Abstract

Abstract: To clarify the effect of selective laser sintering process parameters on the quality of sintered parts made from polystyrene (PS)/polyester fiber (PET)/glass fiber (GF) ternary composites, three process factors including thickness, scanning speed and distance were selected for the coupling experiment, and the variation law and reasons of dimensional accuracy and bending strength were analyzed and summarized. The size accuracy in the x and y directions of the sintering parts was seldom affected by the variation of process parameters, whereas there was a significant influence on the accuracy in the z direction. The bending strength was mainly influenced by the laser energy density during the forming process. The results indicated that the bending strength of the sintered parts decreased with an increase of dimensional precision. This result provides an experimental evidence for the selection of technological parameters to improve the quality of the sintered parts.
