ABSTRACT:
Disclosed herein is an integral casting core including a solidified first portion of a ceramic core and a solidified second portion of the ceramic core; wherein the solidified second portion is disposed upon the solidified first portion of the ceramic core by laser consolidation. The first solidified portion of the integral casting core, is manufactured by a process which includes disposing a slurry including ceramic particles into a metal core die; wherein an internal volume of the metal core die has a geometry equivalent to a portion of the geometry of the integral casting core; curing the slurry to form a cured first portion of the ceramic core; and firing the cured first portion of the ceramic core to form a solidified first portion of the ceramic core.
