Abstract: A method of designing and forming at least one element of an acoustic transducer. The method includes receiving one or more required operating parameters of the at least one element of the acoustic transducer for an application, iteratively modeling and simulating performance of one or more materials to utilize within the at least one element of the acoustic transducer, iteratively modeling and simulating performance of one or more structures to utilize within the at least one element of the acoustic transducer, identifying at least one material and at least one structure that exhibit predicted performance that at least achieves the one or more required operating parameters of the at least one element of the acoustic transducer for the application, outputting a design of the at least one element of the acoustic transducer, and forming the at least one element of the acoustic transducer via one or more additive manufacturing processes.

Abstract: A method of manufacturing an earth boring tool body including the following steps: providing a mold, the mold comprising a mold cavity defining an interior surface corresponding to an exterior shape of a tool body and a plurality of blades. Forming at least one barrier sleeve insert and disposing it adjacent the interior surface defining the mold cavity; disposing a first powder in the gap between the insert and the interior surface, disposing a second powder in the mold cavity; disposing an infiltrant material adjacent the powders; and heating the mold, thereby infiltrating the infiltrant material into the powders to form the tool body. The disclosure also includes a mold for manufacturing an earth boring tool, the mold comprising a mold cavity defining interior surfaces corresponding to an exterior shape of the tool body and the plurality of blades. Barrier sleeve inserts and/or containment sleeve inserts may be disposed adjacent interior surfaces the mold cavity.
