This study deals with the thermophysical properties in the metal powder for additive manufacturing (AM). The thermal conductivity and the laser absorption of SKD61 powder were examined in order to clarify the suitable SKD61 powder for AM. As results, the thermal conductivity of SKD61 powder was influenced by the ratio of particle size rather than the average particle diameter. The thermal conductivity was the principal parameter to affect the building of metal powder, and the atmospheres during the building also have to be considered for the optimization of building conditions. In contrast, the laser absorption of SKD61 powder was not influenced to the average particle diameter and the classification.
