Claim Text:
1. A method for fabricating a carbide composite for a downhole tool, comprising: depositing a first layer on a substrate, the first layer comprising one or more first carbides, the first layer being from about 0.0005 cm to about 0.06 cm thick; depositing a second layer at least partially adjacent the first layer, the second layer comprising one or more second carbides, metal binders, organic binders, or a combination thereof, the second layer being from about 0.0005 cm to about 0.06 cm thick, and wherein the first and second layers have a different particle size, particle shape, carbide concentration, metal binder concentration, or organic binder concentration from one another; and binding the first and second layers to form the carbide composite, wherein the first and second layers are formed by additive manufacturing using a CAD assembly.
