摘要 |
The invention relates to a method for producing a component through selective laser melting and to a process chamber (11) for carrying out the method. According to the invention, the selective laser melting by way of a laser (17) is also used for producing coating areas (25) of the component (14) being produced, said coating areas having a composition that differs from the composition of the powder (16). This is accomplished by intermittently introducing a reactive gas (27) that reacts with the powder material or that produces a material on the component (14) from precursors present in the reactive gas. In the process chamber according to the invention, an additional feed line (28a, 28b) is provided for introducing reactive gas, said feed line permitting the feeding of the reactive gas if possible close to the laser (17). |
