Scientists from around the world are trying to use 3D printing technology to create artificial organs. If they can prove its safety, efficiency and durability, in the future mankind will be able to forget about the donation, and to introduce in the body in need of healthy organs of people their artificial counterparts. Previously, researchers from Switzerland have managed to create a mechanical replica of the human heart, but it was printed out of silicone. Since silicone can be rejected by the body, scientists ought to create a heart out of natural human tissues, they finally succeeded.
So, at least, say scientists from tel Aviv University — to print a small heart, they used only human tissue that will not be rejected by the body. The composition of the artificial organ includes the necessary blood vessels, the protein collagen to create connective tissue and a variety biological molecules.
This is the first case where someone has successfully designed and printed a whole heart cells, blood vessels, ventricles and cells .

As the biological ink print of the heart was used “personalized hydrogel”, which lay down fat tissue extracted from the human body. The researchers claim that the heart is able to contract, but it is important to make her cells began to work together. To say that such a heart is able to completely replace the donor organ, and researchers have to work on all found disadvantages.
How you consider, whether printed on a 3D printer organs to save mankind from the necessity of transplantation of donor hearts, kidneys and other body parts? Share your opinion in comments or in
