3D Printing Bone With a Doughy Substance

Dr. Jing Yang of the University of Nottingham says work on 3D printing human tissues for regenerative medical applications uses living cells and bio-materials placed at precise locations to mimic the natural organization of cells. These “engineered tissues” mimic their naturally-occurring counterparts in the body, and he and a team of researchers are now using a paste-like bone replacement material can be mixed at room temperature to repair fractured bone. Made of L-lactic-co-glycolic acid and polyethylene glycol, the material is injectable, can be mixed at room temperature and features a porosity which will allow it to hold a variety of chemicals which promote bone growth.

Below is a picture of the bone thats been 3D printed from this doughy substance:

This is very exciting. I can't wait to see the applications of this kind of bio-sculpting.
