Control method for three-dimensional additive manufacturing apparatus, control method for three-dimensional additive manufacturing apparatus, and control program for three-dimensional additive manufacturing apparatus

摘要

Improve modeling accuracy without finishing. A three-dimensional additive manufacturing apparatus, on a modeling table on which a three-dimensional additive object is formed, a material injection part that injects a material of the three-dimensional additive object, and a light irradiation part that irradiates the material with light. The material irradiated with the light beam is melted and solidified to cut a bead; the material sprayed by the material sprayed by the material; the light beam irradiated by the light beam irradiated by the light beam; and the cutting And a control unit that controls the cutting of the bead by the unit, and the cutting unit cuts the upper surface of the bead with a dimension that is less than the stacking height and is ½ or less of the bead thickness.
