Zusammenfassung: | Provided are a method for producing a molded article with which it is possible to mold a molded article by efficiently forming weld beads without producing defects such as sagging and humping, a production device, and a molded article. In this method for producing a molded article, a filler material is melted and solidified, a weld bead is formed on a base surface along the trajectory of a torch, and a molded article is formed by the weld bead. At such time, the molded article has a bead formation portion at which the influence of gravity is strongest, and a support bead that has higher viscosity during production of the weld bead than does the weld bead is formed on the bead formation portion. Another weld bead is then formed so as to overlap the support bead. |
