Due to the limited mechanical characteristics of the materials which can currently be processed using industrially available Rapid Prototyping techniques, work is currently being undertaken to develop technologies of manufacturing metallic parts directly from CAD. These include Laser Generating and Selective Laser Sintering. Both have the similar process characteristics in which the workpiece is created not by removal of materials, but by layerwise deposition and local melting or sintering of powder materials without part-specific tooling. Due to the excellent surface and high form accuracy achievable with Laser Generating this technology offers an interesting alternative to the conventional time consuming processes for manufacture of the tools required for limited production runs. With respect to Selective Laser Sintering, a test facility is developed which enables experimental investigations on direct sintering of low and high melting metallic powders. Great application potentials of Selective Laser Sintering are expected in prototyping of tools, especially molds and dies.
