Scientists from all over the world are trying to use3D printing technology to create artificial organs. If they can prove their safety, effectiveness and durability, in the future, mankind will be able to forget about the donation, and introduce artificial analogues into the bodies of people who need healthy organs. Previously, researchers from Switzerland managed to create a mechanical copy of the human heart, but it was printed from silicone. Since silicone can be rejected by the body, scientists should have created a heart from the natural tissues of a person — this they finally managed to do.
So, at least, scientists fromTel Aviv University - to print a small heart, they used only human tissue that would not be rejected by the body. The structure of an artificial organ includes the vessels necessary for its work, collagen protein to create connective tissue and various biological molecules.
This is the first time that someone has successfully designed and printed a whole heart with cells, blood vessels, ventricles and cameras.

As a biological ink to print the heartA “personalized hydrogel” was used, on the basis of which lay down the fatty tissues extracted from the human body. Researchers claim that the heart is capable of shrinking, but it is important for them to ensure that its cells begin to work together. It’s too early to say that such a heart is able to completely replace a donor organ - researchers will have to work on all the minuses found.
