Patent ID: 11345080

Abstract:
A method for manufacturing a three-dimensional shaped object includes: a first shaping step of forming a first layer in contact with a stage provided with a recessed portion by changing a relative position between a discharge unit and the stage while discharging a molten material from the discharge unit toward the stage; and a second shaping step of stacking one or more layers on the first layer by changing the relative position between the discharge unit and the stage while discharging the molten material from the discharge unit toward the first layer. The stage has a first region including a region on the recessed portion and a second region different from the first region, and in the first shaping step, the first layer is formed by making a first supply amount which is a supply amount of the molten material supplied from the discharge unit to the first region per unit area larger than a second supply amount which is a supply amount of the molten material supplied from the discharge unit to the second region per unit area.
