"Of course, this is only one aspect." Mr. Cheng continued: "The greater significance of this exploration is to prepare for the follow-up lunar scientific research station project. Everyone knows that the surface environment of the moon is relatively harsh, and the surface lunar soil is relatively fluffy. , even if the gravitational force on the moon is small, if you want to build houses and other facilities on it, you must explore the lower layers of the lunar soil to find relatively stable sedimentary layers or rock layers, so that the built houses will be more stable.

The same is true for the houses we build on the earth. Before building a building, we also need to explore the foundation of the building, and then evaluate whether the geological environment is suitable for building the building, and which foundation method can be used to make the building more stable. and many more. "

Chief Engineer Cheng's words fell, and Chief Engineer Wang on the side also added: "Similarly, this time on this 'Wangshu No. 2' intelligent lunar surface detection experimental vehicle, a construction 3D printer was used. Let's conduct some 3D printing experiments of lunar science station building materials.

If this experiment is successful, then in the future we will build scientific research stations and even future lunar cities on the moon, then we can get materials on the spot, no need to transport them from the earth, which can save us a lot of money and money. resources, it can also save a lot of time, and it can make it easy for us to obtain a shelter on the moon that can survive for a long time. "

Hearing Mr. Wang's words, the host's eyes lit up and he immediately asked, "President Wang, Mr. Cheng, now netizens are curious about this architectural 3D printer. Can you two give us a detailed introduction?"

Hearing the host's question, Mr. Wang smiled and nodded and introduced: "It's actually a 3D printer, but the material it uses is moon soil and a small amount of additives, and what it prints is a kind of semi-finished 3D printer. Glazed material for glass.

In this respect, it is a bit like the ancient glazed brick glazed tile. Of course, the strength structure is stronger than the glazed brick glazed tile. "

It's actually sand. Mr. Cheng said with a smile: "I saw this device when I visited Mr. Wang and the others. It is very ingenious. It can melt sand into a glass solution, and then print it out through the nozzle of the printer, condensing it into the desired shape and structure. Materials.Full Content

This kind of printed material is very strong. The technicians over there tested it for us. They directly used a sledgehammer to smash it hard, and only lost some powder. The structure is still intact and has a higher structural strength than concrete. "

"Then Mr. Wang, Mr. Cheng, I have a non-professional question. Since this 3D printer has been tested on the earth, and I heard from you that the test results are excellent, why bother to send it to the moon to test again. ." The host glanced at the tablet in front of him, and then asked the two experts.

Mr. Wang heard this question and explained with a smile: "Because the composition of lunar soil is relatively complex, it contains many other elements, which are very different from the sand and soil on the earth. Moreover, in the test on earth, , This 3D printer cannot use soil to print, it still has certain requirements for materials. It is best to choose relatively pure quartz sand, such as silica, if it is doped with some other materials, it will directly affect The performance of this 3D printer and the strength of the printed materials will also be greatly affected.

On Earth, we can directly use this 3D printer to print very pure glass, but not on the moon, unless we have a filtering device that can filter the lunar soil and filter out the required materials.

So this 3D printer is specially designed for the lunar soil, and the experimental team will also conduct relevant experimental tests on the components of the lunar soil, so as to test out an ideal formula for subsequent transportation. Larger 3D printers prepare for construction of a lunar science station. "

"Mr. Cheng, some netizens put forward that since this technology is so complicated, why should we use lunar soil instead of the mineral resources on the moon, such as iron ore, manganese ore, aluminum ore, copper ore, etc., which are in the lunar soil? The content of the medium is also very rich. And the built facilities are stronger." The host glanced at the tablet next to him, then smiled and asked a new question.

That's a good question, and our scientists have the same idea, but it should be decades away. Mr. Cheng replied with a smile: "Although the minerals you listed have good reserves on the moon, the lunar mining technology is relatively difficult and expensive. Let's not talk about the other tools and equipment used for mining. How to transport it from the moon. Even if it is transported, the cost is undoubtedly huge.

The reason why Haoyu Aerospace is experimenting with this 3D printing technology on the moon is to use the resources on the moon to minimize the construction cost of the lunar scientific research station according to local conditions.

Therefore, at this stage, scientists are still more inclined to use this kind of cheaper and simpler lunar soil materials to build early lunar scientific research stations or shelters, which will be used for early personnel residency and survival shelters. "

As soon as Mr. Cheng's words fell, Mr. Wang went on to say: "Actually, scientists have come up with many plans for using lunar soil to build houses or shelters on the moon.

Some scientists have proposed to use our traditional building techniques to build houses by beating the moon soil, so that enough space can be built according to local conditions for the resident personnel.

It is also proposed to use lunar soil and water to make brick embryos, and then use solar power to burn bricks, and then build houses. There are also proposals to transport cement and other mixed materials from the earth, and then mix with the lunar soil, pour concrete, and so on.

The solution proposed by Haoyu Technology to use lunar soil for 3D printing to build houses is very ideal in terms of technical feasibility, economy, and the strength and reliability of the printed building structure. It should be said that it is a A set of highly feasible optimal solutions.

To be honest, I was somewhat looking forward to the results of this experiment. If it can be successful, it means that our country has mastered a key technology that can build permanent buildings on the moon and realize long-term personnel residency.

As a result, our country can build an objective-scale scientific experiment center on the moon with very little capital, laying a solid foundation for subsequent deep exploration and development of the moon. "

Some people died, but not completely...

After the endless coma, Shi Yu suddenly got up from the bed. To see the latest chapter content, please refer to the latest chapter content. The website has not updated the latest chapter content, and the iRead app has updated the latest chapter content.

He took a deep breath of fresh air and his chest trembled.

Confused, puzzled, all kinds of emotions flooded into my heart.

where is this?

Afterwards, Shi Yu looked around subconsciously, and then became even more at a loss.

A single dorm?

Even if he was rescued successfully, he should be in the ward now.

And my own body... how can I not hurt at all.

With doubts, Shi Yu's eyes swept across the room quickly, and finally his eyes stopped on a mirror by the bedside.

The mirror showed his current appearance, about seventeen or eighteen years old, and his appearance was very handsome.

The problem is, it's not him!

My previous self was a handsome young man in his twenties, who had been working for a while.

And now, no matter how you look at this appearance, it is only the age of a high school student...

This change left Shi Yu stunned for a long time.

Don't tell him that the operation was a success...

The body and appearance have changed. This is not a matter of surgery or not at all, but an immortal technique.

He turned into a completely different person!

Could it be... did you pass through by yourself?

In addition to the mirror at the head of the bed, which was clearly placed in a bad feng shui position, Shi Yu also found three books beside him.

When Shi Yu picked it up and took a look, the title of the book instantly silenced him.

"Necessary Animal Breeding Manual for Novice Breeders"

"Postpartum Care of Pets"

"Evaluation Guide for Alien Beast Ears"

Shi Yu: ? ? ?

The names of the first two books are quite normal~www.readwn.com~ What's the matter with the last one?

"cough."

Shi Yu's eyes narrowed and he stretched out his hand, but his arm froze soon after.

Just as he was about to open the third book to see what it was, his brain stabbed violently, and a flood of memories flooded in.

Icefield City.
