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.

Abstract: The present disclosure relates a method of 3-dimensional printing a printed part. The method comprises printing an inkjet dopant composition at selected locations on a layer of build material comprising polymer particles. The inkjet dopant composition comprises a dopant dispersed or dissolved in a liquid carrier. Polymer particles at selected areas of the layer of build material are then fused to form a fused polymer layer comprising the dopant. The selected areas of the layer of build material include areas of the layer of build material that have not been printed with the inkjet dopant composition.

Abstract: The present disclosure relates to a build composition for a 3-dimensional printing process. The build composition comprises thermoplastic polymer particles, a first photoluminescent agent and a second photoluminescent agent. The build composition has a spectral signature characteristic of the presence of the first photoluminescent agent and the second photoluminescent agent in combination.
