| Abstract Scope |
Additive manufacturing (AM) is particularly well-suited to leverage the power of the Integrated Computational Materials Engineering (ICME) paradigm due to its inherent digital nature, starting with the initial computer-aided design (CAD) file through modern non-destructive evaluation (NDE) techniques of the final component. Additionally, AM exhibits an overlap across the material, process, and design aspects – each is intimately connected with the other two. Therefore, an AM-based digital thread offers unique control over processing parameters and the potential for tailoring material properties with high precision. However, the effective implementation of ICME within AM faces challenges related to verification, validation, and uncertainty quantification (VVUQ) as noted by recent programs at the Office of Naval Research (ONR). This presentation will focus on recent activities at ONR to address these challenges as it relates to reproducibility, qualification, design, and standards as well as the future outlook for technology development. |
