    Abstract: A method of making a pre-sintered preform, including forming a pre-sintered preform by a binder jet additive manufacturing technique. The binder jet additive manufacturing technique includes depositing a first powder layer including a first powder and a second powder followed by depositing a first binder at a pre-determined location of the first powder layer. The binder jet additive manufacturing technique also includes depositing a second powder layer over at least a portion of the first powder layer followed by depositing a second binder at a pre-determined location of the second powder layer. At least a portion of the first binder and at least a portion of the second binder is cured forming a green part. The green part is then densified to form a pre-sintered preform near net shape component.

    Abstract: An article and a method for making shaped cooling holes in an article are provided. The method includes the steps of depositing a metal alloy powder to form an initial layer including at least one aperture, melting the metal alloy powder with a focused energy source to transform the powder layer to a sheet of metal alloy, sequentially depositing an additional layer of the metal alloy powder to form a layer including at least one aperture corresponding to the at least one aperture in the initial layer, melting the additional layer of the metal alloy powder with the focused energy source to increase the sheet thickness, and repeating the steps of sequentially depositing and melting the additional layers of metal alloy powder until a structure including at least one aperture having a predetermined profile is obtained. The structure is attached to a substrate to make the article.

    Abstract: A component and method of forming a component are disclosed. The component includes a cast alloy section and an additive manufacturing section secured to the cast alloy section. Both the cast alloy section and the additive manufacturing section form at least a portion of an outer surface of the component. The method of forming a component includes removing a portion of an existing component, the removing of the portion forming an open section in the existing component, forming an article through an additive manufacturing technique, the article having a shape and geometry arranged and disposed to fill the open section in the existing component, and securing the article within the open section of the existing component to form the component. Another method includes directly depositing a material, by an additive manufacturing technique, over a portion of the existing component.

    Abstract: A cooling article and method of forming a cooling article are provided. The cooling article includes a body portion separating an inner region and an outer region, an aperture in the body portion, the aperture fluidly connecting the inner region and the outer region, and a reinforcing feature extending at least partially along the body portion, the reinforcing feature being oriented with respect to a build direction. The method includes forming a body portion defining an inner region and an outer region, forming at least one reinforcing feature concurrently with the forming of the body portion, the at least one reinforcing feature extending at least partially along the body portion, and forming an aperture in the body portion, the aperture fluidly connecting the inner region to the outer region. The forming the body portion, forming the aperture, and forming the at least one reinforcing feature comprises additive manufacturing.
