Abstract
A three-dimensional printing kit includes a build material composition and a dielectric agent. The build material composition includes a fluorinated polymeric material having an effective relative permittivity (εr) value ranging from >3 to ≤10,000. The dielectric agent includes a dielectric material having an effective relative permittivity (εr) value ranging from ≥1.1 to about ≤10,000.

The method as defined in claim 9 wherein the fusing agent includes an energy absorber and a liquid vehicle, and wherein the energy absorber is a plasmonic resonance absorber having absorption at wavelengths ranging from 800 nm to 4000 nm and having transparency at wavelengths ranging from 400 nm to 780 nm.
A method for three-dimensional printing, comprising:
- applying a layer of a build material composition including a fluorinated polymeric material having an effective relative permittivity (εr) value ranging from >3 to ≤10,000;
- based on a 3D object model, selectively applying a fusing agent on the layer to form a patterned portion;
- based on the 3D object model, patterning an energy storage portion of a 3D object by selectively depositing a dielectric agent on at least a portion of the patterned portion to deliver a predetermined concentration of a dielectric material to the energy storage portion, the dielectric material having an effective relative permittivity (εr) value ranging from 1.1 to about 10,000;
- and
- exposing the layer to energy to coalesce the patterned portion to form a 3D object layer including the energy storage portion.
