A duck found without a foot shortly after it hatched is waddling again thanks to a prosthetic leg designed by young scientists.
The 14 and 15-year-old students at Armorel High School in northeastern Arkansas used a 3D printer to create a new foot for the eight-month-old Indian runner duck named Peg.
His owner, Patsy Smith, told TV station KAIT that when she found the bird a turtle had apparently chewed off his foot.
"I was just elated. And it’s been a wonderful learning experience," she said of the students’ desire to help after hearing about Peg’s ordeal.
The school’s lab director, Alicia Bell, said it took around 30 attempts before pupils Matthew Cook, Darshan Patel and Abby Simmons created a model that was appropriate for Peg.
"The very first model, it was not very good, but that was what we were learning. And so from where it is now it is a completely different process," she said.
Ms Smith added: "Not only is it heartwarming, but it’s exciting.
"I’m just so grateful that there are people that truly care, and they’ve gone out of their way to do everything they can to make it as comfortable for the duck."
Last month, a puppy in California attacked by another dog was given a new lease of life thanks to a custom-made 3D-printed face mask.
In Thailand, a dog who had his two front paws chopped off was able to run again after a vet replaced his missing feet with blades.
