| Abstract: | An experimental study was carried out for selective laser sintering(SLS) of polystyrene and nano-Al_(2)O_(3) powder mixtures.The bulk polymer / Al_(2)O_(3) nano-composites with intact outline and no warping were successfully fabricated under proper operating parameter conditions ranging the appropriate combination of laser power from scanning speed.SEM pictures show that nano-sized Al_(2)O_(3) particles are uniformly located within polystyrene matrix.Some mechanical properties of sintered parts were tested.The results show that the maximal density,densification and notched impact ductility are 1.04 g/cm~(3),over 95% and 12.1 kJ/m~(2) respectively. |
