Abstract: The present disclosure is drawn to multi-fluid kits for three-dimensional printing, three-dimensional printing kits, and methods of making three-dimensional printed articles. In one example, a multi-fluid kit for three-dimensional printing can include a fusing agent, a first reactive agent, and a second reactive agent. The fusing agent can include water and a radiation absorber. The first reactive agent can include a first liquid vehicle and an epoxy compound having multiple epoxide groups. The second reactive agent can include a second liquid vehicle and an amine compound having multiple amino groups.

Abstract: The present disclosure relates to a method of three-dimensional (3D) printing a 3D printed object. The method comprises: selectively jetting a marking agent onto a first region of build material, wherein the build material comprises at least one meta and/or ceramic; selectively jetting a binding agent onto at least a portion of the build material; and binding the build material to form a layer; such that the marking agent is incorporated in the metal part in a predetermined arrangement that forms a detectable marker in the 3D printed object. The disclosure also relates to a multi-fluid inkjet kit for 3D printing.

Abstract: Apparatus and methods for making metal-connected particle articles. A metal containing fluid is selectively applied to a layer of particles. The metal in the fluid is used to form metal connections between particles. The metal connections are formed at temperatures below the sintering temperature of the particles in the layer of particles.

Abstract: In an example method for forming three-dimensional (3D) printed electronic parts, a build material is applied. An electronic agent is selectively applied in a plurality of passes on a portion of the build material. A fusing agent is also selectively applied on the portion of the build material. The build material is exposed to radiation in a plurality of heating events. During at least one of the plurality of heating events, the portion of the build material in contact with the fusing agent fuses to form a region of a layer. The region of the layer exhibits an electronic property. An order of the plurality of passes, the selective application of the fusing agent, and the plurality of heating events is controlled to control a mechanical property of the layer and the electronic property of the region.

Abstract: In one example in accordance with the present disclosure, a system is described. The system includes a reader to 1) read an identifier from a three-dimensional (3D) System printed object that includes a storage element and 2) read a location of the 3D printed object within a build material bed. An extractor of the system extracts, based on the identifier, a post processing operation to execute on the 3D printed object. A controller of the system controls a post processing operation based on extracted post processing operation information and the location.

Abstract: A shaping composition for controlling deformation of a green body object during heat fusing can include a liquid vehicle present at from 10 wt % to about 80 wt %, based on a total weight of the shape retaining composition, and a metal particulate mixture present at from about 20 wt % to about 90 wt % based on a total weight of the shaping composition. The metal particulate mixture can include aluminum-containing particulates and secondary metal-containing particulates. The metal particulate mixture can have an aluminum elemental content to secondary metal elemental content atomic ratio of about 10:1 to about 1:2.
