Abstract: A structure and method are provided for forming a box for molding an article for use in casting. A wall defines a cavity formed in a shape of the article and configured to receive a material for forming the article. A rim is disposed around the wall and extends therefrom defining a hollow back on an opposite side of the wall from the cavity. A lattice structure formed in the hollow back and is connected with the wall and with the rim. The box may be formed by additive manufacturing.

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.
