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.
