Abstract

A method of manufacturing a three-dimensionally shaped object includes a first powder-layer forming process in which a first portion of at least one thickness determining member forms a powder layer by moving in contact with powder, a solidifying process in which a solidified portion is formed in the powder layer formed in the first powder-layer forming process, a second powder-layer forming process, performed after the solidifying process, in which a second portion of the at least one thickness determining member forms a powder layer by moving in contact with the powder, and a renewal process performed between the first powder-layer forming process and the second powder-layer forming process. In the renewal process, the portion having been in contact with the powder is renewed such that the second portion is different from the first portion.
