| description | In one example in accordance with the present disclosure, an additive manufacturing system is described. The additive manufacturing system includes a build material distributor to deposit powder build material on a surface and an agent distribution system to selectively deposit various colored fusing agents and an ultraviolet absorbing agent on the powder build material in a pattern of a layer of a three-dimensional (3D) object to be printed. An irradiation source selectively fuses powder build material with colored fusing agent disposed thereon. The additive manufacturing system also includes a controller. The controller, per location of the layer of the 3D object to be printed 1) determines an energy absorption at the location based on an absorptivity of colored fusing agents deposited at that location and 2) determines an additive manufacturing adjustment to be made at the location to bring the energy absorption at the location to a target level. |
