Abstract

A process for producing a metallic component with an opening or a hollow space by selective laser sintering or laser melting includes melting a metallic powder in layers at appropriate cross-sectional regions by using laser radiation. After the laser sintering or laser melting process, the component is subjected to a fracture splitting process, in which the component is fractured into at least two fractional parts along a fracture line and then the at least two fractional parts are connected to one another at the sites of fracture to form the component. The fracture line contacts or passes through the opening or the hollow space.
