PROBLEM TO BE SOLVED: To provide a three-dimensional molded article having an accurate shape by an apparatus and a method capable of irradiating only a desired shape region with thermal energy.SOLUTION: A three-dimensional formation apparatus 1000 includes: a stage 120; material supply means 200 for arranging a green sheet 300 that is prepared by compacting a kneaded sintering material comprising metal powder and a binder into a sheet; first heating means for supplying first energy L1 to dissipate a part of the green sheet 300; second heating means for supplying second energy L2 to sinter a part of the green sheet 300; and drive means for allowing the first heating means and the second heating means to relatively and three-dimensionally move to the stage 120. The first energy L1 is supplied from the first heating means to the green sheet 300 to enclose a sintering region of the green sheet 300 supplied onto the stage 120, to be sintered by the second energy L2 supplied from the second heating means.SELECTED DRAWING: Figure 1 |
