Size, size distributions, and morphologies of metal powders used for additive manufacturing are some of the key parameters determining the quality of produced part. Virgin and recycled Ti6Al4V and Ni 718 alloys were investigated using high energy x-rays. High energy x-rays allow for rapid characterization of size and size distributions in a statistically meaningful manner. Further, x-ray tomography technique was used to perform 3D-characterization of powder particles to establish their 3D shapes and their internal porosity. Data from virgin and recycled powders were compared to understand the changes in the powder quality with the number of recycling runs and its potential impact on the part builds.
