Abstract

In an example of a method for three-dimensional printing, a first amount of a binding agent is selectively applied, based on a 3D object model, to individual build material layers of a particulate build material including metal particles to forming an intermediate structure. The binding agent and/or a void-formation agent is selectively applied, based on the 3D object model, to at least one interior layer of the individual build material layers so that a total amount of the binding agent, the void-formation agent, or both the binding agent and the void-formation agent in the at least one of the individual build material layers is greater than the first amount. This patterns an area that is to contain voids. The intermediate structure is heated to form a 3D structure including a void-containing breakable connection.
