Abstract:

Metal binder jet 3D printing is suitable for fabricating metal parts in small quantity and many varieties in a short period of time. Fine powders for metal injection molding are used for binder jet 3D printer. Powders need to flow during recoating to the powder bed, and also after that they need to show high density for enough strength of green parts for handling. In this study, powder characteristics for binder jet 3D printing is focused, and effect of distance between powders on the printing and sintering properties of metal binder jet 3D printing is clarified.
