The present disclosure describes multi-fluid kits for printing three-dimensional green body objects, three-dimensional printing kits, and methods of three-dimensional printing. In one example, a multi-fluid kit for printing a three-dimensional green body object can include an adhesion promoter agent and a binder agent. The adhesion promoter agent can include water and a dihydrazide compound. The binder agent can include water, an organic co-solvent, a glycidyl compound having two or more glycidyl groups per molecule, and latex particles. The latex particles can include polymerized monomers. The polymerized monomers can include a first monomer having an acid group and a second monomer having a vinyl group and without an acid group.

The disclosure describes example techniques and assemblies for joining a first component and a second component. The techniques may include positioning the first and second component adjacent to each other to define a joint region between adjacent portions of the first component and the second component. The techniques may also include inserting a solid retainer material into the joint region through an aperture in one of the first component or the second component to form a mechanical interlock between the first component and the second component and sealing the aperture to retain the solid retainer material within the joint region. The solid retainer material includes at least one of a metal, a metal alloy, or a ceramic.

Methods, systems, and devices for precision locating additively manufactured components for assembly and/or post processing manufacturing are provided for herein. In some embodiments, at least one component can be additively manufactured to include one or more kinematic features on one or more surfaces of the component. The kinematic feature(s) can be configured to engage complementary kinematic feature(s) formed in a second component so the two components can form an assembly. Alternatively, the kinematic feature(s) can be configured to engage complementary kinematic feature(s) associated with a post-processing machine such that the one or more post-processing actions can be performed on the component after the component is precisely located with respect to the machine by way of the kinematic features of the component and associated with the machine. A variety of systems and methods that utilize kinematic features are also provided.

A method for producing a machining segment for a machining tool, where the machining segment is connectable to a basic body of the machining tool by an underside of the machining segment, includes producing a green body by placing first hard material particles in a matrix material in a defined particle pattern, where the first hard material particles are placed in the matrix material with a respective projection with respect to the matrix material. The green body is compacted by pressure between a first press punch, which forms the underside, and a second press punch, which forms an upper side of the machining segment, to form a compact body, where the upper side is opposite from the underside. The compact body is processed by temperature or by infiltration to produce the machining segment.
