Understanding the Reusability of Ti6Al4V Powder in Laser Powder Bed Fusion. [PDF]
Eng Sci Addit ManufThis study aimed to determine the effects of how powder degrades in quality from use in the laser powder bed fusion process and investigate what changes in the powder cause defects in finished parts. It was determined that the reused powder affected the finished part quality, resulting in an increased number of lack-of-fusion pores.
