摘要: 研究了3D打印工艺参数对ABS塑料手机外壳翘曲变形量的影响，结果表明，最佳的工艺参数组合为：供料段温度为200℃，压缩段温度为210℃，均化段温度为230℃，打印速率为40 mm/s，打印平台温度为60℃。对于打印温度参数，压缩段温度和均化段温度对制件翘曲变形量影响较为显著，供料段温度影响较小；另外，打印速率和打印平台温度也对制件翘曲变形量影响较为显著。在最佳工艺组合的工艺参数下制备了10组ABS塑料手机外壳，相应制件的最大翘曲变形量为0.056 2 mm，最低为0.051 2 mm，各组制件的翘曲变形量绝对误差均较小，最大仅为0.001 8 mm，最小为0 mm。10组实验的标准差为0.000 5。Abstract: The effect of 3 D printing process parameters on the warpage deformation of ABS plastic mobile phone shell was studied.Resultsshowed that the best combination of process parameters was when the temperature of feeding section was 200℃, the temperature of compression section 210℃, the temperature of homogenization section 230℃, the printing rate 40 mm/s, and the printing platform temperature 60℃. For the printing temperature parameters, the compression section temperature and homogenization section temperature had significant effects on the warpage of the workpiece, while the temperature of the feeding section had a little effect on the warpage; in addition, the printing rate and printing platform temperature also had significant influence on the warpage. Ten groups of ABS plastic mobile phone shell were prepared under the optimal process parameters. The maximum warpage deformation of the corresponding parts was 0.056 2 mm, and the minimum was 0.051 2 mm. The absolute error of each group of parts was small, with the maximum only 0.001 8 mm and the minimum 0.051 2 mm. The standard deviation of ten groups of experiments was 0.000 5.
