Hand rubbing nuclear fusion live in the wilderness

Chapter 471 3D Printing Human Organs
Compared with the more traditional assembly line production and CNC machining before, large-scale 3D printing factories focus on intelligent manufacturing.

As long as there are corresponding materials, it can very quickly turn the drawings in your mind into real parts.

The most important thing is that it can not only produce various ordinary spare parts in large quantities, but also realize those strange ideas in a small amount.

Complex or creative products can be designed more intuitively and efficiently.

For Won, this is more suitable than other processing equipment, and more suitable for his current situation.

Because he was just a person from the beginning to the end, except for the X-1 industrial robot, which needs mass production to make up for the labor shortage, other things only need a small amount of production.

For example, photosensitive analyzers and elemental analyzers in physical chemistry laboratories.

If these things are placed in the real world, a country's standing stock may be thousands of pieces or tens of thousands of pieces.

But for him, only one or two or three or four is enough.

Not only is the quantity small, but another trouble is that the manufacture of many equipment in his mind often needs to customize a special equipment for processing.

It is actually very troublesome to manufacture a special processing equipment for industrial equipment with such a small demand.

But 3D printing technology is different. You only need to prepare the corresponding materials and drawings, and it can process complex equipment for you at one time.

After all, no matter what shape it is, it can be resolved into a plane bit by bit.

It's a bit like the relationship between two-dimensional and three-dimensional. Countless two-dimensional planes are superimposed to form a three-dimensional solid.

Of course, this is just a metaphor. In fact, no matter how many two-dimensional planes are superimposed, it is impossible to become a three-dimensional space, because two-dimensional has no definition of 'height' or 'up and down', but three-dimensional has.

The audience in the live broadcast room were very interested in the 3D printing technology described by Han Yuan, and asked him to print something to see, otherwise they would not believe it.

In this regard, Han Yuan could only helplessly spread his hands, saying: "The 1D printing equipment used to produce the parts of the X-3 industrial robot has not been fully completed, and the materials are still in production. use."

"However, the 3D printers I saw on the way here have just been completed, and there are some materials that can be used, and I can show them to you."

"I don't know what you want to print out."

With that said, Han Yuan walked towards the printing factory that he had passed before, and heated discussions began in the live broadcast room.

[Anchor anchor, print out all domestic aircraft carrier models! 】

[Good guy, do you want to exhaust the anchor to death?You must know that the Inner Mongolia has been launched, a total of thirty units! 】

[How about printing a 3d printer with a 3d printer? 】

[Hahahaha, logic genius. 】

[There is nothing wrong with this statement. I really know that there is a company whose 3D printer uses a 3D printer to print out. 】

[Then the question is, which 3d printer printed the first 3d printer? 】

[Where are you next to this doll? 】

[Dolls are prohibited! 】

【exist?Don't consider printing a female chubby? ? ? 】

[Anchor anchor, is there any bioprinting material, you should print a girl for yourself!How long have you been single? 】

[Like upstairs! 】

【Upstairs! 】

[Hahahaha, pork heart with shrimps, but then again, it’s been six or seven years since I graduated from college, and now my children can make soy sauce, and the anchor is still single. 】

[Anchor: I'm single and I'm proud! 】

【Definitely!You are really despondent, sick, beautiful, and crazy. 】

Seeing these bullet screens, the corner of Won Won's mouth twitched. It has been a few years for these sand sculpture netizens, and they still look like this.

But then, he remembered something again, and said: "Although it is not realistic to print a living person, if 3D printing technology develops to the extreme, it is completely possible to print some human organs."

"For example, using cardiomyocytes, red blood cells, fat, body fluids and other materials to print a living heart."

"Or use scanning technology to scan the human musculoskeletal structure, and print out a bone to replace the original broken or broken bone is completely achievable."

As soon as these words came out, the live broadcast room erupted.

[Fuck, can this be done? 】

[This is awesome, it's really awesome. 】

[3D printing of human organs, good guy, if it can be realized, there will be no more diseases in the world in the future, and what is broken can be replaced! 】

[Brain: What are you talking about?Brain cancer: Are you kidding me? 】

[A few years ago, Tel Aviv University in Israel successfully used the patient's own tissue as the raw material to 3D print the world's first "complete" heart with cells, blood vessels, ventricles and atria. 】

[I just want to ask, can this printed heart work? 】

[Obviously it can't be used, if it really works, it would have been explosive news long ago. 】

[No, it is still available. Harvard University has printed bladders that can be used for human transplantation. 】

【real or fake? 】

[The anchor said this should be used for human transplantation, right? 】

【If possible, I'll print out a [-]cm cowboy first, now the [-]cm is too short! 】

[Tsk tsk, thirty centimeters, a donkey is not as long as yours! 】

[Seriously, if 3D printing technology really reaches this point, it will really be a technology that benefits all mankind! 】

In the live broadcast room, everyone is discussing.

3D printing a human heart, printing human bones, muscles and other things, if it can be realized, I am afraid that human beings will have no other diseases except for diseases in the brain, and we can replace them wherever they are broken.

Not to mention ordinary viewers, even people from various countries squatting in the live broadcast room were shocked when they heard the news.

3D technology printing human body components, if it can be realized, will definitely do more good than harm to society as a whole.

However, correspondingly, it will also bring many problems.

In this world, nothing is equal, only time.

In front of time, everyone has an end, no matter how poor or rich.

But for those who hold power and money, it is obvious that they hope that they can live longer, or even live forever.

Aren’t the technologies such as head transplant surgery, freezing technology, uploading the brain, infusing young people’s blood into oneself, replacing cerebrospinal fluid, etc. that are circulating in the world today all created by the super rich?

