Doomsday Bunker Upgrade

A steel structure with a height of more than thirty meters and a length of more than fifty meters cannot be made. This is an incredible thing for the Yan Kingdom.

If larger and more demanding metal components were made before the disaster, the people of the Yan Kingdom would never have been limited by conventions to their imagination.

However, it is indeed difficult to manufacture such a steel component now that a large number of industrial production capacity in the country has been affected, and it is indeed impossible to do it without sufficient industrial base.

Of course, there are solutions. As a major country in infrastructure construction, Yan Kingdom certainly has alternatives.

Of course, the simplest method is to change the design and replace the current support column scheme with more columns and support beams that can be processed or simply poured out of reinforced concrete, which can also complete the construction of the dome, but the corresponding That is, more support columns need to be added inside the dome.

Such a scheme is more practical, but more support columns inside the corresponding dome will have an impact on the interior space. Although it has little impact under reasonable planning, it is not as good as a transparent overall structure.

The second method is to use the welding process to manufacture the components of the support column in sections, and then assemble them by welding.

Such a method can naturally meet the requirements. The welding process of Yan Guo can already meet such requirements, but as a whole, segmented welding will still have an impact on the support strength, which is not as strong as integral molding.

Both schemes can play an alternative role, but the first scheme affects the space utilization, and the second scheme affects the structural strength. The design team could not make a choice for a while, so they could only send both schemes to Chen Xin, so that the Party A to make a choice.

The design team did not want to dump the blame, and they also saved the idea to see if Chen Xin could come up with other solutions here.

Chen Xin Is there a solution here?

The answer is of course yes.

"There are two solutions to this problem, one is that I make a machine that can process steel parts of this size to process what is needed, and the other is to use 3D printing technology to print what is needed." Chen Xin didn't think the problem was too difficult to solve, and also gave two solutions.

"What are the characteristics of these two schemes? Is the structure strong enough for 3D printing?" The engineers and technicians who came to submit the scheme to Chen Xin asked Chen Xin. Although 3D printing technology has developed rapidly in recent years, it still has enough strength. No one can claim that their technology can be used to print such large metal structures.

And let’s not take a step back, even if such a large metal structure can be printed, how can 3D printing ensure that the printed components can meet the requirements in terms of strength?

As for Chen Xin making a machine that can process components of this size, the engineers and technicians have no doubts that Chen Xin can do it.

"Making a machine to make a component is lackluster. Except for the upgrading of processing accuracy and processing technology, it is basically the same as the normal processing of such a component. It is nothing more than using my machine. It may consume less energy and process it. The quality of the components is better." Chen Xin explained briefly, and did not explain more about the first plan he proposed.

However, as for 3D printing, he said with great interest: "As for 3D printing, this is basically not much different from the existing technology on the market. It also sprays the material through a nozzle, and then melts the material through laser sintering. resolidifies, resulting in a stable structure."

Having said that, Chen Xin paused for a while, and after the engineers and technicians had digested what he said, he continued: "However, the laser sintering technology I used is more effective than the ones currently on the market, and the sintered materials are in Structural strength is also more sturdy and durable.

In addition, the technology I provide does not require a sealed environment to strictly control air flow and air humidity, and can be applied to the printing and manufacturing of large-scale structures or buildings. It is also possible to print out the alloy. "

"Alloys can be printed?" The engineers and technicians had surprised expressions on their faces.

It's not enough to shock engineers if it's just printing large metal components, but the ability to print alloys directly from a single metal powder mix is ​​a bit incredible.

Making alloys is more than just mixing metals together. Different properties require different treatments.

It's like the stainless steel tableware in your home and the shipbuilding steel for warships are both nickel-chromium alloys, but there is a huge difference in performance between the two.

But this is nothing to Chen Xin. Even if he wants to, it is no problem to build a molecular metallurgical furnace. He directly decomposes various materials from the molecular level, and then rearranges and combines the molecules as required to obtain his own The required materials are also available.

Of course, the metallurgical technology at this level is too exaggerated, and Chen Xin is not ready to make it for the time being.

Just the current 3D printer that can print alloys is enough.

"It's hard for me to explain the specific principles and techniques to you, but you only need to know that I can do this." Chen Xin is still a pair of "I just do things, you can study the principles yourself." However, he also explained: "I can make a small one first, and you can test it and see the effect."

"That's the best!" The engineers and technicians couldn't say more excitedly at this time, and they just looked forward to the 3D printer that Chen Xin promised to print alloys.

If Chen Xin can really achieve this, even if it is just printing some simple alloys, it will have extraordinary significance in practical application.

Chen Xin naturally also saw the excitement of the engineers and technicians in front of him. For Chen Xin, he had seen too many scenes where someone was excited because of his own words, and he had never responded to it, so He just nodded indifferently and said, "Then I'll make a small prototype for you first, and you can experiment with it. After confirming the effect, let's talk about the follow-up construction plan."

"Okay, Academician Chen!" The engineering and technical personnel agreed, and finally suppressed the excitement in their hearts.

As for the change in the construction plan, this is of course what it should mean. If it is a traditional construction plan, it is necessary to build a shelf and install and weld it by workers bit by bit.

But if you use 3D printing, you can completely build high-rise buildings on the ground. You don't need so many construction workers. You only need to let the 3D printer print the main structure by itself, and then the workers will handle the follow-up work.

The two are quite different in terms of engineering volume and construction difficulty.

I haven't found out whether 3D printing can print alloys. If there is such a technology, you can be a parallel world.
