Abstract
A process produces a 3-dimensional component (16) by selective laser melting (SLM), in which the component (16) is formed on a foundation with a surface, e.g., a platform (10) or a support, which in particular is a component of the same type which has already been produced previously, by successively melting layers of a first metal powder to form a sequence of stacked layers. The process is substantially simplified and made more flexible by virtue of the fact that the separation of the finished component (16) from the surface of the platform (10) or the support thereof is simplified by providing a separating layer (11) between the component (16) and the platform (10) or the support, this separating layer making it possible to separate the finished component (16) from the platform (10) or the support without damaging the finished component (16).
