  • Publication number: 20240001442
    Abstract: A method for manufacturing a three-dimensional object includes: a modeling step of modeling an intermediate object by applying a binding fluid to a metal powder containing titanium; and a sintering step of sintering the intermediate object to produce a three-dimensional object. The modeling step is performed in a vacuum or inert gas atmosphere. When the modeling step is performed in a modeling area and the method includes a curing step of curing the binding fluid included in the intermediate object in a curing area different from the modeling area after the modeling step and before the sintering step, the curing step is performed in a vacuum or inert gas atmosphere. A moving path for moving the intermediate object having gone through the modeling step from the modeling area to the curing area is in a vacuum or inert gas atmosphere.
