Researchers Find a Way to 3D Print One of the Hardest Engineering Materials on Earth

A new manufacturing approach aims to reshape how one of industry’s hardest materials is made. Tungsten carbide-cobalt (WC–Co) sits behind many of the sharp, long-lasting tool edges that cut through metal, concrete, and rock. Its standout hardness is also its biggest manufacturing headache. Once this material is formed, it resists shaping so strongly that production […] Read More
