In an example of a method for three-dimensional (3D) printing, metallic build material layers are patterned to form an intermediate structure. During patterning, a binding agent is selectively applied to define: a build material support structure and a patterned intermediate part. Also during patterning, i) the binding agent and a separate agent including an etch sensitizer or ii) a combined agent including a binder and the etch sensitizer are selectively applied to define a patterned etchable connection between at least a portion of the build material support structure and at least a portion patterned intermediate part. The intermediate structure is heated. |
