摘要
翘曲变形是影响FDM 3D打印制件质量的一个重要因素。实验以PLA/木粉复合材料丝材为成型原料打印试样,通过正交实验研究了喷嘴温度、平台温度和层厚对试样翘曲量的影响。研究结果表明,三因素中对翘曲量的影响依次是层厚>喷嘴温度>平台温度,当喷嘴温度在190℃~200℃,平台温度在50℃~80℃,层厚设置为0.2mm^0.3mm,打印的试样翘曲量比较小。这一点在正交实验中当喷嘴温度190℃,平台温度60℃,层厚0.2 mm时,试样的翘曲量达到最小为0.1mm,得到验证。
The warpage is an important factor that affects the quality of FDM 3D printing.In the experiment,PLA/wood powder composite wire was used as the raw material to print the sample.The effects of nozzle temperature,platform temperature and layer thickness on the warpage of the sample were studied by orthogonal experiment.The results show that the influence of the three factors on the warpage is layer thickness>nozzle temperature>platform temperature.When the nozzle temperature is 190℃~200℃,platform temperature is 50℃~80℃,and the layer thickness is 0.2 mm^0.3 mm,the warpage of the printed sample is relatively small.In the orthogonal experiment,when the nozzle temperature is 190℃,the platform temperature is 60℃,and the layer thickness is 0.2 mm,the minimum warpage of the sample is 0.1 mm,which is verified.
