| Abstract Scope |
While the benefits of on-demand manufacturing, enabled by additive manufacturing (AM), are clear, there are several qualification challenges that arise to ensure material/part reliability and mission success. Paramount to the deployment of AM systems abroad is the ability to demonstrate equivalency, not only across similar platforms but also across disparate machine manufacturers and sizes. NCAME is leading exciting research to develop a rapid and reliable approach for material and process qualification across different OEM platforms. Process equivalency is established through rigorous analysis of the process-structure relationships, integrating the thermal history as influenced by part size, location, and orientation. Process quality is interrogated through characterization of both micro- and defect-structure, iterating through the established workflow until the characteristics, i.e. defects and/or microstructure are deemed equivalent. Process equivalency is validated by assessment of the mechanical performance, including tensile and fatigue, encompassing different surface conditions (as-built & machined) and orientations (vertical & diagonal). |
