| Abstract Scope |
Effective quality control of metal additive manufactured (AM) parts is indispensable to assure their structural integrity and performance. Offline inspection and characterization are essential tools in assessing quality of metal AM parts, but they do not provide a direct insight into structural development in a dynamic rapid solidification process. This research work emphasizes the development of real-time, insitu sub-surface and bulk structural analysis of AM parts during fabrication with various insitu-sensors. 316L SS metal parts were fabricated using direct energy deposition (DED) technique with integrated multi-sensors and in-line 2D X-ray diffraction tool for real-time process monitoring and structural analysis. This real-time process and structural data were correlated with printing process parameters and data from micro-computed tomography (CT), microscopy and mechanical properties of fabricated parts. This work's outcome can bridge the critical knowledge gap between process conditions and structure and ensure AM parts are produced with minimal defects and desired properties. |
