video: Out-of-plane FRESH printing of a helix is shown. An example of a FRESH printed helix in a continuous 3-D curve demonstrating that it is possible to print in true freeform space and that fabrication is not limited to planar, layer-by-layer approaches. 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." view more
