A mold assembly for use in forming a component having an internal passage defined therein is provided. The component is formed from a component material. The mold assembly includes a mold that defines a mold cavity therein. The mold assembly also includes a lattice structure selectively positioned at least partially within the mold cavity. The lattice structure is formed from a first material that has a selectively altered composition in at least one region of the lattice structure. A channel is defined through the lattice structure, and a core is positioned in the channel such that at least a portion of the core extends within the mold cavity and defines the internal passage when the component is formed in the mold assembly.

The method of claim 12, wherein the mold is formed from a mold material, the component material is an alloy that includes at least one constituent reactive with the mold material, and the first material includes the at least one reactive constituent, said selectively positioning the lattice structure comprises selectively positioning the lattice structure that includes a second region of the at least one region formed from the first material selectively altered to include a reduced content of the at least one reactive constituent. 18. The method of claim 17, wherein said selectively positioning the lattice structure comprises selectively positioning the lattice structure that includes the second region defined proximate a perimeter of the lattice structure. 19. The method of claim 12, wherein said selectively positioning the lattice structure comprises selectively positioning the lattice structure configured to at least partially support a weight of the core during at least one of pattern forming, shelling of the mold, and/or component forming. 20. The method of claim 12, wherein said selectively positioning the lattice structure comprises selectively positioning the lattice structure that includes the channel defined by a hollow structure that encloses the core. 21. The method of claim 20, wherein said selectively positioning the lattice structure comprises selectively positioning the lattice structure that includes the hollow structure integral to the lattice structure. 22. The method of claim 21, wherein said selectively positioning the lattice structure comprises selectively positioning the lattice structure that defines a perimeter shaped for insertion into the mold cavity through an open end of the mold, such that the lattice structure and the hollow structure define an insertable cartridge.
