An Exploratory Study to Examine Tensile Behavior of 3D Printed Knit Textiles

---

Abstract

This experimental study aimed to examine tensile behavior of 3D printed knit textiles using fused deposition modeling 3D printing method with thermoplastic polyurethane filaments guided by the ISO 13934-2:1999 grab method. Results presented that 3D printed knit textiles had a high tensile strength, ranging from 79.50 N to 117.63 N, that could bear multidirectional stress while being worn. While conventional knit textiles can extend up to 100%, the maximum elongation percentage of 3D printed knit textiles ranged from 300.43% to 444.45%, demonstrating their exceptional stretchability and possible application in the production of wearable items. The force-elongation curve of 3D printed knit samples was notably similar with conventional knit textiles, demonstrating the potential of 3D printed knit textiles to mimic conventional knit textiles in terms of responding to force. The findings provide critical insights for future researchers and designers to develop 3D printed knit textiles.
