Symposium Multi-material Additive Manufacturing: Processing and Materials Design
Presentation Title Developing Functionally Graded Metals through Additive Manufacturing: Progress, Challenges, and Future Vision for a Unique Technology

On-Site Speaker (Planned) Douglas C Hofmann
Abstract Scope Functionally graded metals or “gradient alloys” have the potential to add a completely new dimension to metal additive manufacturing by allowing the composition of near net-shaped parts to be strategically controlled. NASA JPL/Caltech has been working towards both the design of alloys and the manufacturing of relevant spacecraft parts using this strategy for the past eight years. The current talk presents an overview of the vision for functionally graded alloys, including successful demonstrations of applications, but also discusses the challenges and paths forward for the research area. Emerging metal additive manufacturing technologies that are more conducive to functionally grading metals will be discussed, along with comments about the intersection between metal printing and metal coating.
