Abstract: According to some examples, a method comprises measuring, using a detector, a temperature of at least a portion of a layer of build material formed on a print bed associated with an additive manufacturing apparatus. The additive manufacturing apparatus may include a heating module to direct heat towards successive layers of build material during a series of successive passes over the build material. The method may further comprise determining, using a processor, based at least in part on the measured temperature, a duration that the heating module is to wait before performing a pass over the build material, and a speed at which the heating module is to travel over the build material.
