Abstract The composite powders of nylon 12 (PA12) and polystyrene (PS) with different mass fraction were prepared by mechanical mixing method and then work pieces of the composite powders was prepared by selective laser sintering(SLS). The effect of the PA12 / PS ratio on the mechanical property, dimensional accuracy and fractured microcosmic morphologies of the sinteredwork pieces were investigated. The results show that when the mass fraction of PS exceeds 40% the mechanical properties of the sintered specimens decreased obviously and when mass fraction of PS is 20% the tensile strength, breaking elongation, flexural strength and flexural modulus are increased by 7.08%, 10.19%, 6.51% and 8.89%, respectively in comparison with the sintered specimens of PA12. And the dimensional accuracy was also increased.
