The machine on the opposite side is far from being as glamorous as Li Yifan imagined, and even looks like it can only be described as shabby.

However, when it comes to function, it is not bad at all, some metal powder, after being mixed and stirred, put it into the funnel, and then a laser is shot out of the generator, the funnel is heated, and then a part of the metal in the funnel begins to melt into a liquid state, and then enters the nozzle, and then according to the program setting, the nozzle moves back and forth on the X, Y axis of the tie rod under the control of the computer, and the liquid metal is sprayed out......

Soon after, the liquid metal was gradually formed under the cooling of an unknown liquid ejected from another nozzle......

In just an hour's effort, a flying statue of a female lady who looks like a flying lady has been formed, looking at the simple machine, but it can make such exquisite handicrafts, Li Yifan can't admire Professor Hu Bin in his heart.

To be able to use such a simple tool in such a simple environment and develop such a process technology is really very the style of our older generation of industrialists.

It is true that our machinery and equipment look far less cool and dazzling than the industrial equipment of the United States and Germany, but at least it is no worse than theirs in terms of the efficacy it should have.

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

"This equipment is a little simpler, but our financial environment is like this, so it can only be used to deal with it, and it can't be used for any industrial aesthetics, so I haven't done too much design in the shape of the shell. If it is really used to produce high-specification products in the future. That's not going to work. After all, it is dustproof and shockproof. But it's critical. And on this machine, there are a lot of equipment, all of which are not our own technology, such as the chips that control the computer, which I got from abroad, all of which were chips from EXCELLON in the United States, and then we designed and modified them ourselves. After all, we are not good at producing these things in China......"

"Oh? That's ......."

Yao Chongshan's words made Li Yifan 'shake the tiger', why did he forget this stubble.

But fortunately, Hu Bin mentioned this, hehe, after we go back, we are thinking about it and going to the United States to pick up the leaks......

Li Yifan was a little distracted by chance, and that was because Hu Bin's words suddenly reminded him of something else. And here Yao Chongshan is completely obsessed with it. Especially watching the continuous spraying of the machine, and a series of actions such as metal drawing, and finally in the air, a metal statue of a lady flying into the sky was processed.

For the first time, I watched a 3D printer complete the work at close range, and it is also our own 3D printer, and the most important thing is a machine that can use metal as raw materials to complete 3D printing work.

This makes Yao Chongshan, who is himself among the technical otakus, how can he not indulge in it?

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

It was an incremental processing of metal, but unlike anything he had seen before.

In the past, the metal processing mode he saw was all reduced processing, to put it bluntly, it was to give you a large iron ingot, put it on the fixture of the machine tool to fix, and then the machine tool replaced various tools, and then drove the motor through the servo motor, and then began to draw the dragon and the phoenix on the big iron ingot.

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

The current 3D printing technology is a completely different processing mode, which belongs to incremental processing, to put it bluntly, the model is designed by the computer, and then a series of technologies such as fast-melting and fast-drying cooling are used.

In a very short period of time, the metal processing according to the originally envisaged model is faster, more accurate, and most importantly, saves a lot of material.

It's just that in the current situation that metal 3D printing technology cannot be popularized on a large scale, the cost of his processing price is not lower than that of those processed by machine tools, but if it can be popularized on a large scale, I believe that his price and cost advantage will soon be revealed.

"Hehe, no way, business is not good now, such a lady flying statue, although it looks good, but the cost is too high, and the price is also 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 due to their low cost. So we don't use much of this metal 3D printer......"

Hu Bin explained to Li Yifan while answering Yao Chongshan's question.

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

And this Hu Bin is also a sincere person, since he has decided to give Li Yifan his life, of course, he must let people see his true ability, lest people think that he has a false reputation and can only blow.

So he took Li Yifan and Yao Chongshan to the workshop of the metal 3D printer that he usually treasured, and also operated it himself, and processed a metal lady flying statue for them to see, so as not to be thought that he couldn't practice.

Li Yifan is very satisfied with Hu Bin's sincerity, and is even more shocked by Hu Bin's preliminary research, this is still the scientific research results of people a few years ago, and it has not been improved because of financial problems in the later period.

Although he is a layman, he can also see that this product is only in its infancy, and there are defects of one kind or another, but none of this matters.

The most important thing is that the foundation of the family has been laid, and it is very down-to-earth, as long as you continue to spend money in it, I believe that you will soon be able to produce results.

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

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

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

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

And the moment Li Yifan saw Hu Bin signing his name on the contract, he suddenly had a feeling that he had completed the construction of his industrial empire.

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

Now that Hu Bin has become his own person, Li Yifan feels that there is no need for him to hide, and directly asked the question in his heart.

"Hehe, Japanese? What kind of kindness can you have when you come? I don't know where they got the news, so I have a ready-made powder metal laser sintering technology about 3D printing, so they came over to take a look, they have been in contact with me for a long time, and I only recently promised them to let them come and have a look. ”

Hearing Hu Bin say this, Li Yifan's heart tightened, these Japanese are really dog-nosed goods, and if they smell something fishy, they will rush over immediately, these guys are not good characters, I don't know if this Hu Bin has leaked the secret technology to them.

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

"Hahaha, how can it? How could I leak that technology to them, you must know that this technology is my heart's meat, but it was the result of so long time and hard work with my team. How could I possibly tell them such a critical technical secret? Besides, what good intentions can these little Japan have? Don't think that I don't know their little bit of fancy intestines because I'm engaged in research, over the years, they have gone from our side to get less good things? But what did they give us back? Hum! Do you really think that we Chinese people have no backbone at all, as long as we give some money, we will become dogs wagging their tails at meat and bones? ”

Speaking of those Japanese, Hu Bin's eyes were full of disdain, and Li Yifan was also relieved at this time, fortunately, this Professor Hu Bin is still a relatively disciplined scientist.

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

Li Yifan suddenly smiled gloomily and said to Hu Bin, at this time, he had already thought about it again, he was going to dig a pit for the Japanese, didn't you want to take advantage of it?

Let's see, who is the hunter and the prey at any time?

But Hu Bin and Yao Chongshan couldn't understand Li Yifan's intentions for a while, and when they heard Li Yifan say this, they couldn't help but look stunned, especially Yao Chongshan, who was already young and vigorous, and when he heard Li Yifan's words at this time, he almost slapped the table out of anger.

"Hehe, listen to me, I'm not talking about giving them real technology, but ...... like this" (to be continued......
