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.

A method of 3-dimensional printing a printed part, the method comprising:
- applying a particulate polymeric or polymeric composite build material;
- printing an inkjet dopant composition including a dopant comprising dielectric particles at selected locations on a layer of the polymeric or polymeric composite build material;
- printing an inkjet fusing composition onto selected areas of the layer of build material, wherein the fusing composition includes a fusing agent to absorb electromagnetic radiation to produce heat;
- and
- exposing at least a portion of the layer of build material to electromagnetic radiation, thereby heating the selected areas of the layer of build material having the inkjet fusing composition printed thereon, and fusing polymer particles at the selected areas of the layer of build material to form a fused polymer layer comprising dielectric particles;
- wherein the fused polymer layer comprising dielectric particles exhibits a dielectric property.
