金属粉末光造形複合加工技術による金型の製作―金属粉末の熱伝導率の測定―

抄録

The thermal conductivity of metal powder which is used for additive manufacturing is investigated theoretically and experimentally. The theory of instantaneous point source of heat is used to derive the equation to calculate the thermal conductivity of metal powder. Using this equation, the thermal conductivity of chromium molybdenum steel, copper, and nickel powders are obtained experimentally.
