The machine opposite is far less glamorous than Li Yifan imagined, and even looks simple and can only be described as simple.

However, when it comes to function, it is not bad at all. Some metal powder is mixed and stirred, and then a laser is emitted from the generator to heat the funnel. Then a part of the metal in the funnel begins to melt into liquid state, and then enters the nozzle. Then, according to the program settings, the nozzle moves back and forth on the X and Y axis of the horizontal pull rod under the control of the computer to spray the liquid metal out...

Soon afterwards, the liquid metal gradually formed under the cooling of the unknown liquid sprayed from another nozzle...

In just one hour, a flying statue of a female lady with a flying look was formed. Looking at the extremely simple machine, she could create such exquisite handicrafts, Li Yifan couldn't admire Professor Hu Bin.

Being able to use such simple tools to develop such process technology in such a simple environment is really like the style of our older generation of industrialists.

Indeed, our mechanical equipment looks far less than the industrial equipment of the United States and Germany, so cool and dazzling, but at least it is no worse than theirs in terms of their effects.

Hu Bin, who was standing beside them, was rubbing his hands at this time, and he introduced Li Yifan and Yao Chongshan with a look of pride and shy expression on his face.

"This equipment is a bit simple, but our capital environment is just like this, so we can only deal with it. We can't use it. We can't do much design on the appearance and shell. If we really use it to produce high-standard products in the future, it won't work. After all, it's dust-proof and shock-proof, which is very important. Moreover, there are many equipment on this machine, but they are not our own technology, such as the chips that control computers. These are all obtained from abroad, from EXCELLON, the United States, where we can find chips, and then we design and modify them ourselves. After all, we are not good at producing these things in China..."

"Oh? That's it..."

Yao Chongshan's words made Li Yifan's body shaking. How could he forget this?

Fortunately, Hu Bin mentioned this, haha, after going back, we are thinking hard and going to the United States to pick up the bargain...

Li Yifan was a little distracted by chance. That was because of Hu Bin's words. He suddenly remembered something else, and Yao Chongshan was completely obsessed with it, especially watching the machine constantly spraying and performing a series of actions such as metal wire drawing. Finally, he processed a metal statue of a lady flying in the sky out of thin air.

The first time I watched a 3D printer complete the work with my own eyes, and it was the 3D printer that belongs to us Chinese people. The most important thing is a machine that can use metal as raw materials to complete the 3D printing work.

How can Yao Chongshan, who is one of the technical otakus, not be addicted to this?

When the machine completed the last work, Yao Chongshan immediately rushed to the front of the machine, began to look carefully, and then kept asking Hu Bin behind him.

This incremental metal processing is different from any processing mode he has seen before.

The metal processing modes he saw before were all reduced processing. To put it bluntly, it is to give you a large iron ingot, put it on the fixture of the machine tool, and then replace various tools with the machine tool, drive the motor through the servo motor, and then start to draw a dragon and stab the phoenix on the large iron ingot.

Finally, a mechanical part can be processed in the constant roar and the splashing iron filings.

The 3D printing technology in front of us is a completely different processing mode, which belongs to incremental processing. To put it bluntly, it is to design the model through a computer, and then use a series of technologies such as fast melting and fast drying cooling.

In a very short time, metal processing is carried out according to the originally expected model. This processing is faster and more accurate. The most important thing is to save a lot of materials.

However, when metal 3D printing technology cannot be widely popularized on a large scale, its processing price cost is not lower than that of those process processes that use machine tools. However, if it can be popularized on a large scale, I believe that its price cost advantage will soon be revealed.

"Haha, there is no way. The business is not easy to do now. Although such a lady's flying statue looks very good, the cost is too high and the price is very expensive, so the market response is not very good. Those made of other materials, such as ceramics or plastics, are very popular in the market. So we don't actually use many metal 3D printers..."

While answering Yao Chongshan’s questions, Hu Bin explained to Li Yifan.

