Cemented carbides are commonly used for cutting tool applications with WC-Co being the prime example owing to its high hardness and abrasion resistance provided by WC and toughness provided by the ductile Co matrix. Conventionally these parts are fabricated via sintering and hot isostatic pressing. This typically means that the complexity of the part is limited. With the advance in binder jet additive manufacturing (AM), more complex shapes can be printed. In the present work, WC powders were printed using binder jet AM following which two different infiltration routines were used. The first approach involved heating the printed WC preform along with Co pellets to 1550oC to promote infiltration. The second approach relied on partial sintering of WC preform followed by Co infiltration. The results on these studies will be presented in detail.
