Additive manufactured fired body, and method for manufacturing the additive manufactured fired body

A method for manufacturing an additive manufactured fired body, the method comprising:

• a manufacturing step of manufacturing an additive manufactured object by using an additive manufacturing powder;
• and
• a firing step of obtaining the additive manufactured fired body by firing the additive manufactured object,
• wherein the manufacturing step includes manufacturing, together with manufacturing the additive manufactured object, a supporter surrounding and supporting the additive manufactured object,
• wherein manufacturing the supporter includes manufacturing, by using the additive manufacturing powder, a frame of the supporter such that the frame has openings therein,
• wherein manufacturing the supporter includes manufacturing, by using the additive manufacturing powder, a holding portion of the supporter disposed inside the frame such that the holding portion has a mesh shape and spans at least one of the openings of the frame,
• wherein the holding portion comprises a first holding portion and a second holding portion,
• wherein the first holding portion extends from an upper surface on one end portion of two ends of the supporter and a lower surface on another end portion of the two ends of the supporter toward the additive manufactured object,
• wherein tips of the first holding portion do not come into contact with the additive manufactured object,
• wherein the second holding portion extends from the upper surface and the lower surface of the supporter toward an opposing surface and connects the upper surface and the lower surface,
• wherein the second holding portion and the additive manufactured object do not come into contact with each other,
• wherein the additive manufactured object and the supporter have same constituent materials,
• wherein the frame of the supporter is open on two ends in one direction,
• wherein the holding portion spans the openings of the frame, and
• wherein the additive manufactured object is movable inside the supporter.
