Three-dimensional printing has changed the track engineers are taking toward man-made living tissue. One example is this “bionic ear” produced by researchers at Princeton University. Using additive layering, they formed a scaffold of hydrogel polymer to support a cartilage of calf cells, and then added a silver-nanoparticle antenna to precisely mimic the human ear’s topology. Best of all, the ear gives the wearer the ability to hear frequencies well beyond those normally accessible to humans.
