为了提高熔融沉积制造(FDM)成型制品的质量,采用正交试验的方法研究分层厚度、成型室温度、填充间隔以及扫描次数对丙烯腈–丁二烯–苯乙烯(ABS)制品表面粗糙度和拉伸强度的影响,通过对测量数据进行极差和方差分析,评估出各工艺参数对制品表面粗糙度和拉伸强度的影响顺序及显著性水平,给出了最优化工艺参数组合。实验结果表明,各工艺参数对制品表面粗糙度和拉伸强度的影响程度存在差异,其中对表面质量影响程度为:分层厚度>成型室温度>填充间隔>扫描次数,最优化参数组合为成型室温度80℃,分层厚度0.17mm,填充间隔6,扫描次数2。对拉伸强度影响程度为:分层厚度>填充间隔>扫描次数>成型室温度,最优化参数组合为成型室温度80℃,分层厚度0.30mm,填充间隔4,扫描次数4。研究内容对优化3D打印参数、提高制品成型质量具有一定的指导意义。

Influence of Printing Parameters on Properties of Fused Deposition Modeling ABS Samples

To improve the molding quality of fused deposition modeling (FDM) products,the influence of layer thickness, molding room temperature,filling gap and scanning times on the surface roughness and tensile strength of ABS printed products was studied by using the orthogonal experimental design method. By analyzing range and ANOVA of the measured data,the influence order and significance level of each process parameter on the surface roughness and tensile strength of printed products were evaluated,and the optimal combination of process parameters was given. The experimental results show that the influence of various process parameters on the surface roughness and tensile strength of printed samples is different. The sequence of the magnitude of effect of the four factors on the surface quality is as follows :layer thickness,molding room temperature,filling gap and scanning times. The combinations of optimal levels are as follows :molding room temperature 80℃,layer thickness 0.17 mm,filling gap 6 and scanning times 2. The sequence of the magnitude of effect of the four factors on the tensile properties is as follows :layer thickness,filling gap,scanning times and molding room temperature. The combinations of optimal levels are as follows :molding room temperature 80℃,layer thickness 0.30 mm,filling gap 4 and scanning times 4. The research has certain guiding significance for optimizing 3D printing parameters and improving the molding quality of products.
