In the US, learn to "print" human blood on a 4D printer


Additive Technology over the past few years have stepped far forward. Today on a 3D printer print items that are components for various equipment and electronics, buildings and even organs for transplantation. In particular, last year, scientists from Israel managed to create living heart.


However, the development of the US University of Medical Sciences and the Geneva Fund, for which the Pentagon has already allocated funds, could be a real breakthrough. It is about creating a bioreactor that can "print" blood cells of any group. At the same time, to grow the necessary amount of blood for transfusion, you need only a small supply of biomaterial.

The essence of the device called 4D Bio3 will be the use of the so-called technology of four-dimensional bioprinting. The latter is based on the use of nozzles, which instead of powder (as in a 3D printer) will provide high-precision injection of growth accelerators into biomaterial. At the moment, successful experiments have been conducted with red blood cells.

The importance of developing American scientists is hard to overestimate. After all, its implementation will allow military doctors to receive blood for transfusion of any group directly in the field.

      Although 4D printers for printing various bio materials began to be studied / applied 3-4 years ago, but successes are impressive.
      I googled in English. and found a huge number of developments in many countries, two below.

      2017 "4D Bioprinting makes the smallest synthetic blood vessels to date"
      https://3dprintingindustry.com/news/4d-bioprinting-makes-smallest-sythetic-blood-vessels-date-123036/

      2020 "Four-dimensional bioprinting: modern developments and applications in bone tissue engineering"
      https://www.sciencedirect.com/science/article/pii/S1742706119307172

      The use of such printers will help astronauts at stations and during long flights. As Gorbachev said, “the process has begun” ..

        Hospitals in the United States began to fire employees who, in an interview with the media or on social networks, tell us how things really are with the American healthcare system.

        So, an emergency doctor in the state of Washington last Friday lost his job after posting on Facebook. It said that the measures taken by Washington are insufficient, and more tests should be carried out on COVID-19. A similar attitude on the part of employers was encountered by health workers in Chicago, New York and other cities.

        PS You, using advertising, hide the real situation of medicine in the USA.

      Stepping does not work, too difficult. So it remains to draw pictures.

        It’s not possible to wash, it’s too difficult

        mor7d, tell how Einstein steal the theory of relativity.
