Zusammenfassung:	To provide a technology for suppressing a decrease in strength of a molding in a manufacturing method of a molding.SOLUTION: A manufacturing method of a molding comprises a first step of forming a first molding layer on a base material by melting and solidifying a first metal powder, a second step of heating the first molding layer, and a third step of forming a second molding layer having a smaller coefficient of thermal expansion than the first molding layer. The third step forms the second molding layer on the heated first molding layer by melting and solidifying a second metal powder.SELECTED DRAWING: Figure 2 【課題】造形体の製造方法において、造形体の強度低下を抑制する技術を提供する。【解決手段】造形体の製造方法は、第１の金属粉末を溶融し凝固させることで、基材の上に第１造形層を形成する第１工程と、第１造形層を加熱する第２工程と、第１造形層よりも熱膨張係数が小さい第２造形層を形成する第３工程であって、第２の金属粉末を溶融し凝固させることで、加熱された第１造形層の上に第２造形層を形成する第３工程と、を備える。【選択図】図２
