Researchers Achieve 3D Printing of Cemented Carbides Using Hot-Wire Laser Irradiation

Researchers developed an additive manufacturing approach using hot-wire laser irradiation to 3D print cemented carbides -- among the hardest metals on Earth -- achieving hardness levels above 1400 HV without defects or material breakdown. The technique reduces waste and production costs compared to traditional sintering, with potential applications in cutting tools, mining equipment, and defense manufacturing.
