dc.description.abstractAdditively Manufactured (AM) metals have the possibility of revolutionizing in-situ manufacturing by allowing large or complex components to be quickly and easily manufactured, where access to manufacturing would be otherwise difficult or impossible. AM processes do not require the tooling, fixturing, nor skill required of traditional machining processes. The United States Navy has identified Additive Manufacturing as a technology of interest to provide an alternative means of manufacturing components for rapid deployment in forward operating locations. While AM technology has significantly improved since it's conception, clearly defined standards for the approval of a component to be placed in-service do not yet exist or are not clearly defined for US Navy use. Furthermore, the issue of repeatability between components manufactured in different prints or at different printing sites continues to be an area of concern with AM processes. To meet these requirements, this work addresses issues of repeatability for components manufactured using 17-4PH SS and provides analysis to determine metrics of repeatability between components manufactured at different print sites. Analysis of various geometries printed in 17-4PH Stainless Steel, including angular and thin structures is undertaken. Photogrammetric analysis will be employed to verify the geometric accuracy of printed structures. Non-destructive evaluation (NDE) methods including Vickers Microhardness and Surface Roughness are employed to evaluate repeatability. More rigorous laboratory testing, including tensile testing and microstructural evaluation will be conducted for the purpose of comparison to NDE methods.