The purpose is only to make myself live longer.

If 3D printing can really print human organs, even the body, can it achieve immortality?
Even if immortality is impossible, life extension is certain, right?
Especially for those who knew about the brain wave signal reader, a bold idea flashed through their minds.

If, if 3D printing technology can really print a body, combined with brain wave reading technology, if the memory of the old body is read out and completely transferred into the new body before death, can it achieve eternal life?
After all, in terms of physiology, human beings are a bunch of compounds with a relatively complex structure, and the memory in the mind controls the overall behavior.

The essence of human memory is the billions of nerve cells in the brain, which interact with each other through synapses to form extremely complex interconnections.

Memory is the interaction between brain nerve cells, and its fundamental principle lies in the stimulation of brain cells from the outside world.

When a brain nerve cell is stimulated to excite, its synapses will proliferate or the sensing threshold will decrease.

This is human long-term memory and short-term memory.

Among them, synaptic hyperplasia represents long-term memory, and the decrease of induction threshold represents the memory that is picked up.

Whether it is short-term memory or long-term memory, its source is the stimulation of brain nerve cells.

Taking advantage of this point, it is entirely possible to write the copied memory into the new body manufactured by 3D printing technology through appropriate stimulation.

And a person with a new body that has all the memories and can move normally, is the life expectancy extended?
After all, the new body has all the memories of the former owner.

This is like the "grabbing the house" in Xiuxian's novels, it is the process of transferring one's soul (memory) from a garbage body to a better body.

This idea is too scary, but if it can be done, or if it is hoped to be done, I am afraid it will stimulate the flow of capital all over the world to this field.

Except for a very small number of people, the vast majority of people in the world wish they could live longer.

Especially for those super rich, if there is an opportunity to abandon that decayed and old body and replace it with a young body, everyone is willing.

In particular, this body is still printed by 3D printing technology, created out of thin air, and there will be no ethical issues.

In the simulated space, Han Yuan didn't know how much stimulation his words brought to the outside world.

If he knew, he would probably only say that you are overthinking.

Printing a living human body is impossible even with his current printing technology.

Don't forget that the 3D printing technology and equipment in his hands are all from intermediate equipment information.

In this regard, the current printing accuracy cannot perfectly print the thickness of capillaries, which means that the blood vessels in the printed organs will be very thick, visible to the naked eye, so it naturally does not have the blood circulation that self-generated capillaries have Function.

In addition, how to make the printed organs physiologically active and how to establish the organ's own metabolic mechanism in the body are difficult problems to solve in the short term.

However, from some perspectives, this is indeed a feasible and quite potential path.

At least it is much more reliable than stem cell tissue engineering.

But for now, printing some simple muscle tissues, such as simple structures such as ears and bladders, is still a long way from the liver and kidneys.

To truly print organs such as livers, kidneys, and lungs with complex structures, it is necessary to restrict them at the microscopic level and improve the precision control of the process to another level.

If you really want to do what the outside world thinks, I am afraid that only advanced knowledge information has such a technology.

If there is such a day, Han Yuan feels that he will probably not prevent it from coming.

After all, the transformation of human beings is an irreversible historical process. The natural body of human beings is too fragile, and it is normal to be weak and sick.

As long as you are alive, you can extend your life, and you can continue to enjoy life with a healthy body, it is good enough.

As for whether the replacement of the heart organ, or even the replacement of the body, is still a person, that is a question for philosophers and anthropologists.

At least this technology can largely solve the problem of human disease and the problem of organ trafficking, can't it?
For these, Han Yuan didn't think too much, and came all the way to the head of the 3D printing factory.

There are 3D printing equipment that are still under construction, but a small part has been installed and debugged, and there are also some printing materials such as resin, plastic, and metal powder.

Finding a 3D printing device that has been regulated, Han Yuan thought for a while and said, "Let me print some models for you."

As he said that, he bent his arms and said to the pager in his hand, "Xiaoqi, help me draw some 3D printing drawings according to the design of the cartoon characters stored in Taishan base."

"As for the material to print, choose from materials that can be used with this device and materials that have already been manufactured."

"Got it, Master!"

In the communicator, Xiao Qi's voice came out.

Compared with the unfinished artificial intelligence 'Xiao Ling' in the Amazon Rainforest Base, Xiao Qi's ability is still much stronger.

Especially after he allowed Xiaoqi to use the various program modules he wrote, there are more things he can do.

For example, the construction of large-scale 3D printing factories and nuclear fusion parks is presided over by Xiao Qi, and "Xiao Ling" is still just a preschool student who is learning from his predecessors, but this student is making rapid progress. Won estimates that when the core intelligence After the module is written, it can enter the social work.

After waiting for a while, Xiao Qi's voice sounded again in the communicator.

"Master, do you need Xiaoqi's help to transfer these printed drawings to the 3D printer in front of you?"

"Well, pass it on, and then control it to play the characters."

"Okay, master."

After Xiaoqi's voice fell, Han Yuan saw that the 3D printing equipment that had been banned in front of him started up.

At the same time, the audience in the live broadcast room also cast their gazes over.

The 3D printing equipment starts, and Xiaoqi enters the printing data of the cartoon characters and the information of the materials to be used, and the smart chip immediately starts to distribute the work.

After waiting for about half a minute, the mechanical arm in the 3D printing equipment moved quickly, and the material delivery pipeline fixed on the mechanical arm continuously delivered materials of various colors, and the silver-white substrate that fell on the bottom seat.

In less than 5 minutes, the first anime character model was completely printed out.

The speed was so fast that the audience in the live broadcast room were amazed.
