In an example of a method for three-dimensional (3D) printing, build material layers are patterned to form an intermediate structure. During patterning, a binding agent is selectively applied to define a patterned intermediate part. Also during patterning, i) the binding agent and a separate agent including a gas precursor are, or ii) a combined agent including a binder and the gas precursor is, selectively applied to define a build material support structure adjacent to at least a portion of the patterned intermediate part. The intermediate structure is heated to a temperature that activates the gas precursor to create gas pockets in the build material support structure.

A method for manufacturing an electromagnetic shielding film of reduced thickness and a simplified manufacturing process includes forming a conductive ink layer by inkjet printing, on a component to be shielded, forming an insulative ink layer on the conductive ink layer by inkjet printing, and sintering the conductive ink layer and the insulative ink layer to form an electromagnetic shielding layer and an insulative layer, thereby obtaining the electromagnetic shielding film.
