Miniature organs are meant to be built smaller than their natural counterpart organ and perform the most vital function of that particular organ. For instance, the pancreatic organ produces insulin; therefore the purpose of the miniature, 3D printed organ is to secrete insulin into the bloodstream. This could help a patient with diabetes whose pancreas does not function properly. The purpose of in-situ printing is to print an organ directly into the human body during surgery. This technology could be used to replace organs that are damaged and cannot repair themselves (Ozbolat and Yu 2013). Both of these medical advancements would drastically improve human health and aid with the problem of organ shortages.
