Sandvik and research partners have successfully 3D printed tungsten carbide-cobalt using hot-wire laser irradiation, reaching hardness levels above 1400 HV. By utilizing a pre-heated wire and nickel-based interlayer, this process eliminates the cracking and defects typical of traditional melting. The method creates parts twice as tough as hardened steel while drastically reducing waste of expensive raw materials. This advancement allows for the additive production of complex, mission-critical tools that were previously impossible to manufacture efficiently. 🛠️ ⚙️ #additivemanufacturing #3dprinting #sandvik #engineering #materialscience
