In order to improve the quality of sintering and make the settings of process parameters more quantitative,the optimization method of laser sintering process parameters based on response surface method is proposed.The size accuracy of laser sintering materials is designed as the optimization index.According to the response surface model framework and evaluation coefficient,the influence degree of various factors’individual and interaction on the size error rate of materials is analyzed.The degree is determined by the contour shape to create the process parameter quadratic regression fitting expression of the response surface method,so that the reliability of parameters is guaranteed and the optimization of laser sintering process parameters is realized.The results show that the method in this paper can obtain the influence value of the corresponding parameters and the optimal process parameters of the corresponding materials,so that the formed products have better accuracy and higher quality.
