초록

The objective of this study was to develop lace-style 3D printed textiles using thermoplastic polyurethane filaments for 3D printing by fused deposition modeling.
Composite voile textiles with lace motifs of different sizes were produced by various roller press processes. The textiles were characterized according to their tensile behaviors, tensile characteristics, and stiffnesses. The analysis of tensile characteristics revealed that the 3dLaceM1 textile with a big pattern had a maximum load of 13.2 kgf and an elongation of 274.3%. Moreover, as the size of the lace motif decreased, the maximum load value tended to decrease, while the elongation value tended to increase. The composite 3D-printed lace/voile textile (3dLaceM1/voile), which was produced by a roller press, had a maximum load of 35.4 kgf and an elongation of 383.9%. The initial modulus of 3dLaceM1/voile was 20.56 kgf/mm2, which was more than six times that of the 3D-printed lace textile that was produced by the roller press process. The stiffness of the 3D-printed lace textile tended to decrease with the size of the lace motif. In addition, the 3D-printed lace that was produced with the roller press process exhibited more flexible characteristics. Furthermore, the stiffness of the composite 3D-printed lace/voile textile was higher than that of the conventional 3D-printed lace textile. Thus, the tensile characteristics and stiffnesses of textiles could be customized for specific uses through process control of the 3D-printed lace.
