Abstract
A method of manufacturing an earth-boring bit having a fluid plenum and a plurality of fluid pathways includes modeling flow characteristics of the fluid plenum and the plurality of fluid pathways, optimizing the flow characteristics to minimize fluid separation through each fluid pathway, constructing a plenum blank from the optimized model, and sintering matrix power between the plenum blank and a bit head mold to create the fluid plenum and plurality of fluid pathways.
