A service learning project where students learn and apply advanced CAD modeling techniques to the development of a parametric, fully customizable CAD assembly of prosthetic limbs is described. Engineering students, working with engineering faculty, designed and built prosthetic arms and hands using 3D printing for children in need within the local community. While existing CAD designs are available, customizing them to the very unique anatomy of users with missing or malformed upper extremities is a challenging process. One of the goals of this project was to streamline the customization process by customizing the prosthetic CAD models before the first part is printed. Top-down design is an advanced modeling approach that utilizes key parameters in a “skeleton” part to drive the size of all members of the prosthetic arm to greatly reduce customization time and allow nearly limitless customization. The educational goals of this project are to provide deep, applied learning of advanced CAD modeling (a key and broad mechanical engineering skill) techniques within the scope of a service learning project by harnessing the excitement and energy generated by this extracurricular project to amplify technical skill development. Project outcomes and perspectives from students and faculty are presented.
