Additive manufacturing, or 3D printing, has drastically improved the uniformity and speed of metal parts manufacturing, but the printed parts are often plagued with defects, such as pores, that limit their performance. The process also requires an inspection of each part after printing, which can slow down production and limit where parts can be made.
