The idea of design for additive manufacturing is to explore new design spaces to take advantage of the unique capabilities of AM, while not violating any manufacturing constraints. In order to provide guidance to designers to achieve their objectives most effectively, computer-aided design tools are needed that are “AM aware;” that is, that have models of AM process capabilities and limitations. Furthermore, they should provide guidance on exploration of design concepts, particularly how to take advantage of the complex shape capabilities of AM. In this talk, we present a prototype CAD system that provides manufacturability feedback of designs, offers AM-specific design features, and supports lattice structure design and topology optimization. Design examples are used to illustrate CAD system capabilities. This project is funded in part by America Makes and involves 16 company and academic partners in the aerospace, energy, and automotive industries.
