Freeform Mechanical Design
Project Members: Jonathan Hiller
With the emerging capabilities of multi-material, freeform 3D printing, an exponentially increasing mechanical design space is available to engineers. Materials with a wide range of mechanical, electrical, thermal, and optical properties will soon be printed seamlessly together in full3D. Traditional CAD programs are inadequate to efficiently utilize this vast design potential. In this research, we develop a genetic algorithm to design freeform (smooth, unconstrained) shapes consisting of multiple materials (arranged arbitrarily) to meet high level functional goals. This includes something as simple as designing the stiffest, lightest brace for given loading and constraints, or something as complex as an integrated electromechanical device like a locomoting robot.
