3D bioprinting techniques allow intricate living structures to be printed with multiple cell types arranged in layers, like various human tissues and organs. This document discusses how 3D printing could be used to print models of organs like kidneys, bone and muscle by co-printing biological materials in three dimensions. In the future, 3D bioprinting may help address organ shortages by printing transplantable organs using a patient's own cells, reducing rejection risks and transplant waiting lists while saving lives. However, many challenges like developing vascular systems and controlling organ quality and costs during bioprinting still remain.

6. Conclusion
Printers are now printing ribbons of tissue from your
cells to a dish. Improving your chances at recover
large amount of dead, missing or diseased tissue.
Although still a decade or more away, human hearts
and other organs available for transplants. Reduce
the amount deaths of people on the transplant lists,
of all ages. Little or no more rejection because it
was made from your cells. Little or no need for
continue anti rejection medicine. The possibilities
from stem cell research.
