Rebirth 2002: Nano Life

After the two sessions this year, the country proposed to carry out cross-industry alliances between 3D printing and important sub-sectors such as automobiles, aerospace, and biomedicine, and break through a number of special materials for additive manufacturing to meet the needs of industry development. This is also what Chen Yizhe is happy to see.

As the top of the world's richest list, a world celebrity, and a national idol, Chen Yizhe did not enter the National People's Congress and the Chinese People's Political Consultative Conference.

The members of the CPPCC are not elected, but recommended. Therefore, there are many senior intellectuals, entrepreneurs, and experts in various industries in the members of the CPPCC. Many rich people are members of the CPPCC. In fact, as early as 2008, the Guangdong Province recommended him to be a member of the Guangdong Provincial Committee of the Chinese People's Political Consultative Conference, but Chen Yizhe eventually refused.

The deputies to the National People's Congress are elected by election. All citizens of the People's Republic of China who have reached the age of 18, regardless of ethnicity, race, gender, occupation, family background, religious belief, education level, property status, residence period, have the right to vote and right to be elected. It sounds fair, but I believe that many people have never used this right to vote and stand for election, the operation of the National People's Congress.

Chen Yizhe has only attended once in his last life for more than 30 years, and it was at the university meeting. At that time, the counselor listed two candidates for the National People's Congress, and asked Chen Yizhe's classmates to choose them. One of the students wrote his name, and the counselor told him to get out.

In view of this, Chen Yizhe once said on some occasions that he has no interest in the two sessions, because he cannot represent others, the only one who can represent is himself.

…

July 23.

Guancheng Guanlan.

Chen Yizhe took 270 to visit the smart workshop located here. In addition to watching the fully intelligent production process of the car, 270 focused on Xia Meng's 3D printing technology.

When 270 watched Xia Meng's large-scale 3D printer print out a large square plate, 10 minutes after the finished product, it suddenly turned into the shape of a car shell, and he was stunned.

"What exactly is going on here?" 270 asked Chen Yizhe.

Chen Yizhe said with a smile, "This is the 4D printing concept proposed by Xia Meng last year!"

"4D printing? Time?" 270 responded very quickly and put forward the key point.

"bingo!" Chen Yizhe snapped his fingers, "3-dimensional space plus time is the so-called 4-dimension, and the same concept of 3-printing plus time is 4D printing. That is, the printed materials can change over time. In exchange, the printed product can interact with water, air, and temperature to automatically deform."

According to Xia Meng's design, after the material is printed, it can be folded into a corresponding shape just like the scene seen by 270, so it may be used in daily commodities, biomedicine, aerospace industry and other fields.

"It's not the most amazing thing. I'll give you a special gift when I get back to the office!" Chen Yizhe laughed.

"Really?" 270 was surprised. If Chen Yizhe could say it was special, then there must be something different.

"Actually, it's not for you, it's for your sister-in-law!" Chen Yizhe said with a smile.

"Then I want to thank you on behalf of Liang Hong, but listening to you say that, it arouses my curiosity. Can you tell me what it is?" 270 asked curiously.

"Anyway, I will tell you when the gift is given to you. In fact, this gift is just a dress." Chen Yizhe said.

"dress?"

"It's a 4D printed dress, to be exact, hundreds of interlocking 3D printed 'parts' are 'woven' into a dress to guarantee its softness and flexibility, for a total of 4120' parts ' is held together by 4,709 'links'. And the dress basically changes shape every three or four days."

"Are you helping me save money?" 270 continued after joking, "But this 3D printed product can be deformed, so it must be related to the material, right?"

Chen Yizhe nodded, "The material used in the existing 4D printing is a memory polymer material, which is a new material studied by Xia Meng, a composite material composed of polyurethane and graphene nanometers, which is produced by external forces. After deformation, unlike ordinary sponges that can be restored immediately, they can be restored to their original shape within a certain period of time without residual deformation through the design of some microscopic electronics, so that the objects they build are actively produced like machines, while It's not about setting the object and then making it'."

"That is to say, in the future, when many items are not in use, they can be turned into the size of a piece of paper, and when they are needed, they can be deformed?" 270 asked.

"You are quite imaginative, but what you said is very likely to be realized. In fact, some of Xia Meng's 4D printed products have already entered the commercial market." Chen Yizhe said, "For example, the 'limbs' that will develop and 'Five senses' and so on, these 4D printed medical products of Xia Meng have already been put on the shelves in Xia Meng Private Hospital in Wenchuan, but unlike ordinary 3D printed products, the temporary charges for these products are very high."

"Wait, let me ask first, what is the price of the dress you are going to give to Liang Hong?" 270 asked suddenly.

"About 250,000!" Chen Yizhe told the truth.

"Too precious!" 270 said.

"It's okay, I don't mind if you want to buy it with money!" Chen Yizhe said.

"Why do you feel like you are selling?" 270 said speechlessly.

"Everyone I know has given one set, so don't let your mother-in-law!" Chen Yizhe laughed.

"Actually, compared with clothes, the cost of 3D printing human organs is slightly higher due to the implanted control chip. Of course, it also depends on the size of the printed organs!" Chen Yizhe laughed.

…

Due to 270's journey planning, UU reading www.uukanshu. com is going to drive through a region in the Middle East where the economy is seriously backward after the war. Therefore, this time, Chen Yizhe did not unrealistically let the 270 drive the pure electric version of the dream. The second is to create a parallel hybrid for this purpose. Version.

Pure electric represents the future, and hybrid power is like an excess, but for Xia Meng, the future has been developed, but for this excess version, it is a bit difficult. The main reason is that Xia Meng lacked the technology of the internal engine system.

But after all, there is Chen Yizhe. At present, there are some ideas in the design. The first version of the parallel hybrid has come out. Generally speaking, the intelligent switching Xia Meng has done well, but the engine is still not satisfactory, and Xia Meng is still needed. The team continues to develop. But for the 270, Xia Meng can achieve this level in a short period of time, and he is also very informative about Xia Meng's next successful development of a mature hybrid version of the Ix1.

August 1st, Army Day.

On this day, Chen Yizhe, who was playing with the children at Pengcheng's house, received a satellite phone call from Song Feier.

"Half an hour ago, an Australian warship broke into the waters of Dream Valley!" Song Feier said nervously on the phone.
