When the 3D printing jishu mentioned by Gu Ping entered Li Yifan's ears, Li Yifan only felt that his head was booming, as if he had suddenly been pushed open a brand new door.

3D printing jishu,This is a kind of jishu that is known as the beginning of the third industrial revolution.,I actually forgot such an important jishu.,It's really ......

Fortunately, Gu Ping inadvertently mentioned such a statement here, otherwise he would have forgotten such an important jishu in his mind.

Speaking of this 3D printing jishu, it first emerged in the United States, as early as the eighties of the last century, a company in the United States took the lead in making a so-called 3D printer, but that was just a gimmick.

It was the freaks at the Massachusetts Institute of Technology in the United States who really developed this kind of jishu and applied it, and in 1993, they completed a series of mature jishu and applied for a patent.

However, at that time, due to some restrictions on jishu and materials, 3D printing jishu at that time was more used in some less practical fields.

The large industrial manufacturers of Shijie do not pay much attention to this jishu, after all, this jishu has just been born, the conditions for large-scale application are not mature, and the cost is quite high, so everyone is not very interested in this jishu.

After the new century of metals, with the slowdown of global economic growth and the rise of labor costs, more and more jobs have passed to China, and the manufacturing industry in the United States was once very worried about this situation, and they are wondering how to take back these job opportunities.

And this has promoted their increased investment in 3D printing jishu. Later, when O'Xiaohei served as the second president of the United States. When the State of the Union address for that year is read. He even once listed the 3D freshman jishu as an opportunity for the third industrial revolution in the United States, so that major companies have increased their research and development efforts on this jishu.

And it was after that, the Americans' 3D printing jishu began to advance by leaps and bounds, at the end of the first decade of the 21st century, this kind of 3D printing jishu began to be rapidly promoted, and in many low-end and high-end manufacturing fields, began to be widely used.

That's from that time. Many low-end jobs that require a large number of manual manufacturing have begun to flow back to the United States, and in the United States, these jobs are no longer artificial manufacturing, but are completed by 3D printing jishu, such as clothing, toy manufacturing, etc., the low-end types of manufacturing have been made in China and began to transform to American manufacturing on a large scale.

What exactly is the magic of this 3D printing jishu that will make people so fascinated? And list it as the beginning of the third industrial revolution.

In fact, it is mainly due to the precision of this new type of manufacturing jishu. and production efficiency, even compared to those high-end industrial machine tools. It's not too much to say.

At the most basic level, in terms of cost savings, this kind of jishu is much more powerful than the machining industry that is now used in large areas.

Now the mainstream application of industrial machining jishu, a large area of use is reduced processing, and this processing method will produce great waste, and 3D printing jishu uses incremental processing, in this way, just in terms of material cost savings, it will be compared with the existing processing methods, leaving a large amount of overhead.

For example, the titanium alloy frame of the F22 fighter made by the Americans, because of its special shape, cannot be processed in one piece, so it is necessary to use a large special alloy for machining, and to zuihou it is necessary to use a very special laser welding jishu for welding.

It is said that a fighter jet, just to produce the raw materials of this titanium alloy frame, the waste of materials in the processing, is as high as 92 percent, plus other losses, Zuihou's material utilization rate, is less than four percent.

That is to say, the weight of the titanium alloy overall frame of an F22 fighter is only more than 100 kilograms, but the raw materials needed to process this frame are as high as about one ton, which shows the seriousness of the waste of materials in the traditional machining industry.

On the contrary, if this kind of 3D printing jishu is used, there will be no such material waste problem, and if the operation is done properly, the laser welding jishu that needs to be used inside can be completely abandoned, and the integrated molding can be directly achieved, which not only saves time and effort, saves materials, but also ensures that the strength of the overall frame is higher.

As long as you have a good program on the computer, then you can use a large printer, plus laser sintering jishu, and start working, maybe only a few hours of work, and you can complete the job.

This kind of processing process sounds a bit fantastical, but ten years later, such a jishu really appeared, and it was the first to be applied by the Americans in their fighter jet processing field.

