A method of manufacturing a three-dimensional target object may include forming a shell from loose machining powder using an additive manufacturing process and subjecting the shell to a densification process to form a target object. The shell may define an enclosure that contains additional machining powder. The densification process may include causing metallurgical bonding between the shell and additional machining powder contained in the enclosure defined by the shell and shrinking and/or distorting the shape of the shell to conform the target object to a three-dimensional model for the target object. The shell may include a plurality of layers and/or parts that differ at least in respect of density. The plurality of layers and/or parts may be configured based at least in part on the shrinking and/or distorting to the shape of the shell needed to conform the target object to the three-dimensional model for the target object.

Embodiments disclosed herein involve polycrystalline diamond (“PCD”) tables and polycrystalline diamond compacts (“PDCs”) that include PCD tables as well as methods and apparatuses for manufacturing thereof. Some embodiments include a canister assembly that may be used in a high-pressure/high-temperature (“HPHT”) process or other heating process to manufacture the PCD tables and/or the PDCs.

A preparation process of a novel drill shank for an IMPACT gun drill, including: manufacturing a mold and a forming block, wherein a forming blind hole is formed in a middle of the mold, the forming block is inserted into the forming blind hole, a wire pipe is disposed in the mold, a feed port is formed in the forming block, a heating cavity is formed in a forming block lateral face and a forming post; manufacturing the forming block with a 2Cr25Ni20 material; injecting tin bronze powder and iron powder into the forming blind hole, starting vibration pressing by the forming block; inputting direct and pulse current to communicate with the metal powder and heat the metal powder at a same time; forming a drill shank blank after 2-3 min, taking out the drill shank blank; removing an adsorbing agent from the drill shank blank by an extraction method.

A method for manufacturing a metallic component including the steps of providing a capsule, which defines at least a portion of the shape of the metallic component, arranging metallic material in the capsule, sealing the capsule, subjecting the capsule to Hot Isostatic Pressing for a predetermined time, at a predetermined pressure and at a predetermined temperature, and optionally, removing the capsule. The metallic material is at least one pre-manufactured coherent body, which pre-manufactured coherent body being made of metallic powder, wherein at least a portion of the metallic powder is consolidated such that the metallic powder is held together into a pre-manufactured coherent body. At least one portion of the pre-manufactured coherent body is manufactured by Additive Manufacturing by subsequently arranging superimposed layers of metallic powder.

A method of fabricating a component is described and involves retaining a canister as an integral part of the component after performing an isostatic pressing process. The method comprises: providing a canister having a canister wall that encloses an internal cavity, the canister wall comprising at least a first wall section and a second wall section, where the first wall section and the second wall section are of different materials; filling the internal cavity with a powdered material; performing an isostatic pressing process on the filled canister to consolidate the powder; and retaining the canister as an integral part of the component such that an internal structure of the component comprises the consolidated powder and the canister wall forms at least part of a surface of the component that covers the internal structure.

A containment for use in hot Isostatic pressing, the containment comprising a body formed from sheet material and fused together along its longitudinal length using a backing strip on the outside of body. Also a containment with a body and top and bottom caps diffusion bonded upon hot isostatic pressing, a containment with a gas purge inlet and outlet and an apparatus for vacuum degassing are disclosed.

An additive manufacturing system includes a build platform, a plurality of particles positioned on the build platform defining a build layer, a first and second region within the build layer, and at least one consolidation device. The first region and the second region each including a portion of the plurality of particles. The at least one consolidation device is configured to consolidate the plurality of particles within the build layer into a solid, consolidated portion of said build layer. The consolidation device is further configured to consolidate at least one of the plurality of particles within the build layer and the solid, consolidated portion of the build layer into a molten volume of transfer material. The consolidation device is further configured to transfer a portion of the molten volume of transfer material within the first region from the first region to the second region.

An isostatic pressing canister for use in manufacturing a component by isostatic pressing is described. The canister comprises: a canister wall enclosing an internal cavity, the canister wall having an internal surface facing the internal cavity; a filling point for filling the internal cavity with powdered material, the filling point comprising a hole in the canister; and a structure supported within the internal cavity and located between the hole and the portion of the internal surface opposite the hole. A portion of the internal surface of the canister wall opposite the hole is shaped so that, during the filling of the internal cavity, powdered material falling from the hole and towards the portion of the internal surface is deflected away from the portion of the internal surface. A method of manufacturing a component using the canister is also described.
