Derby the dog was born with deformed front legs that have made it difficult for him to walk. run and play.

However, the technology of 3-D printing has changed Derby’s life as the system has allowed for the creation of prosthetics for the dog, helping him run and jump around like a normal puppy.

Tara Anderson, who works for the company 3D systems, reportedly thought to make custom prosthetics with the 3-D technology rather than have Derby use traditional prosthetics for his deformed front legs, according to the Washington Post.

Derby wears his “elbow cups,” which are his custom made prosthetics, to run with his new owners, according to KTVU.

“The first time he was put on the prosthetics and he took off running he was just so happy. I was absolutely amazed,” stated Sherry Portanova, one of Derby’s new adoptive owners.

Anderson and the team at 3D Systems reportedly began the process of constructing prosthetics for Derby using CAT scans of the puppy’s front legs and MultiJet printing.

“He runs with [my wife] and I every day, at least two to three miles. When I saw him sprinting like that on his new legs, it was just amazing,” Dom Portanova said in a statement.

News of 3-D printed prosthetics has reportedly caused quite a bit of buzz in the market for human artificial limbs for kids. Although 3-D printed prosthetics have yet to be perfect, it’s still reportedly much cheaper than traditional methods.

The scans of the patient’s anatomy can reportedly be loaded into a computer and saved so kids won’t have to get a new mold every time they grow either.
