US 2025/0083254 A1 · ADDITIVE MANUFACTURED OBJECT PRODUCTION METHOD, AND ADDITIVE MANUFACTURED OBJECT PRODUCTION SYSTEM

Abstract

An additive manufactured object production method includes: a core portion forming step of additively forming a core portion as an inner portion of an additive manufactured object by stacking first weld beads each size of which is corresponding to a first resolution; and a shell portion forming step of additively forming a shell portion as an outer portion of the additive manufactured object on a surface of the core portion by stacking second weld beads each size of which is corresponding to a second resolution higher than the first resolution after the core portion forming step.

Dependent claims

A production method for additive manufactured object, the method comprising:

a core portion forming step of additively forming a core portion as an inner portion of an additive manufactured object by stacking first weld beads each size of which is corresponding to a first resolution;
and
a shell portion forming step of additively forming a shell portion as an outer portion of the additive manufactured object on a surface of the core portion by stacking second weld beads each size of which is corresponding to a second resolution higher than the first resolution after the core portion forming step.

A production system for additive manufactured object, the system comprising:

a welding head;
and
an additive forming control device which is configured to control the welding head so that an additive manufactured object is formed by operating the welding head,
wherein the additive forming control device includes:
a core portion forming control unit which is configured to control the welding head so that a core portion as an inner portion of the additive manufactured object is additively formed by stacking first weld beads each size of which is corresponding to a first resolution;
and
a shell portion forming control unit which is configured to control the welding head so that a shell portion as an outer portion of the additive manufactured object is additively formed on a surface of the core portion by stacking second weld beads each size of which is corresponding to a second resolution higher than the first resolution after at least part of the core portion is additively formed.
