A three-dimensional additive manufacturing device which can construct a shaped object by using a plurality of types of metal powder, a three-dimensional additive manufacturing system, and a three-dimensional additive manufacturing method are provided. A three-dimensional additive manufacturing device 100 includes a stage 4, a beam irradiation portion 8, a storage portion 42, a control portion 40, and a powder supply unit. The powder supply unit has a plurality of powder accommodating portions accommodating a plurality of types of metal powder and discharging the plurality of types of metal powder to the stage 4 and a holding mechanism for holding a plurality of powder accommodating portions and spreads the plurality of types of metal powder on the stage 4. The control portion 40 controls the powder supply unit so as to spread the plurality of types of metal powder on the stage 4 and controls the beam irradiation portion 8 so as to emit a charged particle beam with an output according to each metal powder on the basis of beam control data 64 read out of the storage portion 42. |
