Abstract:

In order to study the structure of weft plain knitted clothing fabrics produced by 3D printed, predict its printing effect and improve the digital and intelligent production of knitting fabrics, 3D printing technology was applied to the design and production of knitting fabrics. 3ds Max software was used to model the weft plain knitted fabric based on the NURBS curve modeling method and the Peirce loop model. The visualization of 3D printed weft plain knitted fabric was achieved and the printing effect was able to be predicted through simulation. Repetier-Host software was used to slice the simulated 3D printed weft plain knitted fabric model. The printing parameters were set and the model slice data was printed by fused deposition modeling technology, the 3D printed weft plain knitted fabrics were obtained. The results show that the effect of the printed fabrics is highly consistent with the simulated effects, and the intermeshing relationship between the loops is obvious. The printed fabrics are smooth and flat and the printing accuracy is high. The printed fabrics are environmental friendly fabrics.

Key words: weft plain knitted structure, three-dimensional simulation, fused deposition modeling technology, 3D printed fabric, polylactic acid material
