Abstract

Official abstract text for this publication.

A method of manufacturing an additively manufactured object includes: checking, for an additively manufactured object including a plurality of internal passages, the presence or absence of a deposit in each inner wall surface of the plurality of internal passages; and selectively removing the deposit from the internal passage in which the deposit has been detected in the checking, among the plurality of internal passages.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method of manufacturing an additively manufactured object, the method comprising: checking, for an additively manufactured object including a plurality of internal passages, presence or absence of a deposit on an inner wall surface of each of the plurality of internal passages; and selectively removing the deposit from an internal passage in which the deposit has been detected in the checking, among the plurality of internal passages, wherein in the removing, the deposit on the inner wall surface of the internal passage is removed by performing electrical discharge machining using an electrode including a base portion covered with an insulating material and a tip portion exposed without being covered with the insulating material. 2. The method of manufacturing an additively manufactured object according to claim 1 , wherein each of the plurality of internal passages includes a bent portion. 3. The method of manufacturing an additively manufactured object according to claim 1 , wherein the deposit on the inner wall surface of the internal passage is removed by performing electrical discharge machining in a state in which at least a part of the base portion and the tip portion are inserted into the internal passage in which the deposit has been detected in the checking. 4. The method of manufacturing an additively manufactured object according to claim 1 , wherein the electrode is a deformable electrode. 5. The method of manufacturing an additively manufactured object according to claim 1 , wherein the electrode is an electrode formed by additive manufacturing. 6. The method of manufacturing an additively manufactured object according to claim 1 , wherein a portion of the electrode including the tip portion of the electrode has a curved shape.
