Chapter 665: The Omnipotent Laser (2)
With the last part completed, the skeleton of the entire powered exoskeleton, the transmission, is fully formed, like a broken bone, floating in the gel.
"No wonder it's called a powered exoskeleton!" This is the common thought of everyone who saw this scene.
The metal parts suspended in the gel look very similar to human bones.
All the guests here, including Qingzhong Yang, have only heard of the 3D printing technology of Lanshen Technology, but it is the first time to see it with their own eyes.
And people on the Internet have only seen Heqing's process of creating and printing 3D buildings before, not such a detailed printing process.
The printing material sprayed from the nozzle is sprayed on the gel. At first, it is a thin layer, like gray powder covering the gel, and then more metal particles, through the "kinetic energy metallization" effect, at Mach 6 The above speed is sprayed onto the previously covered metal particles, and quickly combines with the previous metal particles.
The gel absorbs the excess momentum and heat, and the momentum brought by the sprayed particles also makes the printed part sink continuously. The printing process is repeated, and the metal is layered on top of each other. This process makes people think of In the famous sci-fi movie "The Fifth Element", through the genetic information contained in a hand, the lens of the human body is manufactured by 3D printing.
This process even looks more sci-fi than the special effects made in the movie.
Where the metal and gel meet, the heat bonds the metal and the gel, as if coating the metal with a fancy black protective coating.
"Papa, papa!" After all the skeletons were printed, Ding Guocheng couldn't help applauding. It took less than five minutes for a powered exoskeleton to print from the beginning to the end.
Whether it was them or the netizens who were watching the live broadcast, they all stared at it for five minutes.
The whole process is very beautiful and fantastic, but now there is a problem, that is, all the parts are discrete.
The powered exoskeleton quietly submerged in the gel is like a human skeleton that has been disassembled and placed on the dissecting table, and now it has to be assembled.
How to assemble it? manipulator? Or take it out of the gel and assemble it manually?
It should be a robot arm. After all, Nan Ming wants to show off his skills, and manual assembly is a bit outdated.
Almost everyone thinks so.
At this moment, a mesh-like metal plate at the bottom of the gel lifted the powered exoskeleton, and all the gel flowed out from the holes in the mesh, and now the powered exoskeleton parts placed on the plate are similar to The supporting structure of the phalanges, metacarpal bones, and wrist bones are all available. Apart from being black, it looks more like a human skeleton placed on an anatomy table.
How to assemble it?
Almost everyone is thinking about this question.
At this moment, the powered exoskeleton in the container suddenly moved. It seemed to be driven by an invisible force, starting from the smallest phalanx. Of course, the phalanx of the powered exoskeleton is not the structure of the human body, because it is only used to Loaded, it looks like two thick hooks.
Driven by an invisible force, the two hooks suddenly moved at the same time and combined with the metacarpal bones. With a "click", the buckles between the two parts were combined.
This sudden movement startled everyone who was staring inside the container.
Once this process started, it never stopped. After the two phalanges were combined, the triangular metacarpal began to move, as if at this moment, these newly printed metal objects suddenly came to life.
"Ka Ka Ka Ka..." The continuous and dense sound, the structure that resembles human bones, and the strange self-assembly movement made the people watching suddenly feel chills down their backs, and cold sweat flowed out.
This...couldn't be haunted!
On the opposite side of the earth, at the press conference site, it was already past nine o'clock in the evening, and it was pitch black outside the window of the press conference. The person in charge of Raytheon Company's hairs stood on end when he saw this scene, and he shivered.
More people saw this scene through the Internet, and I don't know how many people screamed in fright.
What exactly is going on?
"I see, is this the magnetic field used?" Ding Guocheng was startled just now, but he quickly calmed down and guessed.
"No, this is the laser peening plus laser propulsion technology used." Nan Ming said.
Just for the sake of safety, the glass facing everyone can filter out light with a fixed wavelength, and the scattered laser light is filtered out by this glass, so it looks very weird.
"Laser peening!" Qingzhong Yang was stunned: "I know this technology! The tip of the propeller blade of the aircraft must be treated in this way! What level has your laser peening technology reached?"
"Uh, a few thousand GPa." Nan Ming rubbed his nose, "We're still at the beginning of this technology."
Qingzhong Yang suddenly didn't want to talk anymore. The laser peening he knew of a domestic research institute had just reached tens of Gpa, and the commonly used ones in industry were only 7 or 8 Gpa.
In fact, this technology was one of the technologies that Zhang Qing showed Nan Ming back then.
Shot peening is a kind of cold processing method, which is to spray high-speed projectile stream onto the surface of the object to make the surface of the object plastically deform and form a strengthening layer with a certain thickness. Strictly speaking, the 3D metal printing technology "kinetic energy metallization" used by Lanshen Technology is a processing method combined with "shot peening", so the processed parts have strong stress and high strength, which can be Resists strong metal fatigue.
Of course, this is traditional mechanical shot peening. Compared with mechanical shot peening, laser shot peening has higher efficiency and stronger effect.
Its principle is roughly equivalent to using high-intensity laser pulses to irradiate the black coating on the surface of the workpiece, so that the coating on the surface of the workpiece is instantly ionized to generate a powerful shock wave.
Now the outer layer of the powered exoskeleton is covered with a layer of completely transparent gel. Under the constraints of the gel, the shock wave will propagate inward, and the shock wave will penetrate the entire workpiece, further strengthening the workpiece.
This kind of 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 human beings.
Since there is a shock wave, it will naturally generate force on the workpiece. Just slightly adjust the laser in different directions to adjust the force direction of the workpiece.
Numerous lasers simultaneously "laser peened" the workpiece, and by the way, they also used the principle of laser propulsion to push and assemble it. This is the real reason for the weird scene just now.
In sci-fi movies, laser guns are often seen shooting at each other. A hole appears in the body of the person shot by the laser gun, and he falls silently to the ground and dies.
But in fact, after being hit by a high-intensity laser pulse, the laser that is as thick as the human body and exists for a shorter duration does not necessarily penetrate directly, but is more likely to knock people into the air. Bullets hit pretty much the same. (To be continued.)
