This bachelor thesis deals with the technology of 3D-Bioprinting as a solution to the lack of organ donation. Everybody in Austria is an organ donor, except the person had entered an objection during his lifetime. Still there is, like in many other countries in Europe, a lack of donated organs. In the future the lack of organs will increase, in case of the demographic change and the cumulative ageing of the population. Scientists are on the search, for a solution, to solve this problem. It looks like they have found a solution, with the technology of 3D-Bioprinting. It should work with a Bio-Printer, which is able to print a bio ink in a substrate or scaffold. The scaffold has the task to hold the bio ink in the right shape. So, the organ grows layer by layer. Bio ink consists of a connection between cells, biomaterial and hydrogel. When the organ is printed it must age for a specific period. So far it is not possible to print functioning and transplantable organs. The research in this sector is relatively new but it can exhibit results in the recent past. In course of the consistent development, social contents are arising, which must be respected. Considering ethics, there are not many suggestions, when it comes to the use of the technology of 3D-Bioprinting, as an alternative for the organ donor. To push on the research and to develop bio ink it is sometimes necessary to use embryony steam cells, this beg up ethical questions. The legislative authority had to grapple with Bioprinting, to find rules for the dealing, handling and the liability of artificially made organs. On the international market, 3D-Bioprinting is predicted to have a successful future.
