Abstract
Bioprinting is a combination of 3D printing techniques and tissue engineering, using “bioinks” in order to give the tissue the desired spatial orientation. Combining pure engineering techniques with biotechnology offers some technical challenges of effectivity and biocompatibility, as the printed cells tend to be damaged by the printing process. Bioprinting has however the potential to bring organogenesis and other regenerative techniques an important step further. In the best case, it could be used to print whole organs with the original DNA of the recipient which would not only eliminate the necessity of immunosuppression with all its side effects but could also solve allocation problems and other ethical problems and controversies around organ transplantation, freeing the related ethical discussions from the pressure of urgency and emergency. Applying and combining very different techniques, an individual risk assessment for each experiment is inevitable, but in addition to specific risks a broader perspective on the social consequences and potential use and risks of established application ought not to be neglected.
