3D Printed Paws Give Derby New Leash on Life

Here’s a bit of beautiful news to wake up to on a Tuesday: 3D printing has been used to increase the quality of life of an adorable, disabled puppy dog.  In a recent video spot and Buzzfeed article, 3D Systems Director of ColorJet Printing Product Management, Tara Anderson, relays the story of a dog named Derby.  Born with deformities in both of his front legs, Derby was able to run again thanks to a unique pair of 3D printed prosthesis.

Anderson explains that the curved design is meant to give Derby traction, while preventing him from digging and getting caught in the dirt below his new feet.

Derby was eventually adopted by Sherry and Dom Portanova, who say that his new legs allow him to run even faster than them, up to 2 to 3 miles a day.

We’ve covered a lot of stories in which 3D printing has helped animals gain an improved quality of life, from Buttercup the Duck’s 3D printed prosthetic foot to the stories from North Carolina State University.  But, I have to say, this is one of the cutest applications of 3D printing yet.  Either that, or I just really want a puppy.
