The team of researchers from the Taiwan Institute of Technology (ITRI) has developed a new technology for 3D printing of artificial human skin.
This technology has been implemented in a 3D bio-printer that works just like any 3D printer. The only difference is that the biotin it uses is made up of living cells and biological elements such as proteins. This biotin, allows to print a three-dimensional structure equivalent to human skin in Petri dishes to cultivate living cells.
HOW IS THE PRINTING?
The impression reproduces by way of imitation the human epidermal structure, composed of the horny layer, the granular layer, the spiny layer and the basal layer. Said living tissue is called EPiTRI and it produces a stable reproduction that complies with the international standards on the validation of tests such as skin irritation and corrosion . This type of printing is done at a controlled temperature in a laboratory. The bioprinter does not need more than a second to be able to print enough skin and thus meet the requirements of the medical industry to be used in Petri dishes, where tests are done.
The ITRI researchers believe that "bionic" skin is used by animals when carrying out clinical trials in various sectors, such as medically, pharmacy products or medical supplies.
WHAT ADVANTAGES DOES IT HAVE?
Beyond what the crop may suppose, this type of printing related to the manufacture of human skin, reduces both costs and times . Regarding its future, it is estimated that the bioprinter has direct medical applications in patients that require a skin transplant (burns).
The printing process in this case, includes the use of patient cells to incorporate them into the 3D printer biotin, although it will be some time before the 3D human skin printing method with this type of medical applications is available for patients.
