3-D printing is becoming a huge new scientific fad, and I dearly hope to see it continue. Scientists at Cornell have now figured out a way to print the scaffolding for an ear using a 3-D printer. The printer creates a special mold which is then filled with collagen from rats' tails before cow ear cartilage is added. Within three months cartilage will have grown fully throughout the mold and a fully formed ear will be left in its place. This is a truly remarkable feat, one that has been a long time coming. Hopefully we will see more "printable" organs that will allow us to meet all organ transplant needs.
