Abstract
The customized 3D printer will enable us to make cost-effective and usable rapid prototypes of TPU (Thermoplastic Polyurethane) based NPT. The current article’s objective is to investigate 3D printing technique based on FDM using a DIY 3D printer and TPU based auxetic structures based on NPT (Non-Pneumatic Tyre). Auxetic structures were used in the current research, instead of air, to retain energy and have a cushioning effect, thereby providing passengers with a relaxing journey. A comparative analysis was carried out between three distinct cell geometries to develop simple NPT models. Three different structures considered for FEA-based software testing static loading conditions of a standard passenger vehicle. CAD models were generated and performed a static analysis on ANSYS software. Through FEA simulation, reentrant hexagonal type auxetic structure is the most suitable one for a city utilitarian vehicle.
