Roughly 5 in every 10000 children are born with congenital limb deficiencies. It has been shown that an early introduction of a prosthesis helps develop the motor function of children with limb deficiencies. However, there is a lack of infant-sized prosthesis that are affordable, durable, aesthetically pleasing, and provide functional support and gripping capabilities. Our project aims to use 3D printing to fabricate an infant prosthesis because of the wide range of materials which allows for a high factor of customization. Previous tests have shown that the device is capable of mimicking the gripping motion of an infant's hand and cost analysis have shown that the materials to fabricate one prosthesis is low. Once finalized, the low-cost hand would increase the accessibility of infant-sized prosthesis for those that need them, thus allowing an early introduction and incorporation of prosthetics into the child’s life.
