"Liquid Crystal No. 3. In Nanming's office, Qingzhong Yang stood in front of the huge floor-to-ceiling window, looking at the scenery below, and wondered, "Why did you come up with that name? I mean, there is liquid crystal No. 3, so are No. 1 and No. 2 the test samples?"

"No, I just think it's cool to name it like this......" Nan Ming sat on his office chair and spun around. In fact, when determining the ratio of these cements, Lazy God Technology has carried out countless calculations and simulations, so the first trial production was successful, and these calculations and simulations, there is no doubt that the Qingda Lazy God that is still expanding is just an auxiliary, and most of them are the credit of Xiaobai.

Since the last time he missed the release of the powered exoskeleton, Qingzhong Yang has vowed that he will never miss the new product launch of Lazy God Technology again, no matter what form it takes.

Moreover, the reality did not disappoint him, and the terrifying construction ability shown by Lazy God Technology allowed him to see the fortifications that rose from the ground in an instant on the future battlefield - if there was a positional war in the future.

Below, Wei Caiming, the boss of Heqing Creation, subconsciously rubbed his palms on the expensive suit and wiped the sweat off his palms.

Because now it's really just Zhang Qinghang and Wang Wanqiang, two guys who didn't know anything about this kind of high-tech stuff before, are directing a group of temporary crammers to carry out on-site construction.

If something happens, the consequences are unimaginable.

However, in the blink of an eye, he became firm again, if such pressure could not be withheld, then how could it become the strongest construction and construction machinery company in the world in the future? Moreover, as a company invested by Nanming, if he didn't know anything about these things, how could he do it?

So he was firm again, a little less nervous. But in this way, the already lame Mandarin almost became the Qingyang dialect completely.

"As you can see, we will print a total of 24 such columns, and during this time, let's take a look at the 3D printer No. 3. Wei Cai famous.

Offstage. Wei Ke, who was sitting in the first row, didn't know who wrote this speech, it was more suitable for the business elite who was full of aura and swaying freely, rather than his own father, who couldn't even speak Mandarin well and looked full of local flavor when he wore a suit.

Don't make trouble for Lao Tzu!

"Mandarin! Mandarin!" Wei Ke was speechless, how many times had he said it.

He clearly saw the reporters below snickering.

A huge truck parked next to it drove up. In the back of the truck, a container-like thing was being towed. It's just a little bigger than a regular shipping container.

"The No. 3 printer is also a kind of vehicle-mounted printing equipment, which mainly carries out metal printing, because the laser heating or electron beam used in metal printing is very dangerous, and high temperature and high heat will be released during the printing process, so the specific printing process is invisible, and the printing process is more similar to printing first and then assembling. ”

As he spoke, Wei Caiming pointed to a reserved point on the ground: "Everyone, please look, we have reserved a fixed base in this position." By the way, the same reinforcements were also available at 24 columns. ”

And then. With the sound of Titicaca, the container opened, and a cylinder with a diameter of nearly 3 meters and a length of about 3 meters stretched out of the container, which was fixed on a vertical guide rail and set on the reserved base.

The indicator light on the circular light is on. Then the entire cylinder slowly rises, and on the base, the mesh support structure, the bright silver metal bracket is slowly revealed.

It felt like the metal stand had been poured out of a cylinder.

"It's not just in a cylinder, is it? Chi Jiafeng asked Wang Qian beside him. almost made Wang Qian laugh.

However, Wang Qian didn't need to explain, a few minutes later, the metal support erected on the ground was already taller than the cylinder itself, which already explained everything.

"Brother Qian, just now I heard Mr. Wei say that 3D metal printing uses laser and electron beams, which are very dangerous, so what kind of technology is used in this kind of 3D printing?

Wang Qian smiled and didn't speak, Chi Jiafeng raised his eyebrows, knowing that it was inconvenient to answer, so he crossed this question from his notebook.

"Not really. Upstairs, in Nan Ming's office, Nan Ming was also answering Qingzhong Yang's question.

Before coming here, Qingzhong Yang also did his homework, and even specially invited technical experts in the army to help him give 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 difficult, we actually use another method of kinetic metallization. "Nan Ming Dao," through the magnetic field, the ultra-fine metal particles are directly accelerated to Mach 1-6, and when the metal is impacted, it will produce different plastic deformations according to the speed, resulting in different internal stresses of the material, this 3D printing technology is almost perfect. ”

The so-called Mach is the speed of sound, and the metal particles that accelerate to Mach 6 are 6 times the speed of sound. This speed is very dangerous, so it must be shrouded, not open or semi-open, as is the case with other printing methods, but with a cylindrical print cartridge.

For a long time, the gap between metal 3D printing and castings mainly lies in the fact that ordinary castings can be stamped by a press in the processing process to improve their own material properties, and this, by adjusting the speed of metal particles, can actually be perfectly simulated, but what kind of metal properties need what speed and angle, still need a large amount of data.

In fact, if the speed is fast enough, when it hits the printed surface, the extremely high kinetic energy is converted into heat energy, and the metal particles have been instantly melted by themselves, and its solidity is extremely high. And this method can create a variety of fusions and alloys, not only for printing metal, lazy science and technology's war-damaged version of the drone packaging box, the use of this metal, different materials when sprayed out, need to be finely adjusted, as well as countless calculations and simulations, this process of course also relies on Xiaobai's wisdom permission.

As he spoke, the mesh structure of the bracket 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 bracket, and after withdrawing, everyone found that there was a small L-shaped turning structure at the top of the bracket.

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

"This is the so-called printing first and then splicing?" Chi Jiafeng wanted to laugh a little and cry, Shaoxia, why are you so modest, this can also be called splicing?

"Technically and theoretically, it's really a patchwork. Wang Gandao, they are scientists, and scientists should seek truth from facts.

In fact, when they spoke, the No. 1 printer was not idle, it moved around, and printed all kinds of things in the marked position reserved on the ground, including fancy fences, cement benches, and all kinds of strange sculptures, and the No. 3 printer, the horizontal bracket printed in mid-air, also showed a slight arc shape, and other brackets stretched out on the truck, supporting the printed brackets, at a distance of about 30 meters, the cylindrical shape of the printing bin exited again, and at the end of the bracket, there was a T-shaped reserved interface。

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

A lot of people are staring at printer No. 3 because they're curious about what to do with the print bin when it reaches the bottom, how to get out of the completely enclosed glyph structure.

Then I saw the printing compartment crack with a click, splitting into two halves, revealing the dense printing nozzle inside, shaped like a crab's foot, Chi Jiafeng took the opportunity to click and snap a picture, Wang Qian shrugged with a smile, and did not stop it.

"Is this, planning to fence off the entire research institute?" Chi Jiafeng asked, looking at the various pavilions, sculptures and flower bed fences, and then looking at the more than ten meters high sky bridge, Chi Jiafeng suddenly felt that he knew what Lazy God Technology was planning to print.
