Printing Simplified Anatomy in 3-D (4 of 9) (VIDEO)

American Association for the Advancement of Science (AAAS)

Caption

This video shows uniaxial strain of a FRESH printed femur model showing elastic recovery. A scaled-down human femur FRESH printed in alginate was uniaxially strained ~40% and exhibited elastic recovery. This demonstrated good mechanical strength within and between the layers of the print. This material relates to a paper that appeared in the Oct. 23, 2015, issue of Science, published by AAAS. The paper, by T.J. Hinton at Carnegie Mellon University in Pittsburgh, PA, and colleagues was titled, "Three-dimensional printing of complex biological structures by freeform reversible embedding of suspended hydrogels."
