description At least one feed core (62) and at least one wall cooling core (64A) are assembled with a number of elements (202, 204) of a die (200) for forming a cooled turbine engine element investment casting pattern. A sacrificial material (222) is molded in the die (200). The sacrificial material (222) is removed from the die (200). The removing includes extracting a first of the die elements (210A) from a compartment (230A) in a second (202) of the die elements before disengaging the second die element (202) from the sacrificial material (222). The first element (210A) includes a compartment (134, 136) receiving an outlet end portion (94) of a first of the wall cooling cores (64A) in the assembly and disengages therefrom in the extraction.
