Abstract

A method of infiltrating preformed, bonded-particulate components, such as rotary bits, for subterranean drilling manufactured by techniques such as layered-manufacturing or those employed in rapid prototyping technology. A support structure is provided for the preformed component to physically support the preformed component during various manufacturing processes such as sintering and infiltration.
