(PhysOrg.com) -- The range of uses for three-dimensional printers is increasing all the time, but now scientists are developing 3D "bioprinters" that will be able to print out skin, cartilage, bone, and other body parts.
3D printers print by depositing material line by line and then vertically layer by layer. They have been used to make sculptures and repair sculptures, to make three-dimensional objects out of plastics and polymers, and even to print food.
Professor James Yoo, from the Institute of Regenerative Medicine at Wake Forest University in Winston-Salem, North Carolina told the annual meeting of the American Association for the Advancement of Science (AAAS) his group is developing a system that will allow them to print skin directly onto burn wounds.
