A method of forming an earth-boring tool includes forming a tool body including at least one inverted cutting element pocket, at least a portion of the at least one inverted cutting element pocket having a profile substantially matching a profile of an actual cutting element to be secured within a cutting element pocket to be formed by subsequently machining the at least one inverted cutting element pocket. Hardfacing material may be applied to portions of the tool body. The actual cutting element pocket is formed by removing material of the tool body within the at least one inverted cutting element pocket subsequent to applying the hardfacing material to portions of the tool body. A cutting element is affixed within the actual cutting element pocket.

A system for producing an object is disclosed including a build device having a build area and a material bonding component to receive portions of a material that are used to produce the object, at least one gripper within the build area to contact the object to provide support and to provide for at least one of a heat sink for the object, a cold sink for the object, and electrical dissipation path from the object, and a movement mechanism to move the build device relative to the object to position the build device at a position to further produce the object. Another system and methods are also disclosed.

In a method for the production of a seamless, multilayered tubular product, a further layer is applied through hardfacing on a base layer of a round or polygonal block, with the further layer made of a metallic material which is different than a metallic material of the base layer. The round or polygonal block with hardfaced further layer is hot formed to produce a tubular product with reduced wall thickness and outer perimeter in one or more stages. A diffusion layer is established between the base layer and the further layer through heat treatment before hot forming and/or after hot forming, thereby producing a thickness of the diffusion layer of at least 5 m with the proviso that the thickness of the diffusion layer is 0.1% to 50% of a thickness of the further layer, with the thickness of the further layer being equal to or greater than 100 m.
