3-D printing method used to create human cartilage

from Design News

A scientist at the University of Pittsburgh has achieved a breakthrough in the quest to create artificial cartilage with human cells for treatment of degenerative joint disease and other joint-related health issues. "We used projection stereolithography, which uses sequential, layer-by-layer photo crosslinking to fabricate a 3-D structure. By using photo-activatable natural polymers derived from native extracellular matrix, cells may be loaded in the solution, and are then encapsulated in the final hydrogel construct ... [which] is viscoelastic, resembling native cartilage." more
