Chapter 417: One Hour Miracle (2)

"Liquid Crystal No. 3." In Nanming's office, Qingzhong Yang stood in front of the huge French window, looked at the scenery below, and asked in confusion: "Why did you choose this name? I mean, there is Liquid Crystal No. 3, So No. 1 and No. 2? Are they experimental objects?"

"No, I just think it's cool to name it like this..." Nan Ming sat on his office chair and turned around. In fact, when determining the ratio of these cements, Lazy God Technology has carried out countless calculation simulations, so the first trial production was successful, and these calculation simulations, there is no doubt that the Qingda Lazy God that is still expanding It's just a support, mostly thanks to Xiaobai.

Ever since he missed the release of the powered exoskeleton last time, Qingzhong Yang vowed that he would never miss the launch of Lanshen Technology's new products again, no matter what form it was.

Moreover, the reality did not disappoint him. The terrifying construction capabilities demonstrated by Lazy God Technology allowed him to see the fortifications that would rise up instantly on the future battlefield—if there is positional warfare in the future.

Below, Wei Caiming, the boss of Heqing Creation, subconsciously rubbed his palms on his expensive suit to wipe off the sweat from his palms. So far, all the demonstrations have gone smoothly, fortunately.

Because now it's really just Zhang Qinghang and Wang Wanqiang, two guys who didn't know anything about such high-tech things before, directing a group of makeshift people to work on site.

If something happens, the consequences will be disastrous.

However, in a blink of an eye, he became firm again. If such pressure cannot be endured, how will he become the strongest construction and construction machinery company in the world in the future? Moreover, as a company invested by Nanming, if you don't know anything about these things, how can you do it?

So he became firm again and became less nervous, but in this way, the already crappy Putonghua almost completely turned into Qingyang dialect.

"As you can see, we will print a total of 24 such pillars. During this period, let's take a look at 3D printer No. 3." Wei Caiming said.

Under the stage, Wei Ke, who was sitting in the first row, raised his quota by hand. I don’t know who wrote this speech. It is more suitable for a business elite who is full of aura and can speak freely, rather than his own man who can’t even speak Mandarin well. The old man, who also looked full of country in a suit, gestured to Wei Caiming in the audience, but Wei Caiming glared at him.

Stop messing with me!

"Mandarin! Mandarin!" Wei Ke was speechless, no matter how many times he had said it.

He clearly saw the reporters below sniggering.

A huge truck parked nearby drove up. The back of the truck was dragging something similar to a container, but it was bigger than a normal container.

"Printer No. 3 is also a vehicle-mounted printing device. It mainly performs metal printing. Because the laser heating or electron beam used in metal printing are very dangerous, high temperature and high heat will be emitted during the printing process, so the specific printing process is invisible. , the printing process is more similar to printing first and then assembling."

While speaking, Wei Caiming pointed to a reserved point on the ground: "Everyone, please see that we have reserved a fixed base for this position. By the way, the same reinforcement device is also available at the 24 pillars."

Then, with the sound of rattling, the container opened, and a cylinder with a diameter of nearly 3 meters and a length of about three meters stretched out from the container. The cylinder was fixed on a vertical guide rail and fitted there. Reserve the base.

The indicator light on the Yuantong lighted up, and then the entire cylinder slowly rose up, and on the base, the mesh support structure, the bright silver metal bracket was slowly exposed.

This feeling is like the metal bracket is poured out of the cylinder.

"Isn't it directly installed in the cylinder?" Chi Jiafeng asked Wang Gan who was beside him, and almost made Wang Gan laugh.

But Wang Gan didn't need to explain, after a few minutes, the metal bracket standing on the ground was already higher than the cylinder itself, which already explained everything.

"Brother, just now I heard Mr. Wei say that 3D metal printing uses lasers and electron beams, both of which are very dangerous. So what kind of technology is used for this 3D printing? Or is it a mixture of the two?"

Wang Gan smiled and said nothing. Chi Jiafeng raised his eyebrows, knowing that it was inconvenient to answer, so he crossed this question out of his notebook.

"Actually, neither." Upstairs, in Nan Ming's office, Nan Ming was also answering Qing Zhongyang's question.

Before coming here, Qingzhong Yang also did enough homework, and even specially invited technical experts in the army to give him a special lecture, and he organized many officers around him to listen.

"Neither?" Qingzhong Yang wondered.

"Although we are quite good at lasers, and electron beam technology is not too difficult, we actually used another method of kinetic energy metallization." Nan Ming said, "Through a magnetic field, the ultrafine metal particles are directly accelerated to 1-6 Mach, when the metal hits, it will produce different plastic deformations according to the speed, resulting in different material internal stresses, this 3D printing technology is almost perfect."

The so-called Mach is the speed of sound, and metal particles accelerated to Mach 6 are 6 times the speed of sound. This speed is very dangerous, so it must be covered. It cannot be open or semi-open like other printing methods, but a cylindrical printing chamber.

For a long time, the gap between metal 3D printing and castings mainly lies in the fact that ordinary castings can be punched by stamping machines during the processing process to improve their material properties, and this can be perfectly simulated by adjusting the speed of metal particles. Yes, but what kind of speed and angle are required for the specific properties of the metal, and a large amount of data is required.

This method can greatly reduce the energy loss in the 3D printing process. In fact, if the speed is fast enough, when it hits the printing surface, the extremely high kinetic energy will be converted into heat energy, and the metal particles will be melted instantly by themselves. It is extremely robust. And this method can create a variety of fusions and alloys, not just for printing metals. The war-damaged drone packaging box of Lazy Technology uses this kind of metal. When different materials are sprayed out , requires fine adjustments and countless calculation simulations. Of course, this process also relies on Xiaobai's wisdom and authority.

While speaking, the support with a mesh structure was already more than ten meters high, and the guide rail had been stretched to the extreme, and then the metal cylinder withdrew from the support. After exiting, everyone found that there was a small L-shaped turning structure.

At the top of the guide rail, the metal cylinder printing chamber was flipped 90 degrees to become horizontal, and then a relatively short section of the L-shaped turning structure was swallowed into it, and then the metal bracket began to continue to extend.

"Is this the so-called splicing after printing?" Chi Jiafeng wanted to laugh a little cry, young man, why are you so modest, can this also be called splicing?

"Technically and theoretically, this is indeed a splicing." Wang Qiandao said that they are scientists, and scientists must seek truth from facts.

Actually, while they were talking, Printer No. 1 wasn't idle either. It was moving around, marking places reserved on the ground, and printing all sorts of things, including fancy fences, concrete benches, and all sorts of things. The strange sculpture, and the No. 3 printer, the horizontal bracket printed in mid-air also showed a slight arc shape, and other brackets stretched out from the truck to support the printed bracket, at a distance of about three At a distance of more than ten meters, the cylindrical printing chamber exits again, and at the end of the bracket, there is a T-shaped reserved interface.

Then, under the T-shape, a vertical support bracket was printed, and a complete air bridge was formed.

Many people are staring at the No. 3 printer, because they are curious about what to do after the printing chamber reaches the bottom, and how to exit from the completely closed zigzag structure.

Then I saw the printing chamber split open with a click, splitting into two halves, revealing the densely packed print nozzles inside, shaped like crab legs, Chi Jiafeng took the opportunity to snap a picture, Wang Gan shrugged with a smile, and didn't stop it.

"This is, planning to enclose the entire research institute?" Chi Jiafeng asked, looking at the various gazebos, sculptures and flower bed fences, and then at the ten-meter-high aerial bridge, Chi Jiafeng suddenly felt that he knew Lazy Technology is going to print something. (To be continued.)
