3D forming apparatus and a three-dimensional forming method

PROBLEM TO BE SOLVED: To provide a three-dimensional forming apparatus achieving high productivity by synchronizing and driving a plurality of energy supply means in a simple configuration.SOLUTION: A three-dimensional forming apparatus 1000 includes: a stage 120; material supply means for supplying a sintering target material prepared by kneading a metal powder and a binder to the stage 120; a head unit including an energy irradiation part 140 for supplying energy capable of sintering the sintering target material 300 to the sintering target material 300 supplied by the material supply means; and a head base 150 holding a plurality of the head units; and the three-dimensional forming apparatus also includes drive means to allow the head base 150 to relatively three-dimensionally move with respect to the stage 120.SELECTED DRAWING: Figure 1
