Vol 3 Chapter 219 3D printing

On the moon, under the special environment, humans cannot actually be the main force of construction.

Although the low-gravity environment has little effect on humans, the vacuum environment without air requires carbon-based organisms that want to move in this environment to wear heavy spacesuits.

Even if Yang Qing made a light-weight spacesuit, without the transformed bodies like him and Zhao Yuxi, it would be difficult to use it freely.

Therefore, it is certain that the construction of the moon will be dominated by robots.

The human settlements on the moon in the future should be a closed system similar to the moon palace bases.

It’s like small cities connected by vacuum pipes. On Blue Star, it is almost impossible to realize the vacuum pipe transportation with a speed of 4,000 kilometers per hour. Here, it seems possible to realize it.

In fact, according to Yang Qing’s transformation plan, he originally planned to increase the gravity and protective cover of the moon according to the method of transforming the small plane in the prehistoric period, so that the surface of the moon will be filled with air and realize an environment that is almost the same as that of the blue star.

But looking at it now, it seems that it is more realistic to keep the moon in a vacuum state, at least it is more convenient to smelt various minerals.

The elements of the moon are similar to the crust of the blue star. A metal smelting furnace can get oxygen, nitrogen, chlorine, carbon dioxide and other gases. Naturally, potassium, sodium, aluminum, iron, copper and other metals are indispensable.

Although in the environment of the moon, the separated gases and metal elements all contain a large amount of radioactive isotopes, but after separating these radioactive isotopes, what remains is still a very beneficial supplement, especially those oxygen And nitrogen, even carbon dioxide, is an excellent fertilizer.

With the official work of the metal smelting furnace, it was dug from ilmenite and rutile ore. After cutting, it became the smallest possible pieces and was directly filled into the smelting furnace.

It’s not that Yang Qing doesn’t plan to crush these minerals into mineral powder like Blue Star, but it contains a lot of elemental iron.

Although such elemental iron is produced in different environments, there must be countless impurities, different hardness, and various indicators are in a mess, but it is metal after all, with a certain strength and ductility. They crumble, so the next best thing is to cut them into small pieces.

Anyway, the heating method of the flame talisman is somewhat similar to the heating of the intermediate frequency furnace, which starts to heat inside the metal, so the size of the material has little effect on their melting.

However, it is naturally not as fast as the melting speed of ore powder, but Yang Qing is using a flame talisman, which is a conforming talisman. The more superimposed, the higher the temperature.

The most important thing is that this thing is superimposed to the extreme, and can even reach a high temperature of hundreds of millions of degrees, which is perfect for melting ore.

If you don’t consider those compounds with lower boiling points, it can raise the temperature to more than five thousand degrees at once.

There is not one such metal refining furnace, but dozens or hundreds of them. The raw ore from the mine is excavated, then transported by truck, sent to it through a conveyor belt, and sorted into pure aluminum. Iron, copper and most importantly titanium.

Although the metal particles condensed by the steam are also a large pile, the purity is also extremely amazing, but because of the simple condensation, it presents a sponge shape.

But the shape doesn’t matter much, the ratio is important.

70% iron, 20% titanium, and 10% aluminum are fused together according to the mass ratio to form a brand new titanium-iron-aluminum alloy.

This kind of alloy can withstand low temperatures close to absolute zero without greatly changing its strength. Only five hundred degrees above zero will cause softening. Compared with ordinary pure titanium alloys, it is stronger.

Probably the only difference between it and ordinary titanium alloy is that it is heavier and not suitable as an aircraft material.

Alloy materials are produced and immediately enter the forming shop.

The red-hot alloy material will not only not oxidize in a vacuum environment, but can also maintain a high temperature state for a long time, so that it can be processed in the next step calmly and turned into various profiles.

Of course, the initial application of these alloy materials is still reflected in robots.

Although the number of robots existing in the entire base has exceeded 2,000, this number is still too far away for the entire moon. Xiao Ai plans to increase the number of robots to more than 10,000 during this moonlit night.

Such a quantity can barely support the next expansion of the lunar base, which is to connect the area of ​​10,000 square kilometers into one piece and become the first city built by humans on the moon.

The Moon Base must be opened. This is a definite thing, but there are too many secrets in the Moon Palace Base, and it must not be released in front of everyone without reservation.

So Yang Qing plans to build various buildings outside the Moon Palace to serve as residential areas, hotels, etc. In the future, he may also provide some laboratories for countries and scientists on the blue star.

All of this depends on the metal refining furnace, the extracted metal, and the alloy frame made of it.

According to the situation on the moon, metal container buildings are the most convenient and easiest to build. Of course, in the future, large-span steel structure buildings may also appear in response to demand.

Anyway, in the short term, unless it is digging holes on the moon, there will never be reinforced concrete.

The alternate use of metal wool, aerosol, and various thermal insulation materials can simplify the most troublesome thermal insulation problem of this type of building.

In fact, on the moon, in addition to the need to isolate the high temperature of more than 100 degrees brought by direct sunlight, staying inside the building does not have to worry about the low temperature of more than 100 degrees during moonlit nights.

Because the vacuum environment on the lunar surface ~www.readmtl.com~ is like a thermos, so that the heat inside cannot be dissipated at all.

So in a vacuum, cooling is far more urgent than heating up.

The metal solution, in the form of 3D printing, is used to print the parts of the robot with a droplet size of 0.01 mm in diameter under the control of Xiao Ai.

Although it is in a vacuum, with the help of the frost circle, the droplets will solidify in a few microseconds, quickly printing out the parts of the robot one by one.

Dozens of 3D printers are lined up, linked to the metal melting furnace, and soon you can see pieces of silver-white bodies, formed from the inside, and then pushed out, sent to the conveyor belt, and assembled by countless robots.

Although up to now, the base has not refined silicon to make silicon chips, but Xiao Ai has brought millions of standard chaotic architecture chips from the moon, which can serve as the brains of robots.

There are more reserves of artificial muscles, at least for Xiao Ai to manufacture 50,000 robots.
