Of course, this 3D printing technology is definitely not as perfect as people think. Even ten years later, this new technology has only developed to a slightly successful level.

This is the result that people have achieved only when they invest hundreds of millions of dollars. If they really want to completely realize large-scale industrialization and apply it to the field of machining on a large scale, there is still a lot of way to go and astronomical funds are needed.

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

It was the first of them that scientists had designed the design concept step by step, to increasing investment in research, and then to starting a small-scale industrialization. Then everyone saw the benefits of this technology, so everyone began to increase investment in research.

After that, only the United States, Germany, and Japan remained the only one who dominated this field.

These three companies have their own unique features in the field of processing tools, and any successor who wants to reach their height will face the layers of barriers they set up.

These barriers are not only barriers in patent technology, but also barriers in pure technology. After all, in this kind of scientific research, there is no need to be any tricky tricks. You must come step by step, and after countless failures and accumulate enough experience and lessons to finally get to this point of success.

The development of any new technology does not appear out of thin air. So if our country wants to no longer lag behind the United States, Germany, and Japan as it used to be in this industrial transformation, then we must start to increase our efforts and start research in the early days of the emergence of this new technology.

This will allow us to no longer lag behind others in this great industrial transformation, leading to a step behind like the development of industrial machine tools.

Nowadays, the 3D printing technology has not attracted the attention of countries around the world. Even Americans themselves know very little about this technology. Only a few scientists from top American scientific research laboratories know the importance of such technology, and are constantly exploring and using it on a small scale.

The current 3D printing technology is still at the initial stage to a large extent, and can only process some plastic, resin, ceramic, powder and other materials, but it is not possible for metal materials with a wider application area.

After all, even the United States now does not have much intention to invest in this new technology. The traditional machining method is still the overlord of the traditional industrial field. Americans, Japanese and Germans can all gain enough sweetness in this field, and the Chinese have not yet developed to threaten these three traditional manufacturing overlords, so everyone has no sense of crisis at all and has no motivation to develop new technologies.

This 3D printing technology was truly valued by Americans. It still took a long time to wait around 2008, after Ao Xiaohei came to power, he gave a special explanation of this technology to the public, which attracted the attention of many manufacturing tycoons, and then received state funding and investment from these tycoons.

The Americans quickly developed this technology with their abundant technical reserves, and even in the field of metal processing, they quickly made large-scale breakthroughs.

Sometimes, we cannot help but envy Americans in this regard. In fact, their technical reserves are generally reserved based on the world's leading thirty years. There are many technologies we see in science fiction movies. They are not without them, but they just need to see if they are willing to use this technology and market it.

This 3D printing technology is not only a great success in the industrial field, but in fact, it is not the engineers in the processing field that pay more attention to this technology, but the medical experts.

Organ failure is a necessary path for people to age, and many organ failures in the human body are caused by tracking lesions. Medical experts who have been working to study how to increase human lifespan have been studying how to face problems such as organ failure.

In the last century, the method that everyone could use was to convert organs through external medical procedures and replace lesions or failures.

Change to other donors' healthy organs, but this donated organ is not the organ that grows from the patient itself. In addition, the DNA is different, so it will have a certain degree of rejection from the patient itself, and in severe cases, it will lead to death in the human body.

Moreover, because of the DNA arrangement of this type of replacement external organ, in order to combat the rejection caused by the patient, the patient must have long-term useless drugs to fight this rejection.

The final result is that while spending a lot of money, it will also lead to the death of such replacement organs early. Generally, the replaced organs will last only twenty years in the patient's body.

If the later maintenance measures are not appropriate, it may only last a few years, so the patient will face the problem of finding a suitable organ again.

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

The British used cloning technology to solve such problems, but because they faced a strict moral crisis, this cloning technology was strictly prohibited.

After all, the replica you cloned is also a life. People cannot clone a complete person for the sake of your deity’s life, and then kill him, and then obtain organs from his body to save your deity’s life.

Therefore, how to simply copy an organ that the human body urgently needs has become the most troublesome problem in the medical community.

It was not until the emergence of this 3D printing technology that this problem was completely solved.

After Americans increased their investment in 3D printing technology in 2008, the madmen at MIT in the United States used this technology to create bones, blood vessels, and muscle tissue that can be replaced with human body, and will not cause any repulsion with 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 Haval University in the United States used this technology and took only 7 hours to print out a kidney that can be used for transplantation. This kidney was designed based on the patient's own DNA sorting. After transplanting into the patient's body, there will be no rejection reaction. This means that in the future, the patient with kidney transplantation will not need to take any anti-rejection drugs like other kidney transplant patients.

Later, they not only used this technology to create kidneys that can be transplanted, but also lungs that can be transplanted, bladder and other human organs.

This can definitely be called a medical miracle, but after all, these technologies were only in the early stages of use and had not yet been widely used, so their reputation was not yet known.

However, as this 3D printing technology becomes more and more famous in various fields, it will become more mature, and many difficult and complicated diseases that people originally could not imagine will eventually be cured.

This is the key role of this technology in the medical field.

Li Yifan didn't think of this technology at first, because before he was reborn, this technology was just hyped up during that period, and it had not been widely used in the field of machining, nor was it widely used in the medical field. It was just a test in some industries and certain fields.

Although he had also learned about these technologies and was shocked by the changes this technology can bring to the development of the entire society, he was not a real technical expert after all, and his impression of this technology was not that deep.

Until now, Gu Ping mentioned this technology with him, and he suddenly felt as clear as if he was enlightened. Not to mention anything else, just the changes brought about by this 3D printing technology in the field of automobile manufacturing are worthy of his attention to this technology.

If you start this technology early, it will definitely be a big opportunity for me. I was still having a headache before, but after this factory grows, there will be problems in the machining field.

After all, if you want to start the automobile manufacturing industry, you cannot do without the field of precision processing.

Now I have quietly brought some machine tools from Japan, but the number of these machine tools is only more than 100. Although it will increase every year in the future, the number will definitely not keep up with the growth of my demand.

It was ten years later when Western Europe and Germany quietly relaxed the technical restrictions in the field of precision processing. By then, by the time, by introducing processing centers from Western Europe and Germany, the domestic automobile industry had probably been occupied by the Germans and Japanese, so how could it have the pie of its own?

In this field of automobile manufacturing, there are several places where tight processing is required, such as the housing of the transmission, the high-precision hydraulic valve inside, the electronically controlled forks, gear inside, etc.
