Moreover, it’s all home-cooked dishes!

"Sometimes it's pretty good to eat Chinese food. My favorite is your Sichuan Province Mapo tofu!"

This is not the first time Stark has eaten Chinese food, and he is very skilled in using chopsticks.

The two of them talked about eating and talking about it, from some trivial matters to physics experiments and material design.

Tony was also secretly surprised, because Lu Cheng's research on materials seemed to be more thorough than him.

This also made Tony even more curious about Lu Cheng’s new products!

After lunch.

Waited for a while.

Four or five big men moved the 3D printer to the villa under the leadership of Tony's driver.

Tony looked at the ordinary printer in front of him and raised his eyebrows:

“Is this your new product?”

"Apart from being a little taller, it doesn't seem to be much different from an ordinary printer."

Lu Cheng said:

"You will know when you connect to the computer!"

Tony quickly found a computer and connected it to a 3D printer!

Lu Cheng said:

"Just find a modeling diagram online for me!"

Tony spoke:

"What kind of modeling drawing is needed?"

Lu Cheng said:

"You should have a modeling diagram for making steel suits here, just use this."

Tony nodded:

"Jarvis, import the modeling diagram of the steel suit into the computer."

soon.

Jarvis's voice sounded:

“It has been imported…”

Lu Cheng immediately found the modeling diagram of the steel set on the desktop and then connected it to the 3D printer.

"You should also make steel sets here, use the remaining materials, and find them for me."

"As long as the materials are enough, I can print out a steel set for you right now!"

Tony is doubtful:

"You wait, I'll go find..."

Not long.

Tony took all the materials for making the steel set and put them in front of Lu Cheng.

"These are the raw materials. The materials used in each part are different, and they require very preciseness and require the assistance of various professional instruments to complete. Are you sure this machine can print out a complete set of steel suits directly?"

Even though Tony has seen a lot of black technology, he is still skeptical about this 3D printer!

Lu Cheng clicked on the modeling diagram and put the materials needed for each part of the steel suit into the material port one by one!

then.

Operate on a 3D printer and design the operation process!

After finishing, the start button was electrocuted.

The next moment.

The 3D printer started running.

"That's it?" Tony was slightly stunned.

Lu Cheng shrugged:

"Well, according to the complexity of the steel suit, it will take about two hours to do it!"

Tony's eyes widened, looking disbelieving:

"Two hours?!"

It will take him half a month to one month at the earliest to make a steel suit!

This broken machine can make a steel suit in two hours?

Lu Cheng smiled:

"It's only two hours left. Just wait and know whether what I said is true or false."

Tony spread his hands and said:

"Okay, I'll go to the beach to catch a wave first and come back later."

After solving the problem of palladium poisoning, Tony regained his free and easy personality.

Lu Cheng sat on the sofa and watched the news with peace of mind.

Two hours later.

Tony returned to the villa in a dress of beach pants.

"How is it? Have you printed it?" Tony said.

"Beep, print is finished!"

As soon as he finished speaking, the 3D printer rang out a prompt.

Lu Cheng smiled, walked to the printer, opened the hatch, and took out a complete set of steel suits.

"Look, is there any difference from your steel suit?"

Tony approached and looked carefully at various parts and materials of the steel suit.

After a moment.

He was a little surprised:

"This steel suit is really printed out by this thing?!"

He had just confirmed that every structure of the steel suit was exactly the same as what he designed!

Even the proportions in some places are more accurate than the steel suit he designed himself.

The most important thing is that this steel suit only took only two hours from the end of production to the final completion!

He finally understood why Lu Cheng was so confident about his product!

Once this product is born, it may even directly subvert an industry!

Lu Cheng spread his hands:

"Of course, I don't have the ability to prepare the steel suit in advance!"

Tony looked at Lu Cheng with complicated eyes:

"Where did you get this high-end technology? It's so subversive!"

He didn't believe that an agent could make such an epoch-making product in just two months.

This not only requires high IQ and imagination, but also requires the accumulation of experience!

The launch of an epoch-making product must draw on the experience of predecessors.

However--

Although this 3D printer is called a printer, it has nothing to do with the printer.

This technique seems to appear out of thin air!

There is no past technology that can be used as a reference.

Lu Cheng shrugged:

"We SHIELD are not only going to investigate cases, but also have a lot of black technology that you don't know."

Lu Cheng turned the blame to SHIELD without hesitation.

He knew that with Tony's personality, he would definitely not investigate deliberately.

After a pause, Lu Cheng continued:

"How about this technique, you should be able to give a brief introduction at Stark Expo in five minutes."

Stark looked at the steel suit in his hand:
To be continued...
