Abstract
In an example of a method for three-dimensional (3D) printing, a polymeric or polymeric composite build material is applied. A dielectric agent is selectively applied on at least a portion of the polymeric or polymeric composite build material. The dielectric agent includes a dielectric material having an effective relative permittivity (εr) value ranging from 1.1 to about 10,000. A fusing agent is selectively applied on the at least the portion of the polymeric or polymeric composite build material, and the polymeric or polymeric composite build material is exposed to radiation to fuse the at least the portion of the polymeric or polymeric composite build material to form a region of a layer of a 3D part. The region exhibits a dielectric property, a piezoelectric property, or a combination thereof.
