Of course, this kind of 3D printing jishu is definitely not as perfect as people recognize, even after ten years, this new jishu is only developing to the point of a slight success.

This is still people in the case of investing hundreds of millions of dollars, the results to be achieved, if you really want to put this jishu, completely realize large-scale industrialization, a wide range of applications in the field of machining, there is still a long way to go, but also need to invest astronomical funds.

But after all, such jishu, the sooner you invest, the better, because according to the development history of the current CNC machine tools, you will know that even the CNC machine tools that are now used on a large scale have come over like this when they were born more than 50 years ago.

At first, it was the design concept of scientists, then it was the design of people step by step, then it was more invested in research, and then it began to industrialize on a small scale, and then everyone saw the benefits of this jishu, so everyone began to invest more in research.

After that, only the United States, Germany, and Japan were left to dominate in this field.

And these three, in the field of this kind of processing tools, have their own uniqueness, and any follow-up chaser, if they want to reach their height, will face the layers of barriers they have set up.

These barriers,Not only in the patent jishu barriers,There are also pure jishu barriers,After all, in this kind of scientific research,There is no room for any cheating,You have to come step by step,After countless failures,Accumulate enough lessons and lessons,Will make you zuihou come to this step of success。

Any new jishu development. None of them appeared out of thin air. So if we want to be in this industrial revolution. No longer lagging behind the United States, Germany, and Japan as before, then it is necessary to start investing more and start researching in the early days of the emergence of this new jishu.

In this way, we can no longer lag behind others in this industrial change, resulting in the development of industrial machine tools. If you are one step behind, you will be one step behind.

Now this year's 3D printing jishu, has not attracted the attention of shijie countries, even the Americans themselves, this kind of jishu, also know very little, only a few of the top scientific research laboratory scientists in the United States, know the importance of such jishu, and continue to explore, and a small range of use.

Now 3D printing jishu. To a large extent, it is still in the initial stage, and can only be used for some plastics. Resin, ceramic, powder and other materials are processed, but for metal materials with a wider range of applications, it is not at all.

After all, even if it is the United States itself, there is not much intention to increase investment in this new jishu, and now the traditional machining method is still the hegemon of the traditional industrial field, the Americans and the Japanese, the Germans, can get enough sweetness in this field, and the Chinese have not yet developed to threaten the meaning of the three traditional manufacturing overlords, so we have no sense of crisis at all, and there is no motivation to develop a new jishu.

This kind of 3D printing jishu really began to be valued by Americans, or until around 2008, after Ao Xiaohei came to power, he gave a special national explanation to this jishu, which attracted the attention of many manufacturing tycoons, and then obtained state grants and capital injections from these tycoons.

And the Americans soon relied on their abundant jishu reserves, and soon developed this jishu, and even in the field of metal processing, they soon made a large-scale breakthrough.

Sometimes, we can't help but envy the Americans in this regard, in fact, their jishu reserves, generally according to the leading shijie thirty years of reserves, there are a lot of jishu we see in science fiction movies, they don't have nothing, but it depends on whether they are willing to take out this kind of jishu and market it.

And this kind of 3D printing jishu is not only a great success in the industrial field, in fact, it is not those engineers in the processing field who pay more attention to this kind of jishu, but those medical experts.

Organ failure is the only way for people to age too much, and many human organ failure is caused by tracking lesions, and medical experts who have been working on how to increase human lifespan have also been studying how to face the problem of organ failure.

In the last century, the method that everyone could use was to carry out organ conversion through external medical surgery, and replace diseased or failing organs.

Replace the healthy organs of other donors, but this kind of donated organs, after all, are not the organs grown by the patient itself, plus the difference in DNA, so it will have a certain degree of rejection with the patient itself, and in serious cases, it will lead to human death.

Moreover, because the DNA arrangement of this replacement external organ is different from the patient's own organs, in order to combat the resulting rejection, the patient must use long-term useless drugs to fight against this rejection.

The end result is that a lot of money will be spent, and the replacement organ will die early, and the survival time of the replaced organ in the patient's body is usually only 20 years.

If the maintenance measures are not done properly, then the life span may only be a few years, so the patient will have to face the problem of finding a suitable organ again.

In modern society, there are not many people who are willing to donate organs, so human organ donation has always been a serious problem faced by the medical community.

The British once used to clone jishu to solve such a problem, but because they faced a strict moral crisis, this kind of cloned jishu was strictly forbidden to be used.

After all, the clone you clone is also a life, and people can't clone a whole person for the sake of your deity's life, and then kill him, and then take organs from his body to save your deity's life.

Therefore, how to simply replicate an organ that the human body urgently needs has become the most headache for the medical community.

It wasn't until the advent of this kind of 3D printing that this problem was completely solved.

In 2008, after the Americans increased their investment in 3D printing jishu, the crazy people at the Massachusetts Institute of Technology in the United States used this jishu in only two years to create bones, blood vessels, and muscle tissues that can be replaced with the human body, and there will be no rejection of the body, the funniest thing is that even after the bones are replaced, they will adapt well in the human body, and continue to grow......

In 2011, a medical team at Harvard University in the United States used this kind of jishu to print out a kidney that can be used for transplantation in only 7 hours, and this kidney is still designed according to the DNA sequencing of the patient itself, and will not produce any rejection after transplantation into the patient's body, which means that in the future, the kidney transplant patient does not need to take any anti-rejection drugs like other kidney transplant patients.

Later, they used not only the jishu to create transplantable kidneys, but also transplantable lungs, bladders, and a series of other human organs.

This is definitely a miracle in medicine, but after all, at that time, these jishu were only in the early stages of use, and they had not yet been used on a large scale, so their reputation was still unexpectedly loud.

But with this kind of 3D printing jishu, the reputation in various fields is getting louder and louder, this kind of jishu will become more and more mature, and many people who were originally unimaginable incurable diseases will eventually be cured.

This is where the key role of this jishu in the medical field lies.

Li Yifan didn't think much of this jishu originally, completely because before he was reborn, during that time, this kind of jishu had just been hyped up, and it had not been applied to the machining field on a large scale, nor was it widely used in the medical field, but it was just a test in some industries and some fields.

Although he had also learned about these jishu, and was shocked by the changes that this jishu could bring to the development of the whole society, he was not a real jishu expert after all, and his impression of this kind of jishu was not so deep.

Until this moment, Gu Ping mentioned this jishu to him, and he suddenly felt as if he was awake like an enlightenment, not to mention anything else, just to say that this 3D printing jishu, in the field of automobile manufacturing, brought about by the change, is worthy of his attention to this jishu.

If this jishu starts early, then it is definitely a big opportunity for yourself, and you are still having a headache before, after this factory becomes bigger, this problem in the field of machining.

After all, if you want to engage in the automobile manufacturing industry, you can't do without the field of precision machining.

And now I have quietly got some machine tools from Japan, but the number of these machine tools, at best, is only more than 100 units, although it will increase every year in the future, but the number will certainly not keep up with the growth of their own demand.

And by the time Western Europe and Germany quietly let go of the jishu restrictions in the field of precision machining, it was already ten years later, and by that time, relying on the introduction of machining centers from Western Europe and Germany, I am afraid that the domestic automobile industry has already been occupied by the Germans and the Japanese.

In this field of automobile manufacturing, there are several places that need to be tightly processed, such as the housing of the transmission, the high-precision hydraulic valve inside, and the electronically controlled fork, gear, etc.

And the same is true for the cylinder block of the engine and the cylinder head, if I remember correctly, these things, ten years later, seem to be able to be produced with 3D printing jishu, right? (To be continued......)
