Beschreibung
Zusammenfassung:	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 metal powder build material and an agent distribution system to selectively deposit a binding agent on the metal powder build material in a pattern of a layer of a three-dimensional (3D) object to be printed. The additive manufacturing system also includes an ultraviolet (UV) energy source. The UV energy source, in a layer-by-layer fashion 1) cures the binding agent to join together metal powder build material with binding agent disposed thereon and 2) evaporates a solvent of the binding agent.
