The goal of this experiment was a rabbit with a fractured right hind leg.

The rabbit's right hind leg was broken at some point and limped when he saw the X-ray film he took, and he immediately took a breath of air conditioning.

On the film, the rabbit's right hind leg was broken into more than a dozen pieces like his arm. It is no exaggeration to say that if, according to normal circumstances, such bones are very fragile even if they are connected, but if a layer of metal shell can be printed with a 3D printer...

"Charge, start printing and modeling rabbit's legs," Li Xingyuan ordered the smart housekeeper's chariot: "You can do such a small thing, right?"

"Yes, sir," the sound of the chariot sounded: "I am the latest generation of stewards, and I can complete most of the calculations and operations through the robotic arms in the laboratory. Modeling is one of the things I can handle. Please wait, sir, and it will be fine soon."

The chariot then began to model the rabbit's hind legs.

The complex modeling process began to be shown on the screen of the lab, including even the smiling bulge among the bones.

Li Xingyuan sighed: "It's really much more convenient to have this thing, otherwise it would take at least two or three days to rely on me to manually model it."

"Yes," Wang Hao smiled and said, "Computers are indeed much faster than humans in terms of computing. By the way, Brother Li, this time we will first test the skeleton shell or directly replace all its leg bones with metal?"

"Let's experiment with the metal shell of the bone for the time being," Li Xingyuan said: "The success rate will be higher. If you replace all the bones, the failure rate will be too high, let's do it bit by bit."

About twenty minutes later, the sound of the chariot sounded again: "The modeling was completed, and the bones of the left and right legs were completely symmetrical."

"Okay," Li Xingyuan pushed Wang Hao directly to a medical-specific surgical cabin in the laboratory and said, "This time it's quite expensive. It's much more convenient to do experiments with this surgical cabin. Now we're ready to start."

He said as he arranged the chariot directly: "Put the rabbit into the cabin and prepare to start the surgery."

"Okay," the chariot agreed, and soon, a slight sound of gear friction came from the surgical cabin. A glass door retreated to both sides, revealing the technology bed used for experimentation. The technology bed was not big, two meters long and one meter wide. Next to the bed were various mechanical arms, with scalpels, laser cutters and other things installed on it.

And just above the operating bed, there is a strange device. The device seems to be connected to a white metal cylinder with a probe. This guy is the core of everything, the 3D biological tissue printing system.

Next, Wang Hao saw several robotic arms extending from around the surgical cabin, and the rabbit was put into the cabin, the anesthesia was done, and then the body was fixed.

Whether the rabbit's experiment can be successful directly determines whether his arm can be restored, so Wang Hao is still very concerned.

Soon everything was ready. The scalpel controlled by the chariot gently cut the rabbit's hind legs, revealing the broken leg bones inside. According to Li Xingyuan's instructions, the chariot first put the rabbit's leg bones together and fixed them, and quickly fixed them. Then the very high-end 3D printer began to work.

"Squeak squeak"

The sound of gear rotation sounded, and Wang Hao saw the 3D printer start to work quickly, quickly printing a layer of metal on the broken bones.

Titanium alloy raw materials are relatively expensive, so this time Li Xingyuan only uses ordinary stainless steel metal.

The working efficiency of the 3D printer is amazing, but that can only be considered relative. The beginning of printing took more than an hour. Wang Hao simply saw a thin layer of metal gradually covering the newly connected bones from scratch.

"Success?" Wang Hao stared at the top of his eyes and looked carefully, and asked Li Xingyuan while looking, saying, "Is this successful?"

"I don't know at the moment," Li Xingyuan was nervous and his palms were covered with sweat. After all, he was only in the experiment stage before, so he was not sure whether it was really possible.

Soon, the entire printing of a layer of bone shell was finished, and the shell of the bone looked a little thicker than before, about a thickness of less than a millimeter.

But Wang Hao knew that just such a thin layer could already make the rabbit's leg bones stronger than geometrically.

After printing the skeleton shell, the chariot began to suture the rabbit's skin quickly. From the beginning of the operation to the completion of all sutures, it was about three hours in total.

Wang Hao and Li Xingyuan stared at the rabbit intently. After more than ten minutes, the rabbit finally moved.

"The anesthesia effect has passed," Li Xingyuan whispered: "I don't know what the effect is."

As the two of them watched, the rabbit first turned over and stood up, then raised his head and looked around, and soon, the rabbit took two steps on the operating table tentatively.

"It seems, it's not lame anymore?" Wang Hao looked at the rabbit in amazement: "It seems that nothing is wrong with its hind legs!"

"We are...successful?!" Li Xingyuan stood there first, then the smile on his face became bigger and bigger. Soon, he jumped up: "Hahaha! Successful! We succeeded!"

Wang Hao was also very excited.

After all, if the rabbit succeeds, there will probably be no problem with his own arms.

The two of them observed for a while, and then Li Xingyuan said, "What you need to see now is what will happen after the rabbit's hind legs recover." Speaking of this, his eyes turned, looked around, and then whispered: "Brother, although this experiment was successful, we can't be happy too early. This is obvious now. It's just that your hand is cured and we can't escape from here, so what we need to study next is the real focus!"

Wang Hao naturally understood what Li Xingyuan said.

If they were in China now, then the major success of this experiment could definitely be celebrated for ten days and half a month, but here...

But this level is obviously not enough!

Because, both of them had to consider how to escape from here!

"Brother, what do you mean," Wang Hao thought for a while, and then said, "I need to replace all the bones of my arms with titanium alloy?"
