Derby the dog has a birth defect that renders his front legs mostly useless. After his original owners surrendered him, animal-rescue organization Peace and Paws took him in, and that’s where he caught the attention of Tara Anderson.
Anderson is the director of CJP product management for 3D Systems, a company that specializes in 3-D printing and prototyping, and when a cart didn’t work well enough for the dog’s needs, Derby received some custom-made, 3D-printed prosthetics. The team decided that spring-like “running man” limbs would get stuck in the ground, so Derby’s new legs are rounded for maximum mobility and comfort.
