Technology is change the world in some really amazing ways. Look no further than the story of Derby, a dog who was born with deformed front legs that left him virtually immobile. He was originally confined to a cart, but a pair of 3-D printed legs freed him to run and play.
"This is what 3-D printing is all about. To be able to help anybody - dog, person, whoever - to have a better life. There's nothing better to be involved in," said Tara Anderson, a director at 3D-printing company 3D Systems. Anderson adopted Derby after hearing his story from Peace and Paws.
