"Xiao Li, what do you want?"

Gu Ping and Li Yifan talked about her imagination in the medical field, but she didn't expect that the 3D printing jishu she inadvertently mentioned made Li Yifan lose his mind all of a sudden, and suddenly remembered a lot of ins and outs about this jishu, and there are benefits.

Li Yifan was distracted, but he walked for more than ten minutes, thinking too much, at the beginning, Gu Ping didn't care, but then when she saw that Li Yifan hadn't spoken for more than ten minutes in a row, and there was still a thoughtful expression on her face, she felt strange, so she couldn't help but reach out and push Li Yifan, and asked out loud.

"Oh...... Forehead...... I'm sorry, Sister Ping, just now I was also attracted by the 3D printing jishu you mentioned. When I was at Kyoto Normal University, I once went to give a lecture by a teacher in the physics department, and I talked about this jishu, and it was very interesting, and it was very interesting to listen to at the time. But afterwards, I didn't take it to heart, but now when I hear you talk about this jishu, which has begun to be initially applied in the United States, and even some medical experts have begun to try to use this jishu to make kidneys, I feel very surprised, and I think about it again and again...... Hehe, I'm a little distracted, don't be surprised......"

"Hey! What should I do?,You boys.,Especially those from science and engineering.,No wonder people say you're jishu crazy.,If you mention a certain jishu.,You'll think about it.,Forget it.,I'm not used to it.。 ”

Gu Ping also understood when she heard it, she had more contact with such people who like science, and knew that they all had such problems. Especially when talking and chatting together. If you want to mention a certain item they are interested in.

Either they are breaking the casserole and asking to the end. Either she will be distracted by crankiness on the spot, and she has a lot of yujian in this situation, so it's not strange to see it.

"By the way, Sister Ping's 3D printing jishu is now developing very well in the United States? Those doctors have already started to use this jishu to help people replicate kidneys? ”

Li Yifan remembers very well that the Americans really made a breakthrough. When it came to this field, it should have been ten years later, and it was the breakthrough of Haval's medical team.

However, just now Gu Ping said that the Americans have begun to have this idea, and he also wants to know where the Americans are now.

As soon as she heard Li Yifan ask like this, Gu Ping's face was also a little red, in fact, about the topic of 3D printing jishu to make human kidneys, she was just bragging, in fact, there is no such jishu in the United States now. It's just a scientific research team that comes up with ideas.

She was intrigued at the time. I also had a very in-depth study of this 3D printing jishu, but then when I learned about the development of this 3D printing, I gave up, after all, the current 3D printing jishu is still far from realizing this ideal.

"Well, okay, Xiao Li, I just talked about the topic of 3D printing jishu to make kidneys, and it's just an idea put forward by top medical experts in the United States, and it's still early to be realized. I was also very interested in this statement after listening to this statement at the time, and later I also studied the development of this 3D printing jishu for a while. Since 1993, 3D printing jishu has been practiced by MIT people and applied for a patent, in fact, there has been a lot of debate about the practical application of this jishu, and many people think that this kind of jishu is just a flashy and sensational jishu, and his actual efficacy is simply impossible to reach as strong as others boast. After all, in some machining areas, it is impossible for him to mention traditional machining, especially metalworking. Later, MIT authorized this jishu to ZCORP to develop it, and over the years, ZCORP has spent no less than a billion dollars on this project, but it has not been able to research out a reason, so when will the specific 3D printing jishu be able to be popularized and used in a large area, this time, it is really hard to say......"

Gu Ping didn't hide anything, so she directly told Li Yifan what she knew about the development of 3D printing jishu.

And Li Yifan also stretched his brows, it seems that this 3D printing jishu is indeed not too formed, but this 3D printing jishu should go back soon.

Three years later, in 2005, the ZCORP company will soon make a breakthrough in 3D printing, and they will launch the first 3D printer that is truly suitable for the market.

AFTER 2008, DUE TO THE FINANCIAL CRISIS, THE COMPANY SPREAD A LOT OF JISHU, WHICH CREATED TWO OTHER 3D PRINTING GIANTS IN THE UNITED STATES, NAMELY STRATAHAYY AND 3DSYSTERM.

