In automotive and other fields of application media transmitting components are made of plastics for reasons of weight and cost and complex, flow-optimized geometries are most desirable. Therefore, the laser sintering technology (SLS) is predestinated to manufacture these components as it offers a very high degree of design freedom and good mechanical properties. For industrial applications the long-term properties of the SLS material in contact with liquid media are important and were

Furthermore, laser sintering design guidelines for media transmitting components were developed. These guidelines for instance include the minimum wall thickness to ensure media tightness and strategies for the removal of powder from channels with a high length to diameter ratio.
