METHOD AND ASSEMBLY FOR FORMING COMPONENTS HAVING INTERNAL PASSAGES USING A LATTICE STRUCTURE

A mold assembly (301) for use in forming a component (80) having an internal passage (82) defined therein is provided. The component is formed from a component material (78). The mold assembly includes a mold (300) that defines a mold cavity (304) therein. The mold assembly also includes a lattice s...

Beschreibung
Zusammenfassung:	A mold assembly (301) for use in forming a component (80) having an internal passage (82) defined therein is provided. The component is formed from a component material (78). The mold assembly includes a mold (300) that defines a mold cavity (304) therein. The mold assembly also includes a lattice structure (340) selectively positioned at least partially within the mold cavity. The lattice structure is formed from a first material (322) that has a selectively altered composition in at least one region (380) of the lattice structure. A channel (344) is defined through the lattice structure, and a core (324) is positioned in the channel such that at least a portion (315) of the core extends within the mold cavity and defines the internal passage when the component is formed in the mold assembly.
