At this stage, the domestic automobile manufacturing field, especially independent car companies, is just starting, from the modern car shape design, to the manufacturing of the two key internal components, guess just begun.

As a person who has come over, looking at the beginning of China's automobile manufacturing industry, at this stage, it is still in a stage of introducing jishu imitation.

Not to mention several large domestic automobile companies, after more than ten years of cooperation with foreign car companies, they have basically lost the power and ability of independent research and development.

The major components of the automobile are directly imported from foreign countries, and then returned to the country to assemble, and they can obtain huge profits by relying on the country's policy support and selling them in the market.

And they not only do not innovate independently, but also ruthlessly strangle many private and independent counterparts in China, for example, in the production license of civilian passenger cars, they use the background of state-owned enterprises to suppress and restrict private enterprises.

For the sake of a civilian passenger car license, Chery had to take out part of its shares to SAIC in vain in exchange for a production license, and took the initiative to transform itself into a state-owned enterprise, which was already doomed to his decline ten years later.

Geely, another private enterprise, tossed up and down for seven or eight years for this birth permit before it got the birth permit.

During this time, these joint ventures have already adjusted their marketing strategies in China and completely occupied the domestic market.

And wait until ten years later. These state enterprises. In terms of independent research and development. At a time when it is still lackluster, these private independent enterprises have launched a charge in the field of independent research and development.

However, because Jishu is too backward, he has to be stuck by foreign-funded enterprises, resulting in many Jishu being backward Jishu who can't keep up, the international mainstream Jishu.

For example, in the two major fields of engine and transmission, the domestic will be ten years later. In addition to that BYD, Ken spent a lot of money in this field, engaged in reverse engineering, researched it himself, and came up with results.

Any other car company, in this field, has to rely on the introduction of parts from abroad and the return of China to assemble, in order to barely cope with things.

This is the sadness of not having an autonomous jishu!

If you get involved in the field of 3D printing as early as possible, it can be completely given to domestic automobile manufacturers. Offers an opportunity to overtake in very haode corners.

Ten years later, 3Djishu developed. Although it is not enough to completely replace the machining field of the entire automobile manufacturing industry, in some key parts, the application of 3Djishu can replace the original machining jishu to a large extent.

For example, ten years later, General Motors and Ford have begun to use this kind of jishu on a large scale to manufacture the shell of the gearbox, forks, gears, and other key parts, and even the cylinders and pistons of the engine, they can also be manufactured.

As a result, the cost was reduced on a large scale, and they began to sound the clarion call for large-scale rework.

Among them, the most representative company is Ford.

Before the subprime mortgage crisis broke out in the United States in 2008, the three auto companies in the United States have always paid the least attention to the application of new jishu and the international market.

In their view, the United States is the largest car market on Shijie, and the products they produce are the representatives of American manufacturing, and the American people with a strong sense of national pride, regardless of their products, will pay for their products.

They just need to cater to the needs of Americans, to make products that cater to American tastes.

So they have always insisted that the engine with large fuel consumption and high power V6, or V8 engine, does not pay attention to the research and development of small displacement engines at all, because in their opinion, as long as they can keep the American market, there is no need for other product development.

However, the subprime mortgage crisis in 2008 dealt them a heavy blow, because of the lack of money and the skyrocketing price of oil on an international scale, even the American people, who have always been bold, could not afford to drive such a fuel-efficient car.

Energy saving and emission reduction have become the mainstream concept of the entire automotive industry for a while, so how to ensure the high power of the engine in the case of using a small displacement engine has become the key.

As a result, various new jishu began to appear in turn, and the turbocharged jishu, which was originally a high-end jishu, began to spread in the development area, and the in-cylinder direct injection jishu also began to be used in small displacement engines in a large area.

And the most haode in this regard is the only one left in the economic crisis made in the United States, that is, the American Ford!

In addition, Ford has also changed their previous business mode of not paying attention to the market and the experience of foreign users, and has begun to develop a variety of models that suit the tastes of consumers in various countries.

Developing a brand new model is not a simple matter, and if you want to innovate, then you must comply with the laws of the automotive industry to develop new cars.

In general, it takes 36 months to develop a new car in the field of automobile design.

And the first eighteen months of these thirty-six months, which is the so-called idea formation period, are the most time-consuming and cost-consuming.

In the past 18 months, designers have drawn their ideas from their minds to the computer, and then through the means of computer combined machining, they began to shape the model, from the first small model of 1:4 to the large model of 1:1.

Any part of the vehicle must be turned into a physical model through colored clay, and the manufacture of this physical model will take at least about a year.

The manufacture of one of the intake manifolds and exhaust manifolds took six months, which shows that the time and cost of manufacturing this model is wasted.

Before there was no 3D printing jishu, designers needed to rely on computers and machining centers to manufacture such models, and some key components had to be manufactured by themselves, which was very time-consuming, labor-intensive and cost-consuming.

With 3D printing, designers can shorten the total market from computer design to one-to-one model manufacturing to as little as four months.

Not only does it save 14 months, but it also saves a lot of costs, and it can also increase the speed of car replacement, greatly outperforming other competitors.

Ford, on the other hand, is one of the companies with the most comprehensive experience in this regard, and the Ford of later generations, especially after 2010, has been pushing the boundaries much faster than ever before.

This has allowed them to win the hearts of consumers in the market, coupled with the new engine they integrated with the new jishu, which has become the first choice of Shijie top ten engines for several years, which allows them to quickly get rid of their previous slow and bulky image.

And quickly turned losses into profits, becoming one of the three major American auto giants, taking the lead in getting out of the quagmire after the economic crisis, and quickly turning into a profitable company.

After tasting the sweetness, Ford has increased the application of this 3D printing jishu, and applied it to more and more fields, which also made them quickly embark on the road of catching up, Toyota, and Volkswagen on the road of development.

Even in just two years, Ford has relied on the application of the new jishu to return to the top five of Shijie automobile manufacturing giants, and it is believed that soon, they will be able to enter the top three.

This shows the importance of a new jishu for an enterprise and even an industry.

Huaguo's automobile development, in the car design of this part, itself is a weakness, Chery, and Geely, at the very beginning, have designed a lot of strange models.

On the one hand, it is because the designers are inexperienced, and on the other hand, it is also because they simply do not have a mature system.

And when designing and developing this kind of model, it takes a lot of investment, so they can't help but be hard-headed, so that these ugly models that can be called strange are listed, and after the listing, these models, in addition to poor market performance, also ushered in countless scoldings for them, and even made their corporate brand plummet, becoming synonymous with design failure and ugly models.

But if you have this kind of 3D printing jishu, even if the design of a model fails, but because of your time advantage, you can also have enough time to redesign.

After all, you can design a new car in four months, while others use the traditional way to design a new car in 18 months, which is the advantage of time.

And this is often a temptation that is difficult to resist for a new automobile company.

As soon as he thought of this, Li Yifan was a little enthusiastic, it seems that he still has to make a layout as soon as possible, start to participate in this field, and strive to master this jishu as soon as possible, and apply this jishu to practice.

And if you master this jishu, you can not only use it in the field of automobile manufacturing, but also step out into the field of medical product manufacturing.

Medical product manufacturing! This field is an absolute profiteering industry, how many people in the country need to replace their organs every year?

What a big market this is, and the most important thing is that if you master such a jishu, how many patients will be benefited!

This is an industry that can not only make money, but also have immeasurable merits, and if you do haode, you can also step out of the country, so this jishu must be seized. (To be continued......)
