From an ethical standpoint, there are concerns with respect to the availability of organ printing technologies, the cell sources, and public expectations. Although this approach may be less expensive than traditional surgical transplantation, there is skepticism in regards to social availability of these 3D printed organs. Contemporary research has found that there is potential social stratification for the wealthier population to have access to this therapy while the general population remains on the organ registry. The cell sources mentioned previously also need to be considered. Organ printing can decrease or  eliminate animal studies and trials, but also raises questions on the ethical implications of autologous and allogenic sources. More specifically, studies have begun to examine future risks for humans undergoing experimental testing. Generally, this application can give rise to social, cultural, and religious differences, making it more difficult for worldwide integration and regulation. Overall, the ethical considerations of organ printing are similar to those of general ethics of bioprinting, but are extrapolated from tissue to organ. Altogether, organ printing possesses short- and long-term legal and ethical consequences that need to be considered before mainstream production can be feasible.
