According to Yahoo, Derby the Dog was born with deformed front legs. Thanks to 3D-printed prosthetic legs, he is now able to run for the first time. Derrick Campana, a leader in the 3D printing company 3D Systems, has been working for years to further revolutionize 3D printing. He normally only developed prosthetics for humans until about 10 years ago. He then created the company Animal Ortho Care in Chantilly, VA, which is one of the first companies to make prosthetics for animals. Today, his company is one of five in the world that help animals with prosthetics, seeing 200 to 300 animals per month. However, Campana found Derby to be the perfect candidate to try out 3D-printed prosthetics for the first time. He molded a fiberglass cast and scanned that into the 3D printing system. Derby the Dog has now become the first animal to have successful 3D-printed prosthetics.
