Abstract: A method includes providing a collection of particulate material and forming a first article therefrom. Forming the first article includes forming an outer shell with an outer surface that defines an outer periphery of the first article; forming a relief area of the first article that supports the outer shell, including forming a relief void in the relief area; and collecting a collection of the particulate material within the outer shell during formation of the first article. Moreover, the method includes encasing the first article with an outer member. The outer member defines an internal cavity with an internal surface that corresponds to the outer surface of the outer shell. The method further includes heating, which deforms the first article selectively at the relief void.

Abstract: A method of manufacturing a directionally solidified article of the present disclosure includes providing a collection of particulate material and additively manufacturing a first article with an outer wall from the particulate material. The outer wall defines at least part of a cavity. The cavity contains an amount of the particulate material. The method also includes encasing at least a portion of the first article with an outer member. The outer member defines an internal cavity that corresponds to the first article. The method further includes heating the outer member and the first article to melt the first article into a molten mass within the internal cavity of the outer member. Additionally, the method includes solidifying the molten mass along a predetermined solidification path within the outer member to form a second article that corresponds to at least a portion of the internal cavity of the outer member.
