Abstract

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.
