A component is produced through selective laser melting of a powder material in a process chamber using a laser which is also used for producing coating areas of the component. The coating areas have a composition that differs from the composition of the powder material. This is accomplished by intermittently introducing a reactive gas that reacts with the powder material or that produces a material on the component from the precursors present in the reactive gas. In the process chamber, a feed line may be provided for introducing the reactive gas close to the laser. |
