Probably the best measure of a technology’s value is whether it can be used to improve the lives of awesome dogs. And in that light, 3D printing just scored a major, heartwarming victory.

Below, you’ll meet Derby, a sweet pooch born with deformed legs. Though he was able to get around with the help of a wheeled cart, Tara Anderson, a director of project management at 3D Systems, knew her company could provide him and his owners with a less cumbersome solution. Still, nobody was prepared for how much he’d love his new prosthetics.

Now that he’s running a few miles a day, Derby’s living up to his name—we’d bet on him to win any race by a cold, wet nose.
