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.
