dc.description.abstractAdditive manufacturing (AM) of highly complex three-dimensional metal structures using selective laser melting (SLM) is increasingly gaining interest in numerous fields of application. The new design freedom combined with enhanced lightweight design methods shows an enormous potential, especially in the aerospace industry. Thereby, metal alloys with a high strength to weight ratio play an important role. Although several titanium and aluminium alloys have been SLM-processed successfully, the high strength-aluminium alloy EN AW 7075 remains a challenge. The major challenge in SLM processing of EN AW 7075 is the high sensitivity to hot cracks due to process related temperature gradients and rapid solidification. Preheating represents a promising approach to reduce temperature gradients and minimize shrinking between the layers. This investigation focuses on optimum SLM process parameters and reduction of hot cracking of EN AW 7075. In the first step, hot crack formation was evaluated from single track experiments to identify the most promising range of laser parameters. Subsequently, multi-layer parameter studies were carried using EN AW 7075 powder and preheating of up to 350 °C.de_CH
