What is Hot-Wire Laser Cemented Carbide Printing?

Hot-Wire Laser Cemented Carbide Printing is a directed-energy-deposition additive manufacturing process that combines a laser beam with a resistively preheated filler wire to build up tungsten carbide-cobalt cemented carbide parts layer by layer. By softening rather than fully melting the wire and substrate, the technique limits carbide decomposition and porosity, producing dense, hard structures directly from wire feedstock instead of powder.
