Scientists just 3D printed one of the hardest metals on Earth
Researchers have successfully used 3D printing, or additive manufacturing, to produce tungsten carbide-cobalt, a material known for its extreme hardness. This new method aims to reduce the high costs and material waste associated with traditional powder metallurgy.
Tungsten carbide-cobalt (WC-Co) is valued because it can withstand intense wear, pressure, and repeated use. That exceptional hardness makes it ideal for industrial tools, but it also creates a major manufacturing challenge. The material is difficult to shape, expensive to produce, and often requires more raw material than ultimately ends up in the finished component.
