Abstract: In an example of a three-dimensional (3D) printing method for forming a pharmaceutical tablet, build material granules are applied. Each of the build material granules includes a plurality of excipient particles, wherein at least one of the plurality of excipient particles is a latent binder. Pressure is applied to the build material granules. An activation solvent is selectively applied on at least a portion of the pressed build material granules. An active pharmaceutical ingredient formulation including an active pharmaceutical ingredient is selectively applied on the at least the portion of the pressed build material granules. The activation solvent is evaporated.

Abstract: A metallic build material granule includes a plurality of primary metal particles and a temporary binder agglomerating the plurality of primary metal particles together. The primary metal particles have a primary metal particle size ranging from about the 1 μm to about 20 μm. The primary metal particles are non-shape memory metal particles, and the metallic build material granule excludes shape memory metal particles.

Abstract: In a three-dimensional printing method example, build material granules are applied. Each of the build material granules includes uncoated, primary ceramic particles agglomerated together by a binder that is soluble in a primary solvent of a fusing agent. The fusing agent is selectively applied on at least a portion of the build material granules. The binder dissolves and a green body including a slurry of the uncoated, ceramic particles is created.

Abstract: In a three-dimensional (3D) printing method example, build material granules are applied. Each of the build material granules includes a plurality of primary ceramic particles agglomerated together by a binder that is at least partially soluble in a primary solvent of a fusing agent. Pressure is applied to crush the build material granules. The fusing agent is selectively applied on at least a portion of the build material granules or the crushed build material granules to pattern the portion, and to introduce a latent binder to the portion. The application of the build material granules, the application of the pressure, and the selectively application of the fusing agent are repeated to create a green body. The latent binder is activated by heating the green body in order to produce a cured green body.

Abstract: In a three-dimensional printing method example, a build material, including an epoxy resin powder, is applied. A hardener liquid is selectively applied on at least a portion of the build material. The portion of the build material in contact with the hardener liquid is allowed to cure to form a layer of a 3D part. In another three-dimensional printing method example, a filler build material is applied. A liquid epoxy resin is selectively applied on at least a portion of the filler. A hardener liquid is selectively applied on the at least the portion of the filler. The portion of the filler in contact with the liquid epoxy resin and the hardener liquid is allowed to cure to form a layer of a 3D part.

Abstract: In an example implementation, a method of producing a three-dimensional (3D) object includes patterning an unfused 3D object within a work area of a printing platform and stabilizing the unfused 3D object for removal from the work area.

Abstract: The present disclosure is drawn to ink sets, material sets, and 3-dimensional printing systems. An ink set can include a pretreat composition that includes a metal chloride salt, a conductive fusing ink including a transition metal, and a second fusing ink. The second fusing ink can include a fusing agent capable of absorbing electromagnetic radiation to produce heat.
