Abstract

In an example implementation, a method of fusing layers of 3D parts includes forming a layer of build material, and selectively applying a liquid agent onto the layer of build material to define a part layer of a 3D part and a sacrificial layer of a sacrificial part. The method includes, in a single pass of a thermal energy source over the layer of build material, applying fusing energy to the sacrificial layer, sensing a temperature of the sacrificial layer, adjusting a power level of the thermal energy source based on the sensed temperature, and applying fusing energy to the part layer with the adjusted power level of the thermal energy source.
