Design for Additive Manufacturing of Cellular Structures

AbstractAdditive Manufacturing technologies enable the fabrication of parts and devices that are geometrically complex, have graded material compositions, and can be customized. To take advantage of these capabilities, it is important to assist designers in exploring unexplored regions of design spaces. This paper explores the opportunities and challenges in design for additive manufacturing. A new computer-aided design for additive manufacturing (DFAM) method is presented that is based on the process-structure-property-behavior model common in the materials design community. Examples of cellular materials design and manufacturing are used to illustrate the DFAM method.
