Abstract Scope |
Additive manufacturing has the advantage of unrestricted geometry freedom, enabling complex structures and diverse material choices that are hard or impossible to achieve using conventional manufacturing techniques. With growing capability comes increased complexity and challenges. Hence it is vital to employ advanced characterization techniques that provide the most insights on structure and processing outcomes. X-ray computed tomography (CT) is a characterization technique that reveals structures without strict dimension restriction or sample preparation. By capturing inherently 3D data in a wide range of resolution, a comprehensive and sampling bias free understanding of structure can be achieved. The established knowledge by X-ray CT also provides concrete foundation for both ex situ and in situ correlation studies to be elevated from 2D into 3D space. This presentation demonstrates how X-ray CT can be used for AM structure characterization studies including quantification and spatial distribution of defects, microstructure evolution, as well as load simulation. |
