摘　　要：为了缩短熔融沉积成型(FDM)工艺的成型时间并改善产品的力学性能,采用FDM工艺方法对聚对苯二甲酸乙二醇-1,4-环己二甲醇酯(PETG)和丙烯腈-丁二烯-苯乙烯(ABS)两种线材进行3D打印,以成型时间、拉伸强度和拉伸弹性模量为优化指标,设计了基于正交试验法的三因素(打印速度、分层厚度、填充率)四水平的工艺参数优化方案。结果表明:PETG/ABS复合制件最优力学性能的参数组合是A4B1C3,即打印速度为30 mm/s、分层厚度为0.1 mm、填充率为75%。验证试验表明,拉伸强度为44.73 MPa、弹性模量为758.12 MPa、成型时间为113 min,优化参数后明显改善了力学性能,对双材料打印制品的生产具有一定的指导意义。In order to reduce the printing time of the fused deposition molding(FDM)process and improve the mechanical properties of the product,the FDM process method was used to 3 D printing the PETG and ABS wires,with the molding time,tensile strength and tensile elastic modulus as the optimization indicators.Designed a three-factor four-level process parameters(printing speed,layer thickness,filling rate)based on the orthogonal test method.The results show that the optimal mechanical property parameter combination for PETG/ABS composite parts is A4 B1 C3,that is the printing speed is 30 mm/s,the layer thickness is 0.1 mm,and the filling rate is 75%.Through experimental verification,the tensile strength is 44.73 MPa,the elastic modulus is 758.12 MPa,and the molding time is 113 min.After optimizing the parameters,the mechanical properties are significantly improved,which has certain guiding significance for the production of bi-material printed products.
