Selective laser melting offers the possibility of manufacturing parts with complex geometries and a wide range of materials. Besides steel, aluminum or titanium alloys for which the process has been studied extensively, copper alloys are of great importance especially due to their unique physical properties. Facing difficulties such as high thermal conductivity, low absorption and resulting poor reproducibility, there is still a great need to optimize the manufacturing process and to describe the influence of the process parameters on the component quality. In this study the influence of laser power, scanning speed and hatch distance as well as interactions of these parameters on the mechanical properties and the relative density were investigated for the bronze CuSn10 using an industrial plant (Yb-fiberlaser, power: 250 W, beam diameter: 40 μm). The parameters are configured according to Design of Experiments enabling an efficient and economical way of evaluating the occurring effects.
