| Abstract Scope |
The process instabilities intrinsic to the localized laser-powder bed interaction cause the formation of various defects in laser powder bed fusion (LPBF) additive manufacturing process. In this talk, I will first present our research on revealing the process instabilities by in-situ high-speed high-energy synchrotron x-ray imaging and diffraction. Then, I will introduce the defects mitigation approaches we developed based on the new mechanisms we discovered and the new insights we obtained from the in-situ characterization study for achieving defect lean metal additive manufacturing. |
