Description This data set consists of simultaneous X-ray and infrared (IR) imaging of laser powder bed fusion of Ti-6Al-4V powder. Fifteen experimental runs were performed at different scan speeds, power levels, and numbers of passes to investigate porosity formation in real time and correlate it to the IR signature of the top surface. Details of the experiment are provided in the accompanying publication by the same authors [1]. The raw IR data is not provided for runs 12 and 15 because it is being used in an ongoing study.
