Abstract: A metal additive manufacturing technique is provided to improve various characteristics by irradiation of a pulse laser without disposing a transparent medium. A metal additive manufacturing device includes: a material supply source configured to supply a material to be deposited; a heat source configured to melt the material by outputting an energy beam; a moving driver configured to scan at least the energy beam; and a laser irradiator configured to irradiate a solidified portion of the material in a temperature lowering process with a pulse laser.
