PROBLEM TO BE SOLVED: To provide a configuration of a three-dimensional molding method so as not to cause trouble in travelling of a powder feeding blade even when a protruding sintered part is generated in a narrow sintered region.SOLUTION: In a three-dimensional molding method, a fine sintered region 11 in which any one of a cross-sectional area or an average diameter in a horizontal direction, a molding width, and an undercut angle at an end part is a prescribed quantity or less, is pre-stored by a control system, or determined by the control system in a sintering step, and if a protruding sintered part 12 is formed above the sintered region 11, all or part of the protruding sintered part 12 is cut off by a rotary cutting tool 3, and thereby no trouble in travelling of a powder feeding blade 2 occurs.SELECTED DRAWING: Figure 10 |
