Processing of Aluminum Alloy EN AW 7075 Using Selective Laser Melting: Initial Study

Popis výsledku v původním jazyce

Selective Laser Melting (SLM) is an additive manufacturing process, that uses a fine metallic powder to produce complex parts. Unfortunately, the range of SLM processed materials is limited by available materials in powder form and for many materials process parameters have not been defined. Currently, about four aluminum alloys has been successfully processed. The aim of this paper was description the influence of the process parameters to the material processability of high strength aluminum alloy EW AW 7075 by SLM. Wide range of process parameters (100-400 W laser power and 300-1400 mm/s scanning speed) were examined to find the optimum processing parameters producing homogeneous material. In this study, maximum relative density of 96.2 % was achieved. However, typical hot cracks, which appears during welding process of aluminum alloy EN AW 7075, was observed in all parts. Cracks were reduced but were not eliminated.
