Abstract
An example mold assembly for fabricating an infiltrated downhole tool includes a mold forming a bottom of the mold assembly, and a funnel operatively coupled to the mold and having an inner wall, an outer wall, and a cavity defined between the inner and outer walls. An infiltration chamber is defined at least partially by the mold and the funnel. The inner wall faces the infiltration chamber and the outer wall forms at least a portion of an outer periphery of the mold assembly.
