Abstract: In one example, a method for printing a three-dimensional (3D) object is described. The method may include a processor depositing a layer of a sinterable material on a support member, and preheating the layer of the sinterable material using a moveable radiation source. The method may further include the processor depositing a fusing agent on an imaged area of the layer of the sinterable material and fusing the imaged area of the layer of the sinterable material using the moveable radiation source.
