This duck is so high-tech, he even has a Facebook pageIn this story, Buttercup is a duck (not a princess...). Sadly, Buttercup was born with its left foot turned backwards, which prevented it from walking properly and caused him great pain. Enter our hero, Mike Garey of Feathered Angels Waterfowl Sanctuary. He adopted Buttercup and decided to do something to stop the pain and bring the duck back to as close to a normal life as possible.
With the help of NovaCopy, a 3D modelling company that donated its services, he was able to create a brand new foot for Buttercup!
Because the foot needs to be flexible, the usual plastics used in 3D printing aren't viable. Instead, NovaCopy printed a mould, which will be used to cast a silicone foot for the lucky duck, creating several iterations of the design to come up with the perfect one. It will be attached to his foot via a silicone sheath. (source)
