Analysis of strength properties of 3D printed lightweight structures made of AlSi10Mg material

Original language description

The main aim of this article is to compare two approaches to decreasing the overall weight of components by using additive manufacturing from AlSi10Mg alloy. This optimization is advantageous as it lessens both the production time of parts (components) and overall costs, in key industries such as aviation. The first method used to reduce the weight of a structure is the implementation of lattice structures, which replace filled parts with selected structures of different shapes, while maintaining key properties of the original structure. The other method to decrease weight is the topological optimization of prepared samples. In this article, these two options have been compared. The specially designed sample was first optimized topologically. Subsequently, it was lightened using selected structures (Octet truss and Rhombic dodecahedron) in SW Magics with different lattice parameters. These samples were then printed using DMLS technology from AlSi10Mg on the ConceptLaser M2 Cusing system. The material used was analysed by SEM, and a particle size distribution was also performed. Furthermore, a three-point bending test was performed on the bodies produced in this way. The results of this test were analysed and evaluated in terms of load (bending force), depending on the type of sample and the volume/weight saved.
