"Xiao Li, what are you thinking?"

Gu Ping and Li Yifan talked about her imagination about the medical field. Unexpectedly, the 3D printing technology she mentioned accidentally made Li Yifan lose his mind and suddenly remembered a lot of things about the ins and outs of this technology, and there are also benefits.

Li Yifan was distracted and walked for more than ten minutes. He was thinking too much. At the beginning, Gu Ping didn't care, but later she saw that Li Yifan didn't speak for more than ten minutes and still had a thoughtful expression on her face. So she couldn't help but push Li Yifan and asked.

"Oh...well... I'm sorry, Sister Ping, I was also attracted by the 3D printing technology you mentioned just now, which was so distracted. When I was in Jingshi University, I had a lecture at a certain physics teacher. I talked about this technology, which was very interesting and interesting to hear it at that time. But afterwards, I didn't take it to heart, but now I heard that you talk about this technology, which has begun to be initially applied in the United States, and even some medical experts have begun to try to use this technology to make kidneys. I was very surprised and thoughtful... Hehe, I'm a little distracted, don't be surprised..."

"Hey! What are you guys, especially those from science and engineering, no wonder they say you are a technician. If you mention a certain technology, you will be full of thoughts. Forget it, I am not surprised."

Gu Ping understood as soon as she heard this. She had come into contact with people like science more and knew that they had such problems. Especially when talking and chatting together, if you mention a technique that they are very interested in.

They either broke the casserole and asked to the end. Or they would be distracted by random thoughts on the spot. She had encountered many such situations, so she was used to it.

"By the way, has Sister Ping developed very well in the United States now? Those doctors have already started using this technology to help people replicate their kidneys?"

Li Yifan remembers it very clearly that Americans have made a real breakthrough. When they arrived in this field, it should have been ten years later, and it was the breakthrough of Haval's medical team.

However, Gu Ping just said that Americans have already started to have this idea, and he also wanted to know where the Americans have now taken action.

When Gu Ping heard Li Yifan ask this, her face turned red. In fact, she is just bragging about the topic of 3D printing technology to create human kidneys. In fact, there is no such technology in the United States now. It is just a scientific research team that puts forward the concept.

She was very interested at that time. She had also studied this 3D printing technology in depth, but later she learned about the development of this 3D printing, and gave up. After all, the current 3D printing technology is still far from realizing this ideal.

"Well, okay, Xiao Li, I just talked about the topic of 3D printing technology to create kidneys. It is just an idea proposed by the top medical experts in the United States. It is still early to realize it. I was also very interested in this statement after listening to this statement. Later, I also studied the development of this 3D printing technology for a while. Since 3D printing technology was practiced by MIT in 1993 and applied for a patent, in fact, there has been a lot of debate about the practical application of this technology. Many people think that this technology is just a flashy and unrealistic.

It is just a sensational technology, and its actual effect is simply impossible to reach as strong as others boast. After all, in some processing fields, it is impossible for him to mention traditional machining, especially metal processing. Later, MIT authorized this technology to zcorp for research and development. Over the years, zcorp has spent more than one billion dollars on this project, but it has not yet been able to figure out the reason. So when will this 3D printing technology be promoted and used on a large scale? It is hard to say at this time..."

Gu Ping didn't hide anything, but told Li Yifan directly about the development experience of 3D printing technology she knew.

Li Yifan also relaxed his eyebrows. It seems that this 3D printing technology has not yet been formed, but this 3D printing technology should be a breakthrough 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 technology outward, which created two other 3D printing giants in the United States, namely stratayay and 3Dsystem.

These three companies later occupied more than 80% of the world's 3D printer market in the world.

In Europe, Germany and Israel account for about 9.1% of the world market, while Japan and China are both far behind in this data.

By that time, although there were several so-called companies in China that could produce 3D printing technology, there were a few companies with military backgrounds in these companies that could produce 3D printers at a time and at a time.

Most of them introduce all machines from abroad, put on famous brands, change some parameters, and then claim that they are produced by themselves. In fact, they are still far from being self-produced.

Even when I use 3D printers, there are many key components that are purchased and imported from abroad, such as long-distance linear guides, nozzles, and application software. These key components are imported from abroad.

In this field, although we did not start too late, our subsequent development is really slower than others.

Of course, this is also related to our country's characteristic system. In fact, there are not many domestic scientific research teams studying this 3D printing technology. However, in our country's special scientific research system, these scientific research teams are destined to be tragic.

For example, after Americans proposed this 3D printing technology, some people in China soon noticed that this is a brand new field of processing and casting. If breakthroughs can be made in this field, it will definitely occupy the commanding heights in the new generation of industrial innovation trends.

So some universities or scientists in China began to devote themselves to this field to research and development.

The most representative of these is Mr. Hu Bin from Huazhong University of Science and Technology. He used to be engaged in optoelectronics and studied lasers.

When he was studying abroad, he accidentally noticed the technology advocated by Americans, and felt that this technology was very confusing.

So after returning to China, he organized a team to develop this technology.

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

Because when you use this 3D printing technology, you must use high temperature to melt the material, and then spray and superimpose it in the way you want to create the corresponding product.

But for metals, their melting point is quite high, and according to current technology, it is simply impossible for you to make the metal dissolve immediately, and then spray and superimpose according to the pattern you want.

This is also the key to the 3D printing technology that was not optimistic about by many experts after it was promoted, because it cannot be used on a large scale in metal materials. Is this a matter of replacing the traditional processing industry?

So to address this point, Mr. Hu Bin led his team to start laser sintering technology, and in just a few years he solved this problem. Moreover, his skill is so good that he can target almost any granular metal.

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

But unfortunately, at this time, not many people in China have heard of this 3D printing technology, and the superiors of Mr. Hu Bin are not familiar with this 3D printing technology at all.

Seeing that the team led by Teacher Hu Bin actually used the state's grant to develop such technology, using lasers to burn metal and melt metal, isn't you wasting it?

Is there anything you did? You are too ignorant of using money as money, right?

So the leader said, "Don't study it anymore, go back to teach, and then took out this technology and gave it to a subsidiary factory of Central China University, and asked them to produce handicrafts...

Just like this, the pearl was covered with dust. This technology was in decline for ten years. Until ten years later, the Americans began to promote their breakthrough in 3D printing technology and could already use this technology to process the metal frame of their fighter jets. The National Defense Science and Technology Commission's personnel suddenly realized.

Then he began to send people nationwide to look for talents who are studying such technology, and then he found Hu Bin and made this technology pay attention to again.

But we have wasted the past ten years in vain, which is a kind of sadness.

And this is also the sorrow of laymen leading experts!