And not only the Americans are using, we are also using, after ten years, the research and development of China's fighter jets has been accelerated, and the fifth generation fighter was soon launched.

It is precisely because of the emergence of this kind of 3D printing jishu that it balances the shortcomings of our country in some precision machining fields, so that we can quickly overtake in corners, quickly complete manufacturing in a certain field, and get rid of the traditional precision machining industry and reach the international leading level.

But even so, ten years later, the most haode who played 3D printing jishu was still American, and at that time, three-quarters of the 3D printed products of the whole shijie every year were from the United States, and the remaining quarter was divided by other countries.

At that time, the products produced by Huaguo's 3D printing jishu only accounted for 3.7% of the total market score, which is completely incomparable with the share of the Americans, but fortunately, the Japanese and Germans also walked behind in the early days of this industrial revolution, and their share was not even as good as ours.

But in Europe, the Israelis have gone farther, and of course this has a lot to do with the fact that they have always maintained close ties with the United States.

Such a situation, of course, has a lot to do with the consistent lack of attention to Jishu in China, as well as the consistent lack of attention to Jishu talents.

In fact, this 3D printing jishu, in Li Yifan's view, is a very haode opportunity for our country to catch up with developed precision machining manufacturing countries such as Germany and Japan in the field of precision machining.

Because this jishu is different from the traditional mode of using CNC machining centers for traditional reduction machining, this is a new processing mode.

And different from the traditional processing mode, he can not only save materials in a large area of materials, but also save time, improve efficiency and even save costs compared with the traditional processing mode in the manufacturing process.

For example, some more complex curved workpieces, such workpieces, can not be processed by those machine tools at one time, must be divided into several parts and components for sectional processing, and after the processing is completed, different welding methods are used to weld.

Moreover, in the processing and later welding engineering, great attention must be paid to ensure the overall accuracy of the workpiece after processing.

With 3D printing, you don't have to worry about this at all, as long as you design the control program on the computer, and then you can let the 3D printer work on its own.

He will process it step by step according to the incremental pattern, and this process is like you see an industrial work, like an agricultural crop, according to the standard of their DNA ordering, and then grow it in the printhead of a 3D printer.

The whole process not only does not waste materials, but also saves a lot of complicated processing processes, greatly improves the efficiency of processing, and saves costs.

For example, the landing gear used in the fifth-generation fighter launched by our country in later generations, and the titanium alloy frame of the combat cockpit are processed with this jishu.

Titanium alloy is very difficult to process because of its high hardness, which is well known in the processing field, and we have always been in this field of finishing, because of the limitations of jishu, there are great defects and shortcomings, and the emergence of this 3D printing jishu just makes up for our shortcomings and shortcomings.

But after all, our country's scientific and technological foundation and attention to this new jishu are not as strong as the Americans, so in many fields, we are still much behind the Americans.

And in this life, when Gu Ping mentioned this jishu very accidentally in front of Li Yifan, Li Yifan was hot, feeling that God had pushed a door open for him in front of him.

A door that can allow yourself to overtake in the industrial field and quickly catch up with the top international enterprises.

This 3D printing jishu is indeed good enough, although even after ten years of development, it is still difficult to replace the traditional manufacturing industry, especially those processing centers.

But that's just because of the limitations of materials, and I believe that this new jishu will replace the traditional manufacturing and processing center sooner or later, which is the consistent understanding of people of insight.

Ten years later, many people in China realized this and began to invest vigorously in this industry, but at that time, they began to invest in the research and development of this new field, which seemed a little late.

Such a good thing, in Li Yifan's opinion, is definitely not too late.

The sooner you enter this industry, the more you will be able to eat the biggest piece of cream on the cake in the future.

What's more, this 3D printing jishu is closely related to the industry he wants to engage in in the future.

For example, the automobile manufacturing industry, which he values very much, or the medical field that Gu Ping just mentioned, this kind of jishu will have a revolutionary impact on these two industries. (To be continued......)
