image: This is a top-down view of a model of the human brain 3-D-bioprinted using alginate to show the ability to recreate the complex surface structures. Though there are no cells in this, and it is shrunk to only 1 inch in size, it shows the ability to take an MRI image of the brain and use the 3-D printer to create biomimetic structures. 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
