Direct laser 3D printing of refractory materials such as silicon carbide (SiC), tungsten (W), and tantalum hafnium carbide (TaHfC) have been systematically investigated. High relative density has been achieved for SiC, SiC/Al, W, and W/TaHfC. High density SiC structures and W thin wall were also fabricated. By mixing the metal powders (e.g. Al or W) with ceramic powder such as SiC or TaHfC, a metal/ceramic matrix is formed during the direct laser melting process to tailor the mechanical properties.
