Numerical insights on the spreading of practical 316 L stainless steel powder in SLM additive manufacturing

In powder bed additive manufacturing (3D printing), powder spreading plays a dominant role in determining not only the subsequent process but also the quality/performance of the printed part. Therefore, how to realize a superior powder bed with desired structure and property is of key significance a...
