Hard materials keep modern life moving, from drill bits to cutting tools. One of the toughest is tungsten carbide with cobalt, often shortened to WC–Co. It lasts a long time and resists wear, but ...

Scientists have found a promising new way to manufacture one of industry’s toughest materials—tungsten carbide–cobalt—using advanced 3D printing. Normally, producing this ultra-hard material requires ...

The approach uses 3D printing to produce WC-Co cemented carbides - ultra-hard materials used in cutting and construction tools - while reducing the waste and cost of conventional manufacturing.
