    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.

    Abstract: In an example, a method includes, by one or more processors, receiving a greyscale image having a plurality of pixels, each pixel being associated with a grey level, and the greyscale image having a first number of grey levels. An order of the pixels may be determined based on the grey level. A second number of grey levels may be determined, wherein the second number of grey levels is greater than the first number, and an indication of a target number of pixels per grey level of the second number of grey levels may be further be determined. Taking the pixels in order, and based on the target number of pixels per grey level, a new grey level may be allocated to each pixel to provide the second number of grey levels. The new grey levels may be converted to a threshold of a threshold halftone screen.
