3-D-Printed Skin Leads the Way Toward Artificial Organs

Emotional, Burning, Unlimited Tuned Laboratory



Researchers claim that additive manufacturing can now produce functional skin, and the first internal organs may be ready within six years.
The initial hype surrounding 3-D printing may have started to fade, but researchers using the technique to create living tissue are showing encouraging results.

3-D printing parts of our anatomy is not a new idea. The basic premise: insert the correct cells into a polymer or gel, print them out into a 3-D structure, and then allow the cells to grow into a living entity. If such a feat can be achieved, it could provide a supply of organs for transplant patients and remove the need for donors.
