| Abstract Scope |
Additive manufacturing (AM) has been revolutionizing part manufacturing, design optimization, sustainability, and new applications. Specifically, directed energy deposition (DED) enables the possibility of printing gradient alloys. Additively manufactured gradient alloy parts are manufactured with multiple fractions of dissimilar metals. In this work, we present the potential of using a combination of DED and laser powder bed fusion (L-PBF) to fabricate gradient alloy parts with superior device functional performance. The combined AM approach is used to manufacture high-temperature heat exchangers for concentrated solar power applications. By leveraging the unique capabilities of the combined technologies, it provides an opportunity to use lower cost materials such as stainless steel in lower temperature sections and higher temperature materials in other regions in the heat exchanger designs. The thermal-fluid modeling shall utilize its unique manufacturing processes to conduct topology optimization. This work is expected to support advancements in the AM area for various energy applications. |
