Abstract
The present disclosure provides methods of three-dimensional printing, including iteratively applying individual build material layers of polymer particles having a D50 particle size from about 20 μm to about 150 μm to a build material, and based on a three-dimensional object model, selectively applying a fusing agent onto the individual build material layers to form individually patterned object layers of the three-dimensional object and selectively applying a pore-promoting agent onto the individual build material layers at a discrete location of the individually patterned object layers to form a pore-generating region therein. The method also includes exposing the build material to electromagnetic energy to provide selective heat fusing of the polymer particles and to generate and displace molten polymer leaving a localized void having a void size from about 1 mm to about 20 mm.
