Abstract
Additive manufacturing is a promising alternative to conventional fabrication processes and has direct applications to automotive, aerospace, medical, and other industries. Multi-material manufacturing, sustainability, component functionalization, and flexibility are some of its benefits. However, microscopic, macroscopic, and functional properties of the fabricated parts are not well understood in terms of materials and process parameters. In this paper, we present our efforts in the development of Digital Holographic Interferometry (DHI) and Digital Image Correlation (DIC) methodologies for characterization of specific additive manufactured components. When used in parallel, DHI and DIC offer the complementing advantages of high spatial and temporal resolutions ranging from nanometers to millimeters and from nanoseconds to seconds, respectively. Representative results illustrating the complementing capabilities of DHI and DIC are presented, including high-speed measurements (ie, 20 kHz or more) of transient response (high and low deformations) of additive and conventionally manufactured components. Results highlight the effectiveness of both optical method to enable quantitative and qualitative nondestructive characterization of final products.