And these three companies, later in the shijie 3D printer market share, long-term occupy more than 80% of the market share.

In Europe, Germany and Israel occupy about 9.1% of the entire shijie market, while Japan and China are far behind in this data.

At that time, although there are a few so-called companies that can produce 3D printing jishu in China, but among these enterprises, there are so many enterprises with military backgrounds, and there are few companies that can really produce 3D printers.

Most of them import all the machines from abroad, put on famous brands, change some parameters, and then claim to be their own production, but in fact they are far from their own production.

Even if the 3D printer is used by the Chinese military, there are many key components purchased and imported from abroad, such as long-distance linear guides, nozzles, and application software, etc., these key components are imported from abroad.

In this field, although we started not too late, the subsequent development is really slower than others.

Of course, this is also related to our national characteristic system, in fact, there are not many domestic scientific research teams in our country that study this kind of 3D printing jishu, but in the special scientific research system of our country, these scientific research teams are destined to be tragic.

For example, after the Americans proposed this kind of 3D printing jishu, some people in China quickly noticed that this is a new field of processing and casting, if a breakthrough can be made in this field, then it will definitely occupy the commanding heights in the new generation of industrial innovation trend.

As a result, some universities or scientists in China have begun to devote themselves to research and development in this field.

Among them, the most representative is Mr. Hu Bin of Huazhong University of Science and Technology, who used to engage in optoelectronic science and research lasers.

When he was studying abroad, he accidentally noticed this kind of jishu advocated by the Americans, and he felt that this kind of jishu was very interesting.

So after returning to China, I organized a team to engage in the development of this kind of jishu.

You must know that in the early years, the so-called 3D printing jishu could only be used in the fields of plastics, rubber, nylon, resin, paraffin, gypsum and other materials, and for other fields, the expansion was not wide.

Because when you use this 3D printing jishu, you have to use high temperature to melt the material, and then spray it in the way you want, and then layer it to make the corresponding product.

But for metals, their melting point is quite high, and with the current jishu, you simply can't do it, let the metal dissolve instantly, and then spray it according to the pattern you want, superimpose.

This is also the 3D printing jishu, after being publicized, many experts do not see the key to haode, because it can not be used on a large scale in metal materials, which also talks about and replaces the traditional processing industry?

So in response to this, Mr. Hu Bin took his team to start laser sintering jishu, and it only took a few years to overcome this problem, and he is so jishu that he can target almost any granular metal.

It can even be said that the problem of how to apply 3D printing jishu to metal, which has been plaguing Americans in the early years, was solved by a Chinese team a few years later.

But it's a pity that because at this time, not many people have heard of this 3D printing jishu in China, and the superior leaders of Mr. Hu Bin are not familiar with this 3D printing jishu at all.

When you see that the team led by Mr. Hu Bin actually took the state's funding to engage in such jishu, using lasers to burn metal, and to engage in metal melting, isn't it a waste for you?

Did you do that? You're too unkind to take money as money, are you?

So the leader said, don't study it, go back to teaching, and then take out this jishu and give it to a subordinate factory of Huazhong University, and let them go to produce handicrafts......

In this way, the pearl was covered with dust, and it was not until ten years later that the Americans began to preach that they had made a breakthrough in 3D printing jishu, and they could already use this jishu to process the metal frame of their fighter jets, and the people of the Commission of Science, Technology and Industry for National Defense suddenly realized.

Then he began to send people across the country to look for talents who studied such jishu, and only then did he find Hu Bin, which made this jishu be valued again.

But the previous ten years, we wasted in vain, which cannot but be said to be a kind of sadness.

And this is the sorrow of the layman leading the insider!

And there are many such stories in the country, not only Hu Bin, but also a team, which has been researching this jishu since 2002, and it was not until this team developed the largest 3D printer in Shijie ten years later that this team was known and valued, and there is an advantage for Li Yifan, that is, this team happens to be in a university in his hometown of Bincheng......
