Abstract Scope |
Characteristics of an additively manufactured part through powder bed processes (e.g., binder jetting, powder bed fusion) are well influenced by the attributes of the powder and powder spreading process. Previous studies compared the printed part from unimodal powder and bimodal powder and showed that bimodal powder improves part density. But the distribution of the bimodal powders and their effect on the powder bed and subsequently on printed part has not been fully understood. In this study, unimodal and bimodal powder were used to experimentally study the powder particle distribution and the powder bed surface contour in the powder bed generated from the spreading process. |
