Hiroshima University engineers created a precise 3D printing method for ultra-hard tungsten carbide–cobalt, enabling complex, durable parts for aerospace, construction, and medical use.
Engineers at Hiroshima University have developed a new 3D printing method for tungsten carbide–cobalt (WC–Co), a material harder than most steels, achieving over 1,400 on the Vickers hardness scale.
The technique uses pre-heated wire and laser irradiation without fully melting the metal, reducing waste and preserving structural integrity.
It enables precise, complex shapes for applications in aerospace, construction, and medical implants.
The study is set to be published in April 2026.
