This 3D printer could one day make new body parts for transplant patients

According to Cleveland Clinic, 21 people in the US die waiting for an organ every day. Data from states that 2,741,336 people in the US are currently awaiting organ transplants, some even waiting for a heart or lung.

However, Swedish startup Cellink may soon have the answer — using a simple 3D printer and a special gel, the company has found a way to make skin, ears, liver cells, and can even replicate fully functional cancer tumors that can then be used to develop new cancer treatments.

Researchers, led by Itedale Namro Redwan, found that just the right combination of synthetic and natural polymers, blended with materials such as those based on ECM (extracellular matrix) could possibly serve as a perfect environment in which to build new organs and reproduce all sorts of cells.
