Scientists figure out how to 3D print Earth’s hardest metal

One of the toughest materials on Earth has had an equally tough manufacturing problem. It is so incredibly hard that making anything from it is expensive, wasteful, and a bit of a nightmare. Now, researchers think they have found a workaround. Scientists have successfully 3D printed tungsten carbide-cobalt (WC-Co), an industrial material prized for its […] Read the original article here: Scientists figure out how to 3D print Earth’s hardest metal One of the toughest materials on Earth has had an equally tough manufacturing problem.
