Abstract

Metal binder jet (BJT) 3D printing is suitable for fabricating metal parts in small to medium quantities and many varieties in a short period. Fine powders for metal injection molding (MIM) are used for binder jet 3D printers. In this study, powder characteristics for binder jet 3D printing are focused while comparing it to metal injection molding process. The effect of powder loading in the green compacts on debinding and sintering behavior is investigated. The green densities of the specimen fabricated by several processes were changed by powder loading, and it is clarified that the sintered density was determined by green density.
