| Abstract Scope |
Additive manufacturing (AM) is transforming industries, but qualifying AM parts remains challenging due to the lengthy and costly nature of traditional mechanical testing. This is mainly due to the anisotropy and heterogeneity of AM materials from layer-wise deposition, localized thermal histories, and unique subsurface defects. These factors cause spatial variability in mechanical properties linked to process parameters and geometry. This work presents a micro-scale testing framework to assess local mechanical behavior in additively manufactured metals. Miniature tensile specimens (3 mm × 1 mm × 0.25 mm) from various AM regions are used to measure stiffness, yield strength, ultimate tensile strength, and strain-to-failure, and results are correlated with microstructure and thermal history. Capturing local variability supports more accurate structure–property–process relationships and enables creation of a global property matrix for lifetime prediction under different conditions. This method offers a rapid, efficient way to evaluate AM components and reduce qualification costs. |
