Abstract: The present disclosure provides methods of three-dimensional printing, including iteratively applying individual build material layers of polyamide particles and selectively applying a fusing agent onto the individual build material layers to form individually patterned object layers. The fusing agent can include water and a radiation absorber. The method can also include selectively applying a pore-promoting agent onto the individual build material layers at some or all of the individually pattered object layers to form a pore-generating region, and iteratively exposing the individual build material layers to electromagnetic energy to generate molten polymer from polyamide particles in contact with the radiation absorber that upon cooling forms fused polymer body. A material used to form the fused polymer body without pores can exhibit a material dielectric permittivity, and the fused polymer body at a location that includes the pores can exhibit a decreased dielectric permittivity.
