Samenvatting

In this work, we study different rheological and thermal phenomena present during laser sintering of two polystyrene (PS) particles using fully resolved numerical simulations. In our analysis, we varied the laser power, the initial temperature and the thermal convection coefficient, used different rheological descriptions for the flow behavior and in addition studied the effect of the substrate (used in the experiments) on the temperature distribution of the system. Although we are not able to fully describe the results of the experiments with our simulations for the given parameter set, we obtained important insights in the significance of thermal initial and boundary conditions by systematically studying the sintering process.
