Abstract
Official abstract text for this publication.
A method for manufacturing an additively-manufactured object, includes: an additively-manufacturing step of building a layered body by depositing a weld bead obtained by melting and solidifying a filler metal, the layered body having an opening along a forming direction of the weld bead and an internal space surrounded by the weld bead; and a closing step of forming a closing wall portion connecting an edge portion of the opening with the weld bead for closing. In the additively-manufacturing step, the opening is formed with a width dimension larger than a bead width of the weld bead, and in the closing step, the closing wall portion having a width dimension larger than the bead width is formed by the weld bead to close the opening.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing an additively-manufactured object, comprising: an additively-manufacturing step of building a layered body by depositing a plurality of weld beads obtained by melting and solidifying a filler metal, the layered body having an opening along a forming direction of a first weld bead of the plurality of weld beads and an internal space surrounded by the plurality of weld beads; and a closing step of forming a closing wall portion connecting an edge portion of the opening with a second weld bead of the plurality of weld beads for closing, wherein in the additively-manufacturing step, at least a third weld bead of the plurality of weld beads is deposited on a base to build side wall portions facing each other, multiple weld beads of the plurality of weld beads having different width dimensions are deposited laterally from an upper end of a side portion of the side wall portions to build a connecting wall portion having the opening, the edge portion of the opening on the connecting wall portion is built by depositing a narrow weld bead of the plurality of weld beads having a bead width smaller than a bead width of another weld bead of the plurality of weld beads that builds another portion, and the opening is formed with a width dimension larger than a bead width of the second weld bead, and in the closing step, and the closing wall portion having a width dimension larger than the bead width of the second weld bead is formed by the second weld bead to close the opening. 2. The method for manufacturing an additively-manufactured object according to claim 1 , wherein in the closing step, a torch for forming the weld bead is weaved to form the closing wall portion. 3. An additively-manufactured object, comprising: a layered body formed by depositing a weld bead obtained by melting and solidifying a filler metal, the layered body having an opening along a forming direction of the weld bead and has an internal space surrounded by the weld bead; and a closing wall portion configured to close the opening, wherein the opening has a width dimension larger than a bead width of the weld bead, and the closing wall portion is formed from the weld bead and has a width dimension larger than the bead width of the weld bead.
