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.
