  Abstract

In this study, a unit hinge structure (UHG) and a multi hinge pattern (MHG) were developed using two different hardnesses of thermoplastic polyurethane (TPU) filaments and their compression behaviors were compared. It was analyzed that the modeling method, actual printing time and weight, and tensile and compression properties according to two different hardnesses of TPU filaments. As a result, three types of UHG in the form of a rectangular parallelepiped with constant hinge and frame thickness and height were developed, and based on this, three types of MHG were developed by tessellation. In the tensile properties, it was confirmed that TPU95A is a stiffer and more rigid material than TPU87A. In the case of UHG compression properties, the sample made of TPU87A did not show shear deformation, but the sample made of TPU95A showed the maximum strain at the 50% point regardless of the type. In the case of MHG compression properties, it was confirmed that the size and pressure of UHG are inversely proportional regardless of the filament, and the shear deformation appears well as the size increases. In the case of TPU95A, stronger pressure was required, which can be appropriately adjusted according to the user's experience.
