  Abstract

In this study, a 3-pointed star shape was manufactured using lightweight thermoplastic polyurethane under FDM 3D printing process conditions. Specifically, we modeled 3-pointed star-shaped auxetic structures with different thicknesses and samples obtained through a FDM 3D printing process using LW-TPU materials. Their morphologies, specific gravities, thermal properties, and compression characteristics were investigated under the nozzle temperatures of 200 , 220 , and 240 . The results of LW-TPU filaments analysis confirmed the presence of microspheres with foaming performance at extrusion temperatures above 200 . Regarding the compression characteristics of the 3-pointed star-shaped materials, it was found that higher printing temperatures were associated with lower compressive deformation rates and higher compressive strengths. This study shows that 3-pointed star-shaped structures having various compression characteristics can be 3D printed using LW-TPU material and specific nozzle temperatures.
