METHOD OF MAKING A POWDER FOR ADDITIVE MANUFACTURING
A method of making a ready-to-print cermet or cemented carbide powder of sintered granules includes the step of sintering the granules in a carburizing atmosphere. Due to the carburizing atmosphere, the granules will have less binder phase on the surface and will not sinter together and will be easy to deagglomerate and the granules will maintain its spherical shape. A powder made according to the method, as well as the use of the powder in an additive manufacturing process is provided.
