摘要： A rotary-type earth-boring drill bit including a layer-manufactured, substantially hollow bit crown and an integral bit interior and bit gage. The bit interior and bit gage may be formed of a particulate material infiltrated with an infiltrant material. A particulate material of the bit crown may be integrally infiltrated with the particulate material of the bit interior and bit gage. Alternatively, the bit interior and bit gage may comprise a single cast material. The particulate material of the bit crown may be infiltrated with the cast material of the bit interior and bit gage. A method of fabricating the drill bit includes employing known layered-manufacturing techniques to fabricate the bit crown, positioning a bit gage mold adjacent the bit crown, and disposing a core material within an interior of the bit crown and a cavity of the bit gage mold. A mold that may be employed to fabricate the drill bit includes an initially conforming mold region, in which the pre-fabricated bit crown may be disposed, and a second, substantially rigid mold region including a cavity to define the gage of the drill bit. Preferably, the conforming mold region is formed of a non-wettable, granular material.

摘要： A method of fabricating rotary-type drill bits, drilling-related structures, and other articles of manufacture. The method includes fabricating a machinable matrix, machining the matrix, and dispersing a binder material throughout the matrix. The matrix of the rotary-type drill bit may be fabricated by layered-manufacturing techniques or by disposing a particulate or powdered material into a mold and binding the particles together with a resin or by sintering. The matrix may have the desired dimensions and features, the approximate dimensions and features, or lack desired dimensions or features of a drilling-related structure or other article of manufacture. The matrix is machined to correct any anisotropies or imperfections of the matrix, to refine features of the matrix, or to define the features in the matrix. The machined matrix may be infiltrated with a binder material to define a drill bit body.

摘要： A method of manufacturing a drill bit or other drilling-related structure used for drilling into subterranean formations is herein disclosed where a blank is formed by placing a ferrous metal powder such as steel into a mold, sintering the ferrous metal powder to form a preformed blank, packing an abrasion- and erosion-resistant material such as tungsten carbide powder around the preformed blank, and infiltrating the preformed blank and tungsten carbide with a common binder such as a copper-based binder. For some materials, during sintering, the preformed blank may shrink in size relative to the mold enough to provide space between the mold and the preformed blank for a layer of abrasion- and erosion-resistant material. With other materials, a separate blank mold may be used to form the sintered blank which can then be inserted into the mold for infiltration. Accordingly, the same or substantially similarly configured mold can be used to form the preformed blank and the finished drill bit or drilling-related structure having a sintered steel core and a tungsten carbide shell infiltrated with a copper-based binder.
