Topic title:

Design for Additive Manufacturing

Abstract:

Additive manufacturing (AM) is an important digital manufacturing technology leading to Industry 4.0 processes. Its digital input enables great flexibility and adaptability to changing markets, lot-size-of-1 and mass customization, and little if any lead-time since no hard tooling is needed. Designing products and parts to take advantages of these AM characteristics is key to realizing the benefits of AM. In this talk, I discuss the principles of design for AM, the importance of considering the entire manufacturing process chain when designing parts, and the large benefits achievable when exploring new product architectures. Implications for design for AM from emerging materials are explored also. Examples taken from industrial and biomedical applications illustrate the design concepts.
