| Abstract Scope |
Surfaces of components fabricated using additive manufacturing (AM) often have a more complex surface than those built using conventional methods. In addition to the layered nature of the surfaces, there are features of the AM surface such as adhered powder or spatter particles which may not influence the mechanical performance of a component but will influence surface roughness metrics. A better understanding of measurement techniques, as well as how surface features influence surface roughness metrics is needed to improve the characterization and understanding of AM surfaces. The surfaces of specimens built using laser powder bed fusion (LPBF) AM from multiple standard materials such as nickel superalloys, steels, and aluminum are measured using several non-destructive techniques. Relationships between measurement techniques, measurement post-processing, and surface roughness will be discussed. An increased understanding of surface measurement techniques will inform future studies to determine parameter and properties relationships to surface roughness of AM components. |
