Additive manufacturing techniques for WC−Co cemented carbides: Principle, progress, and perspective

• AM enables fabrication of complex-shaped WC−Co cemented carbide products, overcoming limitations of traditional powder metallurgy. • AM techniques for WC−Co are classified into direct (DAM) and indirect (IDAM) categories based on post-processing steps. • Indirect AM, particularly binder jet printing (BJP), is identified as the most suitable route for achieving controllable microstructure. • The review covers principles, progress, and future perspectives of AM in WC−Co cemented carbides.
