On stage.

Lu Cheng was shrouded in spotlight and instantly became the focus of the entire expo!

There were cheers, exclamations, and waves of doubts in the crowd.

The sound waves seemed to turn into an ocean, and they wanted to submerge Lu Cheng.

Only when Lu Cheng stood in the center of the stage did he know what it means to pay attention to!

In terms of costume comparison, Iron Man is slightly better.

Tony naturally retreated aside and handed the stage to Lu Cheng.

The audience in the audience couldn't help but sigh when they saw Tony giving up the stage for an unknown character.

"Who is this person? He actually asked Iron Man to personally promote his products?"

"Isn't it because I gave the money?"

"Idiot, who else can buy Iron Man with money in this world?!"

"Why is it Chinese, made   in      china?"

"I'm even more curious, what product he invented, so that Iron Man could promote him on such occasions!"

Many entrepreneurs have a look of interest in their eyes.

They knew that Tony Stark was arrogant and could not do unscrupulous publicity on important occasions such as the expo for the sake of someone or money.

Doing so is equivalent to smashing Stark Industrial’s signature.

The only possibility is that the product is really good, so Tony lowered his posture and promoted it.

Lu Cheng looked at the boiling crowd in the audience, made a suit, and slightly adjusted his emotions.

It was not the first time he gave a speech in public, so he was not too nervous.

He picked up the microphone and spoke:

"Maybe many people are wondering, oh, who is this person, how could Tony promote him in such a public place."

"Tony, you're going to be kidnapped and blink!"

After saying this.

There was a burst of laughter from the audience.

The atmosphere suddenly became even more warm!

I have to say that the Americans are very joking in this kind of half-joking speech.

Lu Cheng continued:

"come    on, he is the famous Iron Man. It is much harder to kidnap him than to kidnap the president!"

Another burst of laughter.

A short two-line speech directly brought the atmosphere to the gao trend.

Seeing that the audience's emotions were mobilized, Lu Cheng entered the topic:

"Okay, Tony hasn't given me much time to promote it, so let's get back to the point. My name is Lu Cheng, and my company is Chengxi Technology... The product I'm going to introduce next is called a 3D printer!"

"Everyone present should not be too unfamiliar with the printer, but my printer is a bit special."

“It not only prints paper, but more importantly, it can also print out real items!”

"From small polishing jewelry, to large building cars and even aircraft carriers, you can print it out with just these 3D printers."

"There is no need for huge labor, just make relevant modeling drawings and prepare the materials, and you can print out the original product in its original form!"

The ordinary people below were a little unaware of it.

However, some bosses heard something extraordinary.

"This guy said he could print the entity?"

"Well, I should be giving him a picture to completely restore the things in the picture."

"How is that possible? If this is true, then wouldn't this be magic?"

"Don't rush to draw conclusions. Since Tony personally recommends it, he must have verified it in advance, let's take a look!"

Although most of them do not believe what Lu Cheng said.

However, given the face of Iron Man, they still patiently waited for Lu Cheng's subsequent text.

Lu Cheng glanced at the audience and smiled:

"I know, there must be many people who will question me. After all, such a product has indeed subverted people's past perception."

"So, no matter how much you say, it's better to demonstrate it yourself."

"Please send my 3D printer up and cast the demonstration screen onto the big screen!"

Just finished speaking.

The stage rotated and sent the 3D printer that had been ready to connect to the computer to Lu Cheng.

Everyone looked at the 3D printer several meters tall in front of them, and their eyes showed a curious look.

They also wanted to see what magical things are there in this device that looks similar to a printer but is quite weird.

Lu Cheng walked to the computer and spoke:

"Next, I will demonstrate to you the specific usage of 3D printers!"

"Please watch carefully, don't blink."

"The next time is the moment to witness the miracle!"

"First of all, this is a 3D modeling diagram of the Desert Eagle that I made in advance. I will use this 3D printer to make this Desert Eagle within 3 minutes!"

After saying this.

Lu Cheng walked to the 3D printer and spoke:

"After importing the 3D modeling diagram into the printer, the next thing to do is very simple. You only need to put the materials used to make the Desert Eagle into the material port one by one, and then use a 3D printer to adjust the position and proportion of the material!"

"Finally, just press the Start button and the job is done."

"The next thing we have to do is wait patiently for a few minutes."

The people below looked at Lu Cheng's operation and couldn't help but look surprised.

"That's all?"

"No, it will take at least one week for a desert eagle to be polished to completion, right?"

"It's not just a model, it can only be seen but not used, right?"

"If that's the case, it's too boring."

Just as everyone was talking, three minutes passed quickly.

During these three minutes, Lu Cheng was not idle. He took out the promotional video of the 3D printer and played it to deepen the impression of the people.

"Beep, the printing was successful!"

Accompanied by a reminder sound.

A delicate desert eagle was sent out from the hatch of the 3D printer.

Lu Cheng held the Desert Eagle and gave the camera a close-up.

Whether it is size, structure, or even the patterns on it, they are exactly the same as the 3D modeling diagram!

Seeing this, some business owners showed shock.

Let’s not talk about whether this desert eagle is a model.

With this exquisite workmanship, the modeling drawings are perfectly restored, which is enough to be called a cross-age product.

These entrepreneurs naturally think longer than ordinary people.

If this 3D printer can really perfectly print the design of 3D modeling diagrams, it will play a huge role in other fields!

Even, it can save a lot of machine and labor costs.

Lu Cheng looked at the audience below and spoke:

"Maybe, many people will question that this Desert Eagle is just the same model, but what I want to say is that this is not a model, but a real gun!"

While talking.

Lu Cheng slowly took out a bullet and loaded it!

He raised his arm and shot into the sky!

Bang!

The roar of bullets echoed in an instant in the venue, overwhelming all the noisy talk!

For a moment.
