Abstract: Additive manufacturing (AM) today affords complete freedom in controlling geometric details and material composition in three-dimensional fabrication. They provide new routes for manufacturing parts with structural properties in high-strength, light-weight, and exceptional performance. To further the adoption of the AM technologies, there is a need for “Design for Additive Manufacturing” methodologies and computer tools that empower designers to realize products that can fully capitalize on the AM capabilities.
Our approach to Design for Additive Manufacturing is an optimization-driven methodology for design exploration, synthesis and multi-disciplinary optimization. Our primary development is a topology optimization method integrated with analysis models for optimal material design of functional components. The required material properties are achieved by optimizing the important factors governing void geometry and material distribution. It generates structurally optimal design concepts from supplied information on loads, constraints and required product performance and manufacture conditions. The method has found a wide range of applications in the design of multi-functional structures, auxetic materials, and light-weight aero-structures. The applications for cellular structures and shellular materials will be particularly discussed.
