Volume 2: Qingyang University Chapter 665: The Omnipotent Laser (2)

Next chapter

With the completion of the last part, the skeleton and transmission of the entire power exoskeleton have been fully formed, like a fragmented skeleton, floating in the gel.

"No wonder it's called a powered exoskeleton!" is the common thought of everyone who saw this scene.

The metal parts suspended in the gel look very similar to human bones.

Among the guests present, including Qingzhong Yang, they have only heard of the 3D printing technology of Lazy God Technology, but it is the first time to see it with their own eyes.

And the people on the Internet have only seen the process of creating and printing 3D buildings in Heqing before, not such a delicate printing process.

The printing material ejected from the printhead is sprayed on the gel, initially as a thin layer, like gray powder covering the gel, and then more metal particles, through the guò "kinetic metallization" effect, are sprayed onto the metal particles that were previously covered by Mach 6 or more, and quickly combine with the previous metal particles.

The gel absorbs excess momentum and heat, and the momentum brought by the ejected particles also makes the printed part continue to sink, and the printing process is constantly repeated, and the metal is superimposed layer by layer, which makes people can't help but think of the famous science fiction movie "The Fifth Element", in which the genetic information contained in one hand is used to create a human body lens with 3D printing.

This process, even more science fiction than the special effects made in the movie.

Where the metal and gel come into contact, the high temperature binds the metal and gel together, like a strange black protective layer on the metal.

"Bang Bang Bang!" After all the bones were printed, Ding Guocheng couldn't help but applaud, and it took less than five minutes for a power exoskeleton to be printed from the beginning to the completion of printing.

And whether it was them, or the netizens who were watching the live broadcast, they all stared at two eyes. I watched it for five minutes in a daze.

The whole process is very aesthetic and incredible, but now there is a problem, and that is that all the parts are discrete.

A powered exoskeleton that sits quietly in a gel. It's like a human skeleton that is disassembled and placed on a dissecting table. Now it's going to be put together.

How do you assemble the manipulator or take it out of the gel and assemble it by hand?

It should be a manipulator, after all, Nanming wants to show off his skills, and manual assembly is too outdated.

That's what almost everyone thinks.

At this moment, a mesh-like metal plate at the bottom of the gel holds up the powered exoskeleton, and all the gel flows out of the mesh holes, and the powered exoskeleton parts that are now placed on the plate are from the hand to a phalanx-like support structure. To the metacarpal bones and carpal bones, everything is available, except that it is black, it is more like a human skeleton that is placed on the dissecting table.

How do you assemble it?

Almost everyone is thinking about it.

At this moment, the kinetic exoskeleton in the container, all of a sudden, moved, as if driven by an invisible force, starting from the smallest phalanges, of course, the phalanges of the kinetic exoskeleton are not the structure of the human body. Because it's only used to carry weights, it looks like two thick hooks.

Driven by an invisible force, the two hooks suddenly moved at the same time. Combined with the metacarpal bone, there is a "click", and the buckle between the two parts is combined.

This sudden movement startled everyone who stared inside the container.

As soon as the process began, it never stopped, and after the two phalanges were combined, the triangular metacarpal bones began to move, as if at this moment, these freshly printed metal objects suddenly came to life.

"Click, click, click......" continuous and dense sound. It resembles a human skeleton, with strange self-assembling movements. The person watching suddenly had a chill down his spine and cold sweat coming out.

This...... It can't be haunted!

The opposite side of the globe. At the press conference, it was already more than nine o'clock in the evening, and it was dark outside the window of the press conference.

More people, through the guò network, saw this scene, I don't know how many people were so frightened that they screamed.

What the hell is going on?

"I see, is this the magnetic field used?" Ding Guocheng was also startled just now, but he quickly calmed down and guessed.

"No, this is the laser shot peening plus laser propulsion technology utilized. "Nan Ming Dao.

"Laser shot peening!" Qingzhong Yang was stunned: "I know this technology! The tip of the propeller blade of the aircraft must be processed in this way! What level has your laser shot peening technology reached?"

"Uh, a few thousand GPAs. Nan Ming touched his nose, "This technology is still in its infancy. ”

Qingzhong Yang suddenly didn't want to speak, the laser shot peening of a domestic research institute that he knew had just reached dozens of GPAs, and the commonly used ones in the industry were only 7 or 8 GPAs.

In fact, this technology is one of the techniques that Zhang Qing showed to Nanming at the beginning.

Shot peening is a kind of cold working treatment, which is to spray a high-speed projectile stream onto the surface of the object, so that the surface of the object is plastically deformed, and a certain thickness of the reinforcing layer is formed. Strictly speaking, the 3D metal printing technology "kinetic energy metallization" used by Lazy God Technology is a processing method combined with "shot peening", so the processed parts have strong stress, very high strength, and can resist strong metal fatigue.

Of course, this is a traditional mechanical shot peening, and laser shot peening is more efficient and more effective than mechanical shot peening.

Its principle is roughly equivalent to using a high-intensity laser pulse to irradiate the black coating on the surface of the workpiece, so that the coating on the surface of the workpiece is instantly ionized and generates a powerful shock wave.

Now the outer layer of the dynamic exoskeleton is also covered with a layer of completely transparent gel, under the constraints of the gel, this shock wave will propagate inward, and the shock wave will penetrate the entire workpiece, so that the strength of the workpiece will be further strengthened.

This process is like using a hammer to forge a workpiece, but the hammer used here is a laser, and the forging power is countless times that of humans.

Since there is a shock wave, it will naturally exert force on the workpiece, and the direction of the force on the workpiece can be adjusted by slightly adjusting the laser in different directions.

Countless lasers simultaneously carry out "laser shot peening" processing on the workpiece, and by the way, the principle of laser propulsion is also used to push it into assembly, which is the real reason for the strange scene just now.

In science fiction movies, you can often see laser guns shooting, and a hole instantly appears in the body of the person who is shot by the laser gun, and he falls to the ground and dies silently.

But in fact, after being hit by a high-intensity laser pulse, the laser with a slightly shorter duration of this thickness of the human body is not necessarily a direct penetration, but more likely to send a person flying, and its impact force is very similar to that of an ordinary bullet.
