Real-time monitoring of laser powder bed fusion process using high-speed X-ray imaging and diffraction

Abstract We employ the high-speed synchrotron hard X-ray imaging and diffraction techniques to monitor the laser powder bed fusion (LPBF) process of Ti-6Al-4V in situ and in real time. We demonstrate that many scientifically and technologically significant phenomena in LPBF, including melt pool dyna...
