ABSTRACT:
A method for making an engine component with a hollow interior includes the steps of: selectively patterning a principal substrate surface; forming a slurry including a selected amount of a binder material, a selected amount of a solvent and a selected amount of a filter material; inserting the slurry into the substrate surface pattern; evaporating the solvent to solidify the slurry; depositing a close-out layer of material over the patterned substrate surface and over the solidifed slurry; and without removing the close-out layer, removing the solidified slurry to provide a structure with a hollow interior.
