3D printing allows for the layer-by-layer construction of a particular organ structure to form a cell scaffold. This can be followed by the process of cell seeding in which cells of interest are pipetted directly onto the scaffold structure. Additionally the process of integrating cells into the printable material itself instead of performing seeding afterwards.
Many people go on an very long waiting list for organ transplant!! yes a long waiting for right donor!! Many people die because of the long waiting list.
Well we may soon have organ printing and stem cells as answer to the problem.

3-D printing organs
Well they say in about 15 years from now we may have organ printed in lab for every organ of the human body for transplant.
