"First of all, I would like to thank everyone for accepting the invitation and going to Africa.

Secondly, I invite you, but also hope to have a deeper understanding with the world's top technology companies, in order to show our sincerity, today also specially invited you to visit our manufacturing capabilities."

After meeting every guest, Fan Yize said to the people:

"What you're seeing is our large 3D printer, and I'm sure you'll want to see how we make our products, and I won't say much.

As Fan Yize's voice fell, the engineer responsible for controlling the device on the CNC control equipment under the 3D printer also started the production process.

Under the watchful eye of the crowd, the 3D printer pointed to the huge raw material pool below and put dozens of laser beams of different colors.

The dense laser beam shines in the following raw material pool, like the slow flow of mercury in the raw material pool, there is a rapid change visible to the naked eye.

In the shocked eyes, only a huge circular object with a diameter of nearly ten meters was slowly emerging from the raw material pool and slowly rising.

In a circle of VIPs, Musk was the first to exclaim, saying in a trembling tone: "It's incredible, this is a launch vehicle."

Others who had not yet seen what this was, and after hearing Musk’s exclaim, they all showed a look of shock.

At the same time, he set his eyes on Fan Yize's body, and seemed to ask whether it was right.

Fan Yize's mouth slightly raised, said: "Musk is really the founder of the future space exploration technology company, the launch vehicle is indeed very familiar, yes, you see this in the raw material pool, gradually formed is a launch vehicle, after printing, its height will reach 95 meters, so far close to ten meters, is a heavy launch vehicle."

With a clear reply, Musk still looked at him and asked hurriedly, “But why can you print out the circuit board, electronic devices, control chips, engines, and vents inside, all directly into a whole?”

Fan Yize looked at Musk with some surprise and praised: "Mr. Musk, it is very good, and I quickly saw the core function of our 3D printer."

Fan Yize's words fell, Huang Wengang explained on the edge: "Gentlemen, our 3D printer is not a conventional printer, the full name is called 3D laser plastic molding machine, it can be printed according to raw materials, any existing material in the world, from small to rope fibers, large to alloy ceramics, and even the liver living organs of the human body, can be printed and molded."

It can emit five billion different color laser beams, the bottom of the raw material pool, the inside of the mixture of a lot of raw materials, and the specific color of the laser beam to play a role, when the laser beam to the following raw material pool, will produce a solidification reaction.

Therefore, according to the laser beam, as well as the printed content, put in the matching raw materials, you can quickly print out the corresponding products.

This well-printed product does not require assembly, does not require any rivets, and has the function of modular disassembly maintenance, from the structural strength of the product to the stability, which exceeds the mainstream manufacturing technology of today.”

Hearing Huang Wengkang's words, the obvious color of suspicion on the faces of the people was not that they did not want to believe the facts they saw with their own eyes, but that Huang Wengang said that this technology, for them, still belonged to a strange technology, which can also be called black technology.

"That is to say, in this raw material pool, there are different substances mixed together to print the alloy and the line of this very different thing, so how are these materials made?"Bezos raised the question.

It is also the world's top billionaire today, Bezos's problem, directly pointed to the core of this technology.

3D laser plastic molding technology, speaking, is not a distant technology, many research and development of 3D printing technology companies, can also make this technology, and in the early years there are similar products that can be put into use.

The real problem of 3D printing technology is the material technology, if the earth's material can be 3D printing to become the finished product, this is the most critical.

It is clear that the future technology group will inevitably master the unimaginable material technology, otherwise it will not be able to complete such a production process.

“Mr. Bezos, you have said the key to the problem, which also involves one of the core secrets of our group, so please forgive me for not being able to explain it.”He said very calmly.

Don't say that Fan Yize can't tell them, even if they can be told, can't tell them that I have the black technology of the base, there is an ore refinery, which can break down all the substances and then reorganize and become a product.

Therefore, this problem cannot be explained or explained.

And everyone present naturally knows that the life of an enterprise is confidential technology.

Of course, they also know that since they invite themselves to others to watch, they will inevitably have to be below.

Understand, will no longer speak out, people are just watching, in front of this huge launch vehicle, a little bit into the product.

The huge launch vehicle, a little displayed in front of the crowd, in the 100-meter-long raw material pool, the huge diameter of the launch vehicle extended a little bit.

When the entire 95-meter-long launch vehicle body appeared in front of everyone, the huge body made everyone deeply feel their own smallness.

The most shocking thing is that everyone saw a huge launch vehicle from a little bit and appeared in front of them.

After seeing the printing time of the entire launch vehicle, Musk said with emotion: "Such a huge launch vehicle, the entire manufacturing process actually takes less than half an hour, it is amazing."

Hearing Musk’s words, everyone was shocked that only half an hour had passed.

The manufacturing time of a launch vehicle is only slightly smaller than the largest launch vehicle, Saturn V, and only takes half an hour.

This kind of thing, no one will believe it, and if they do not see it with their own eyes, it is difficult to imagine that the human manufacturing industry has actually developed to such a height.

Huang Wengkang said: "This rocket will then be transported to the launch site, connected to the space module equipped with satellites, injected into the launch fuel, can be launched at any time, and after the space module into orbit, the rocket body can also be recycled and reused."
