This study aims to design and fabricate a lightweight, high-strength, low-cost and easily accessible 3D printed below-knee prosthetic leg without support material to improve the quality of life of amputees. First, a flexible and jointless one-piece below-knee prosthetic leg model was designed by considering the anthropometric data of children who frequently require prosthetics.
