Design on printing parameters of flexible polylactic acid used in 3D printing fabric texture

为将聚乳酸材料应用于立体打印服装上,研究柔性聚乳酸材料的最佳打印参数,采用熔融沉积技术,通过在3D打印机中设置不同的打印温度、环境温度、分层厚度、填充速度、挤出速度,对比不同打印参数下熔融挤出细丝的效果,得到柔性聚乳酸材料的最佳打印参数:打印温度为205℃,环境温度为23℃,分层厚度为0.2 mm,填充速度为80 mm/s,挤出速度为130 mm/s。对建立的纬平针组织模型在最佳打印参数下进行打印,得到的立体打印纬平针组织打印效果良好,打印精度高,可看出线圈之间相互串套的关系,适合于立体打印服装。

In order to apply the polylactic acid（PLA） material to the 3D printing clothing and study the optimum print parameter of flexible polylactic acid material,fused deposition modeling technology was used.By setting the different printing temperatures,ambient temperatures,layer thicknesses,filling speeds and extrusion speeds,the effects of flexible PLA filaments were compared.The optimal printing parameters of the flexible PLA materials were as follows.The printing temperature is 205 ℃,the ambient temperature is 23 ℃,the layer thickness is 0.2 mm,the filling speed is 80 mm/s and the extrusion speed is 130 mm/s.The weft plain stitch is printed under the optimal printing parameters.The printed three-dimensional weft plain stitch has good printing effect and high printing precision.The relationship between loops of printed weft plain stitch could be found.The printed weft plain stitch is suitable for 3D printing clothing.
