Methods of making metal bond abrasive articles via powder bed jetting are disclosed. Metal bond abrasive articles prepared by the method include abrasive articles having arcuate or tortuous cooling channels, abrasive segments, abrasive wheels, and rotary dental tools.

Multi-material tooling and methods of making multi-material tooling are provided. The multi-material tooling includes a core formed of a first material having a hardness (Rockwell C scale) of up to 30 HRC, and a shell layer adjacent to the core. The shell layer is formed of a second material having a hardness of 33 HRC to 70 HRC. The method of making multi-material includes depositing a first layer of a first material using an additive manufacturing technique to form a core. The first material that forms the core has a hardness of up to 30 HRC. The method also includes depositing a second layer of a second material to form a shell layer adjacent to the core. The second material that forms the shell layer has a hardness of 33 HRC to 70 HRC.

A method for manufacturing a high-torque hexagonal drill shank includes: firstly producing an air module, wherein the lower end of the air module is inserted into a molding cavity of a mold, a high-pressure air is injected into the air module, and the surface of the air module is provided with a plurality of air outlets; evenly mixing metal powder and an organic binder together; injecting obtained particulates in a heating-plasticizing state into the molding cavity by an injection molding machine to solidify and form a hexagonal drill shank blank; forming a non-cylindrical cavity inside the hexagonal drill shank blank under the action of the air module; removing the binder in the hexagonal drill shank blank by thermal decomposition; and, finally, obtaining a high-torque hexagonal drill shank by sintering and densifying.

A high-speed machining tool made of a steel-bonded carbide and a method for preparing the same relate to the technical field of lathe tools made of steel-bonded carbides, and overcome the problems of traditional steel-bonded carbide lathe tools about low hardness and low toughness. The high-speed machining tool includes a skeleton, a main body, and a coating. The main body is consolidated by the skeleton from inside. The skeleton and the main body are both ringlike in shape. The main body has its outer surface covered by the coating. The high-speed machining tool is such made that the skeleton is hard and the main body is tough. The blade of the tool is hard and can transfer vibrations to the main body, thereby protecting the tool from brittle fractures and improving the overall performance of the tool.

A composite article includes a lattice and an elastomeric section. The lattice includes a plurality of members that form an open-mesh frame defining a plurality of voids between the adjacent members of the frame. The elastomeric section is formed of an elastomer that is disposed about the lattice and within the voids of the lattice. The composite article may be a circular gasket, a gasket with a grip, a rectangular gasket, a vessel cap, a flask stand, and a handle for a hand tool.
