Utilization of the DMLS technology in manufacturing of tools and moulds designed for injection and casting ranks among significant possibilities of use. The main advantage in case of DMLS in comparison to conventional methods rests in the fact that manufacturing time does not depend on geometrical complexity of shaping part of the mould. In case of low volume or prototype moulds it is advantageous to use a concept of combination of shaping intermediate pieces inserted in universal frames and as material the DM 20 alloy on bronze basis the service life of which in case of such application is several thousand pieces.
