Abstract :

This abstract summarises the project named ‚??Development of a multifunctional case for aerospace electronics, which special focus on power electronics and power supply‚?Ě. This project was realised by the Blue Dot Solutions company and co-financed by the (Polish) National Research And Development Centre. Several different types of lattice materials fabricated via the SLS method were designed and examined. Initially, these structures were simulated, a then were sintered via the SLS method. The material used for this project was ‚??Alumide‚?Ě, whic is a 7:3 mix of PA12 polyamid and aluminium. The main properties of this metallic-looking material are: high stiffness and very good characteristics for post-processing. Pieces of Alumide materials can undergo various post- treatment techniques, such as sanding, polishing or grinding. Studies and numerical simulations were done on several basic isotropic cells. Five of them were analysed further: 1e, 1f, 1h, 2b, 5 (il. 1). The goal of the analisis was to determine the equivalent of thickness in dependence to structure of a single cell. The numerical analysis was done for thermal and thermodynamical cases (il. 2).