In fact, Hu Bin came to find Li Yifan and the others early this morning. Of course, Li Yifan knew what he meant, and of course he would not expose it.

Hu Bin is also a honest person. Since he has decided to work hard for Li Yifan, of course he has to let others see his true abilities, so as not to think that he has nothing but a false reputation and can only brag.

So he brought Li Yifan and Yao Chongshan to the workshop of his usual treasured metal 3D printer, and also personally operated it, and processed a metal lady flying statue for them to see it, so that people would not think that they would just say nothing but practice.

Li Yifan was very satisfied with Hu Bin's sincerity, and was even more shocked by Hu Bin's preliminary research. This was the scientific research result a few years ago. Later, due to funding issues, it was not improved. If there were sufficient funds, I believe that they would have produced a more perfect finished product.

Although he is an amateur, he can also see that this product is only in the early stage and has defects of one kind or another, but these are not important.

The most important thing is that the foundation of others has been laid and is very down-to-earth. As long as you spend money on it, you believe that you will get results soon.

"Haha, it's really good enough. It's almost noon. Professor Hu, let's find a place to have a meal and sign the contract by the way."

Li Yifan waved his hand and said to Hu Bin boldly. Hu Bin, who had already made up his mind, did not hesitate this time and followed them to the hotel directly.

As soon as he sat down in the private room, before the meal came, Hu Bin had already received the contract that Li Yifan mentioned...

Hu Bin carefully checked the content of the contract, mainly about the Li Group's regulations on scientific research investment and some terms involving him, and felt that the other party was very sincere, and he was also very satisfied with some personal terms. So without saying a word, he signed his name on the contract.

The moment Li Yifan saw Hu Bin signing his name on the contract, he suddenly felt like he was done, and finally he had another important puzzle to complete the construction of his own industrial empire.

"By the way, Professor Hu, when we first arrived at your factory that day, we saw that there seemed to be someone visiting, and those people seemed to be Japanese? Please forgive me for taking the liberty, what are they here to do? I'm a little curious!"

Since Hu Bin has become his own person, Li Yifan feels that there is no need to hide, so he directly asks out the questions in his heart.

"Haha, are you Japanese? What kind of good intentions can you have when you come? I don't know where they got the news, so I have ready-made powder metal laser sintering technology for 3D printing, so they came over to see it. I have been contacting me for a long time before, and recently I promised them to let them come over and see it."

When Li Yifan heard Hu Bin say this, his heart suddenly tightened. These Japanese people were indeed dog-nosed goods. When they smelled the fishy smell, they would come immediately. These guys are not good characters. I wonder if Hu Bin had leaked the secret technology to them.

"Professor Hu, do you have this powder metal laser sintering technology..."

"Hahaha, how can I miss that technology? You have to know that this technology is my heart. Back then, I took my team and spent so long and hard work together. How could I tell them such a key technical secret? Besides, what can these little Japanese have to think that I am doing research without knowing their colorful intestines. Over the years, have they been working on our side? But what are they giving us back? Humph! Do you really think that we Chinese people have no backbone at all. As long as you give some money, they will become dogs wagging their tails at meat bones?"

When talking about those Japanese, Hu Bin's eyes were full of disdain, and Li Yifan breathed a sigh of relief at this time. Fortunately, Professor Hu Bin was still a more honest scientific worker.

"By the way, Professor Hu, since these Japanese people like to inquire about this 3D printing technology, we might as well give them some. What do you think?"

Li Yifan suddenly smiled gloomy and said to Hu Bin, he had already thought about it again and wanted to dig a hole for the Japanese. Don’t you want to take advantage of it?

Let’s see where to see who is the hunter and prey at any time?

However, Hu Bin and Yao Chongshan were unable to understand Li Yifan's intention for a while. When they heard Li Yifan say this, they couldn't help but look stunned. Especially Yao Chongshan, who was young and energetic, almost slapped the table with angrily when he heard Li Yifan's words.
Chapter completed!
