Scientists working on the Organovo NovoGen printer recently created the first "printed" human vein. This technology could replace other toxic and carbon-heavy medicinal practices like using artificial body parts in the human body.
The printer is meant to be used in regenerative medicine. Instead of borrowing body parts from someone else - or yourself - the printer will just make a new part for you. The printer is loaded with cartridges of "bio-ink" a substance that acts as a kind of scaffolding for the cells to retain their shape. A sophisticated computer is linked to the printed that is pre-programmed with the 3D blueprint of whatever is being made. The computer instructs the printer to lay down two dimensional layers of bio ink and cells that eventually form into the 3D body part. article taken from www.inhabitat.com
