"Lao Dou, follow me!" Under the leadership of and Walli, Chen Xin entered the equipment manufacturing workshop of the Longshou Mountain underground base for the first time.

The equipment manufacturing workshop is even more magnificent than the machining workshop in Cybertron Machinery Company on the ground, covering an area of nearly 1,000 square meters, with a total of three parts, divided into two floors, each 20 meters.

Such a huge space is now occupied by all kinds of mechanical structures, even if it has been mixed with steel hammers for so long, Chen Xin can't tell what these devices are used for.

However, he can see that the entire equipment manufacturing workshop can be divided into three parts.

The first part is a set of 20 tons per day metal battery production line, has entered the trial operation state, but due to the limitation of raw materials and electricity, now about two tons of metal batteries can be produced per day, Chen Xin has prepared a 125 cubic meters of metal batteries for these metal batteries, which can store nearly 800 tons of metal batteries, according to the energy density of 20 kilowatt hours / kilogram, the backup power supply of the underground base of Longshou Mountain can store 16 million kilowatt hours of electricity.

The second part is a fully automated 3D printing workshop, which occupies the upper and lower floors of the equipment workshop, which will become the equipment manufacturing center of the war.

The last part is a set of small wafer production lines and laser etching equipment, which will become the intelligent core of these equipment.

In addition, there are various cranes, conveyor belts, and auxiliary industrial machines, Chen Xin stood on the corridor, looking at the huge space under his feet, imagining when they were running at full speed. What a magnificent scene it will be.

But in order for these devices to work, Chen Xin must first get a controllable fusion reactor out of the box.

This time, Chen Xin didn't plan to let go into battle in person, he wanted to test the manufacturing strength of 3D printing equipment.

Although the steel-reinforced controllable fusion reactor has been miniaturized, it is still a large cylinder with a diameter of six meters and a height of five meters.

Such a big guy, human beings have not yet had a 3D printing equipment to build it, not to mention that it involves many top materials and high-precision parts.

But this 3D printer made of steel is different, it is nearly 40 meters high and covers an area of more than 200 square meters. Basically, the upper and lower floors of the equipment manufacturing workshop are occupied.

with this printer. It can print out equipment with a size of 50 x 50 x 20 meters, and the fusion reactor with a steel hammer design is really a small guy compared to it.

Chen Xin looked at this huge machine with bright eyes, as long as there were enough materials. He could even print out the Dream Spaceplane. What a great power this is!

"Old beans. It's time to go!"

Chen Xin nodded, walked straight to the console of this giant 3D printer, and took out a USB flash drive from his pocket. Plug into the USB port.

The USB flash drive contained a 3D detailed drawing of the fusion reactor designed by the steel hammer and the printing program, Chen Xin clicked a few times on the operating table under the guidance of the steel hammer, and soon, the machine made a slight roar, and Chen Xin could feel the bridge under his feet shaking slightly.

The metal and non-metal raw materials in the previous warehouse were crushed powders, which were injected into the 3D printer through pipes that were not visible to Chen Xin.

Soon, the 3D printer's printhead descends onto the workbench under the manipulation of a superconducting motor.

In fact, the entire 3D printer has 60 printheads, but this time to print a controlled nuclear fusion reactor, only ten of them were used for the time being.

The 3D printer is made of steel and hammer using laser powder sintering technology, which is not complicated, in fact, China has successfully used titanium alloy laser powder sintering to form large aircraft structural parts not long ago.

The laser powder sintering of aircraft components produces extremely fine-grained blanks (due to this characteristic, the turbine disc and blades of the engine cannot be manufactured using this technology), and then it is very troublesome to do cutting to ensure accuracy.

However, this one-time 3D printing of the fusion reactor requires several orders of magnitude of higher precision and standards than the current technology of mankind.

Although Chen Xin doesn't understand the Tao of this, he also understands the difficulty of it.

At the moment when the 3D printing printhead was about to make contact with the workbench below, a dazzling light suddenly appeared between the workbench and the printhead.

This is an extremely hot laser!

At this moment, a surprising scene appeared, after the nozzle, the laser did not leave any traces on the black workbench.

"What's going on?"

Chen Xin was dumbfounded and asked, "Steel hammer, why is there nothing on it!"

shook his head and said, "No! Old Bean, take a closer look!"

Chen Xin narrowed his eyes, and soon noticed something strange on the workbench. It can't be said that there is no at all, when the nozzle moves rapidly, Chen Xin found that there is a layer of almost imperceptible reflection in the area where the laser nozzle passes, which makes the original pitch-black workbench slightly different from the original.

explained: "Lao Dou, this kind of nozzle is sprayed layer by layer, and now the thickness of the first layer is about 0.01 microns, because the coating is too thin, so we can't see it for the time being." ”

Chen Xin quickly mentally calculated, each layer is 0.01 microns, so one micron needs to be sprayed 100 times, 1 millimeter needs to be sprayed 100,000 times, what about six meters, then six times?

Even if ten printheads print at the same time, it takes 10 seconds to apply each layer, how long will it take?

Gangyi seemed to see Chen Xin's thoughts, and continued to explain: "But you don't have to worry about Lao Dou, it's only the first layer now, we have to maintain the accuracy of the shell, so the thickness of each layer is very small, as long as it accumulates to 10 microns, we can spray at a speed of 0.1 mm per layer, so that the speed will be faster!"

Of course, the speed of the steel hammer is compared to the previous speed of 0.01 microns per layer, and even if the speed is subsequently accelerated, it will take at least 20 days to print the fusion reactor in its entirety.

Chen Xin thought for a while and said, "Steel hammer, then there is no problem with its structural strength, right?"

After all, this fusion reactor is filled with a small sun, even if Chen Xin knows that if it explodes, it will definitely not be able to stop it with this shell, but it is better to have a higher structural strength and give people a little comfort!

Gangyi laughed and said: "Old Dou, don't worry, you also know that the power generation principle of our fusion reactor is not to convert thermal energy into mechanical energy to generate electricity, but to directly generate electricity through the photoelectric effect, so it will run very quietly at that time, as long as the magnetic field strength is enough, then there will be no problems with this fusion reactor!"

Chen Xin nodded and said, "That's good!" (to be continued......)
