Abstract
A stress controlled layer is constituted to include a compressive stress applied part that is a region to which a compressive stress is applied and a compressive stress non-applied part that is a region different from the compressive stress applied part. In a solidifying step, scanning of a laser beam or an electron beam is performed while a scanning direction for the compressive stress applied part is different from a scanning direction for the compressive stress non-applied part such that the compressive stress applied part expands further than the compressive stress non-applied part or the compressive stress non-applied part shrinks compared with the compressive stress applied part based on a relationship between the scanning direction and an expansion quantity or a shrinkage quantity at a time of temperature change or at a time of heat treatment.
