Abstract

The present research considered the effects of different 3D printing parameters on the quality of 3D printed products. The parameters included printing direction, filament material and nozzle size. The quality assessment measures included surface finish and dimensional accuracy. Products were printed using FDM technology. A full factorial set of experiments were conducted. For each experiment, surface roughness and dimensional measurement were taken at different locations of the products. Experimental results showed that the small nozzle size results in better surface finish and fewer variations in Ra values. The adhesion between bed and products results in large variations in Ra values. The surface roughness of products is comparable to rough machining operations. Experimental results, also, showed that product dimensional accuracy is comparable to IT12 to IT16 manufacturing processes. Statistical analysis of results showed that the different printing parameters significantly affect the surface finish. For relatively larger dimensions, the material and nozzle size do not have a significant effect on dimensional accuracy.

3D打印产品的质量评估

本研究考虑了不同3D打印参数对3D打印产品质量的影响。参数包括打印方向、长丝材料和喷嘴尺寸。质量评价指标包括表面光洁度和尺寸精度。产品采用FDM技术打印。进行了一组全因子实验。在每个实验中，在产品的不同位置进行表面粗糙度和尺寸测量。实验结果表明，喷嘴尺寸越小，表面光洁度越好，Ra值变化越小。床层和产品之间的粘附导致Ra值的大变化。产品的表面粗糙度可与粗加工操作相媲美。实验结果也表明，产品尺寸精度与IT12至IT16制造工艺相当。统计分析结果表明，不同的打印参数对表面光洁度有显著影响。对于相对较大的尺寸，材料和喷嘴尺寸对尺寸精度没有显著影响。
