Abstract
A method of producing a three-dimensionally shaped object includes a step of equipping an additive manufacturing apparatus with a plate, a step of forming a support portion by depositing raw material powder on the plate and radiating light, a step of forming a three-dimensionally shaped object by depositing raw material powder on the support portion and radiating light, and a step of separating the three-dimensionally shaped object from the support portion. In the step of forming the support portion, a low-density support portion and a high-density support portion are formed. The low-density support portion has a lower density than a three-dimensionally shaped portion formed in the step of forming the three-dimensionally shaped object. The high-density support portion has a higher density than the low-density support portion.
