Ethical Impacts
Within this field of science, embryonic stem cells must/should be taken from human embryos in the early stages of development so that the organs/tissues printed can be cultivated from them. However, this is one of the major controversies under this topic since it deals with the ethics of experimenting on human life. It all comes down to whether or not it is ethical to be taking stem cells from embryos, which are "babies" to many others who are anti-supporters to this idea.
The fear of transplanting these organs and having failure seem to be a major issue among the human population as they plan on transplanting among the younger generations rather than old. This is unethically fair to be choosing segregated groups, how would that be fair at all if everyone is in need of an organ transplant, yet the old has been selectively chosen to die while the young shall propser? On the other side of this argument, transplanted 3D organs need to be in younger bodies as they do need time to grow and develop, which they can't in elderly bodies. Therefore, would transplanting them into the elderly even worth the time and money?
Save the Young; Ignore the Old
Ethical Technology?
The thought of printing organs itself is quite questionable in the field of ethics indeed. Just imagine printers printing out the organs you need as if they're just printing out a research paper. It's as if it comes right out of a science fiction book. This is ethical as many people start to question, "Is this right? Printing out organs? Has technology gone TOO far?" Maybe technology has advanced too far with this type of breakthrough and it needs to stop here before the moral boundaries would be broken by scientists. However this technology is considered to be helping people and not harming them.
