plastic to create products step by step. A technology that constructs objects through layer printing.

3D printing is usually implemented using digital technology material printers. It is often used to create models in the fields of mold manufacturing and industrial design , and is now gradually used in the direct manufacturing of some products.

There are parts printed using this technology, so Chen Fan asked this question.

"I don't understand, just say it casually."Leader No. 3 said with a smile,"However, it seems that 3D printing is not very mature now. As far as

I know, this thing is still widely used, such as in aerospace, geographic information systems, especially in guns. branch field. Chen

Fan nodded,"That's right. The current 3D printing technology cannot be applied to mass production. Although some people advocate that 3D printing is the third industrial revolution, this statement is a gimmick. Due to material limitations, there are very few other products that can be produced."

"So, if you want to make this gimmick real, you need to find a new type of material.

Leader No. 3 smiled and said,"New materials?" What kind of new material?"

Chen Fan said,"It can have strong ductility, hardness, low density and light weight.

Leader No. 3 heard this and said with a smile,"Reinvention?""

Chen Fan shook his head,"Not necessarily. It may be some kind of substance that already exists in the world, but it has not been discovered by humans yet."

After eating, Chen Fan said goodbye and left, returning to the research institute.

The small goal proposed by leader No. 3 inspired him.

3D printing technology.

There are currently four main obstacles to 3D printing technology.

The first is the limitation of materials..

Although high-end industrial printing can achieve printing on plastics, certain metals or ceramics, there is still no way to achieve printing materials at a level acceptable to the public. For ordinary paper printing, three-dimensional printing can do this, but other materials are. They are relatively expensive and scarce, and the printer has not yet reached a mature level and cannot support a variety of materials that are encountered in daily life.

Although it has made certain achievements in multi-material printing such as paper and sculptures. Progress, but unless these advances are mature and effective , materials will still be a major obstacle to 3D printing.

The second point is the limitation of the machine. 3D printing technology has achieved a certain level. , almost any static shape can be printed, but those moving objects and their clarity are difficult to achieve.

This difficulty may be solvable for manufacturers, but 3D printing technology wants to enter ordinary households. , everyone can print whatever they want, then the limitations of the machine must be solved.

The third point is concerns about intellectual property rights. In the past few decades, the music, film and television industries have been concerned about intellectual property rights. Concern becomes more and more.

3D printing technology will also involve this issue, because many things in reality will be more widely distributed. People can copy anything at will, and there is no limit to how to make 3D printing. Regulations are used to protect intellectual property rights, which is also one of the problems we face, otherwise there will be proliferation. The last point is the moral challenge. Morality is the bottom line. It is difficult to define what kind of things will violate moral laws.

Printing biological organs and living tissues will encounter great ethical challenges in the near future, as well as guns etc.

Of course, these four points are not within the scope of Chen Fan's consideration. Further improve the current 3D printing technology. It is indeed a black technology that is currently accessible to humans.
