Morphology and Properties of Textiles Manufactured by Three-Dimensional Printing Based on Fused Deposition Modeling
Lee Sun Hee
In this study, the possibility of textile manufacture by 3D printing based on fused deposition modeling (FDM) was investigated. Among the various filaments that can be used for 3D printing, three polylactic acid (PLA) filaments and one thermoplastic polyurethane (TPU) filament was collected and then examined by dynamic mechanical thermal analysis (DMTA), differential scanning calorimetry (DSC), and a tensile test. An Stereolithograpy (STL) file with a 3D textile model was prepared and transformed into a G-code file using a G-code generator. The extrusion conditions for 3D printing were controlled by nozzle speed, nozzle temperature, thickness of the outer layer, height of the layer, and extrusion speed. Textiles manufactured by 3D printing based on FDM using PLA and TPU filaments were obtained. A 3D textile sample prepared using TPU filament was analyzed for morphology, and thermal and tensile properties, and the following results were obtained: melt temperature of approximately 204∘C, breaking load of 14 N, and elongation of 36%. Consequently, the applicability of 3D printing based on FDM for manufacturing textiles using TPU filament was confirmed.
