A dog running for the first time in his life thanks to 3D-printed prosthetic(假肢)legs has moved a lot of people． 

Derby was born with disabled front legs．While 3D printers have been used to make  replacement limbs(肢体)for humans，Derby is the first animal to be successfully equipped with 3D—printed prosthetics．

Derrick Campana，who helped create Derby’s new legs with designers at the 3D printing  company 3D Systems，has been an expert in that field for the past decade．He specializes in  the creation and use of corrective braces(矫正支架)and man-made limbs．Campana had  worked only with human patients until about 10 years ago．But when a pet fan brought a dog in  need of a prosthesis to him，he discovered he could apply the same technology that he’d  mastered on people to help animals．He also soon learned there was a market for animal  prosthetics and orthotics(矫正术)that hadn’t really been explored，so Campana founded Animal Ortho Care，one of the first companies to make orthotics and prosthetics specifically for animals．Today，Animal Ortho Care is one of five such companies in the world，seeing between 200 and 300 animal patients each month．

“We were really interested in helping Derby，”said Campana．Though 3D printing  technology．has been available for a while，he explained，some of the materials and tools that  work for making human prosthetics aren’t totally suitable for animals．For example，the  technology used to easily scan(扫描)a person’s leg is not as exact when scanning a leg  covered in fur．For Derby，Campana used a fiberglass cast(a special material)，and scanned  that into the 3D printing system．“In the future．hopefully we can just scan the leg directly．’’  he said．

Now that Derby can run，Campana said he is very excited about the good news．More than  three million people on the Internet have watched the video of Derby running on prosthetics．
