material engineering knowledge to produce substitutes for damaged organs and tissues. Early efforts to
repair bodily defects were already being made in the time of the ancient Egyptians, who believed in the life of the human body
and cared greatly about the integrity of the body.
Archaeological research has shown that even then
dentures, for example, were still being taiwan phone code produced. However, the term tissue engineering itself was not coined until 1988
at a meeting of the National Science Foundation. In the 1990s, there was a wave of
research to develop substitutes for almost all organs, and numerous
innovations, which marked a milestone for the medical 3D printing market.
To start the organ bioprinting process, doctors usually begin with a biopsy, i.e. the removal of part of an organ or tissue.
Extraction of a small piece of tissue. This allows the cells to be separated and grown outside
the human body. Cell development takes place inside a special sterile incubator or
bioreactor, which by its conditions resembles the internal temperature and oxygenation of the human body.
The cells are then allowed to mix with the biotouch, the non-cellular part of which can become a
laboratory. The biomaterials used in the printing process must be non-toxic, biodegradable and
biocompatible, to avoid a negative reaction from the organism.
