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 $20.56kgf/mm^2$, 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.

문제 정의

This study intended to determine the producibility of lacestyle textile through an application of 3D printing technology. Three kinds of lace-style 3D modeling of different sizes of each lace motives were developed and 3D printed lace was produced by employing an FDM 3D printer using TPU filament for print out under the following printing conditions:nozzle temperature, 230 oC; printing speed, 50 mm/s; 100% of filling, and layer height, 0.

제안 방법

FDM 3D FINEBOT printer was used for test printing. Following control conditions of nozzle temperature of 230 oC,printing speed of 50 mm/s, 100% of filling, and layer height of 0.2 mm were employed for test printing of the 3D printer.
Properties of 3D printed lace style textiles wereanalyzed. In this study, 3D printed lace was fabricated using TPU filament for the FDM 3D printer. Roller press process was then applied to the developed 3D printed lace to fabricate composite fabric of 3D printed lace/voile textile.
Values of initial modulus of elasticity appeared to decrease in accordance with the decreasing sizes of each pattern, suggesting that the flexibility of textile increased accordingly. Tensile characteristics of 3D printed lace that underwent the roller press process were also analyzed. Values of maximum load appeared to increase in accordance with increasing sizes of each pattern while the value of elongation tended to be decrease accordingly.

The roller press process was employed and run with operating speed of 6.
With an application of adhesive spraying once at room temperature,the roller press processing was then performed to produce composite 3D printed lace/voile textile. To evaluate characteristics of the resulted 3D printed lace, tensile behaviors, tensile characteristics, and stiffness of each textile were analyzed for 3D printed lace that underwent roller press processing and the final composite 3D printed lace/voile textile. The following results were obtained.
Roller press process was then applied to the developed 3D printed lace to fabricate composite fabric of 3D printed lace/voile textile. stiffness, tensile behavior, tensile strength, and elongation of 3D printed lace, 3D printed lace underwent the roller press processing, and composite 3D printed lace/voile textile were then analyzed. Based on obtained results, the possibility of application as a fabric for women’s dresses and blouses (KSK 3823) is then discussed.

대상 데이터

Autodesk 123D was used for modeling lace style 3D textile with the following dimensions: 150 mm×100 mm×1.3 mm.

이론/모형

Stiffness Test: The cantilever method was used according to KS K 0539 to determine tensile strength and elongation for which the weight of unit area of each sample was obtained. The sample was placed on a stand equipped with slant surface.

성능/효과

During printout of 3D printed lace, values of drape stiffness tended to decrease in accordance with decreasing size of each pattern and increasing number of lace motives whereas values of drape stiffness of composite 3D printed lace/voile textile that underwent the roller press process tended to increase slightly. The analysis of drape stiffness and flex stiffness revealed that values of stiffness tended to decrease in accordance with decreasing size of each lacemotive that fostered flexible characteristics. Thus, an application of roller press process seems to result in an attainment of slanderer, thinner, and tougher 3D printed lace depending on the extent of reduction in thickness.
