Abstract
In an example, an apparatus for generating a three-dimensional object includes a build area platform, a build material distributor, a secondary material ejection device, a coalescing agent ejection device, and a controller. The controller may control the secondary material ejection device to eject a secondary material in a predefined pattern over the build area platform, control the build material distributor to distribute a layer of the build material around the ejected secondary material, control the coalescing agent ejection device to eject the coalescing agent onto the layer of the build material, and control an energy source to apply energy onto the ejected coalescing agent to cause the build material in contact with the ejected coalescing agent to coalesce and solidify.
