ADDITIVE MANUFACTURING APPARATUS

Japanese Patent JP2022057039

A

To provide an additive manufacturing apparatus that can easily adjust control conditions for a heat-retention light beam irradiation device to obtain a high-quality additively manufactured product.SOLUTION: An additive manufacturing apparatus 100 comprises: a powder material supply device 110; a melting light beam irradiation device 121; a heat-retention light beam irradiation device 122; and a control device 130 that controls irradiation of a melting light beam MBM and a heat-retention light beam KBM so that a heat-retention light irradiation area KS, being an irradiation area to which the heat-retention light beam KBM is applied, superimposes a melting light irradiation area MS, being an irradiation area to which the melting light beam MBM is applied, to mold an additively manufactured product FF obtained by adding a powder material P to a base material B. The control device 130 prepares a process map PM that shows a relation between the size of heat-retention light power density KBP being light output of the heat-retention light beam KBM per unit area and the heat-retention light irradiation area KS, and quality of the additively manufactured product FF to control the irradiation of the heat-retention light beam KBM on the basis of the process map PM.SELECTED DRAWING: Figure 7
