P17061: e-NABLE Puppy Prosthetic


Project Summary Project Information

Prosthetic limbs are an emerging technology that have gone to amazing lengths to help those with limb loss to continue with everyday activities that most people take for granted. Whether it is a result of disease, congenital birth defect, or injury, someone with this disability has struggles performing the simplest of tasks. However, prosthetic limbs make it possible for people to continue living a more normal life, while also doing enjoyable activities that one would not be able to without this technology. Today, engineers, prosthetists, and doctors are constantly researching and experimenting to develop and improve all types of prosthetics. They can range from a simple design to complex and intricate systems working together to perform more “human-like” movements. Due to the high cost of prosthetics and the various replacements and time to manufacture, there are other quicker and cheaper methods being explored to create these limbs, such as 3D printing, a form of rapid prototyping.

RIT’s e-NABLE community volunteers to 3D print and donate prosthetic hands to children of all ages. There are several hand designs based on a child’s need and new designs are being developed constantly. These prosthetics are 3D printed using CAD software, 3D printers, and different types of plastic, such as ABS, PLA, and several others. The e-NABLE community has focused on helping children, but humans are not the only ones in need of prosthetics, thus expanding what e-NABLE can do in the future.

More recently, animals all over the world require the use of prosthetic limbs, and dogs are a large portion of that. A four-year-old German Shepherd-Lab Mix had her right hind leg amputated when she was a puppy due to neglect and injury. Daily activities are quite difficult for her due to only having three legs. Running at the park and taking walks are especially difficult due to extra pain in her compensating joints, while tiring quickly as well. She is missing a crucial part of her anatomy and this restrains her from living her life to her fullest potential.

While prosthetics have been used to help people, their assistance to animals continues to grow and could really be a great solution for this dog and additionally, for her owner. The goals for this project are to design and model, prototype several iterations, test and analyze, and 3D print the majority of a prosthetic leg for a dog so that she can perform all of the activities that every dog should be able to do with ease with hopes to improve the dog’s quality of life. This project will increase those that will be helped by e-NABLE, as well as expand the possibilities of 3D printing prosthetic limbs for animals.
