Abstract
The present invention relates to a powder for three-dimensional printing of a cermet or a cemented carbide body. The powder has 30-70 vol % of the particles that are <10 μm in diameter. The present invention also relates to a method of making a cermet or cemented carbide body. The method includes the steps of forming the powder, 3D printing a body using the powder together with a printing binder to form a 3D printed cermet or cemented carbide green body and subsequently sintering the green body to form a cermet or cemented carbide body.
