Abstract Scope |
Airless or non-pneumatic tires (NPTs) can operate without internal fluidic pressure, offering a promising low-maintenance and environmentally friendly alternative to their pneumatic counterparts. These new tires concepts open a wide range of design possibilities, which has resulted in a diverse array of proposed solutions. Existing NPT concepts in literature often pursue intricate functional designs that can be challenging to manufacture. Taking advantage of the design freedom offered by additive manufacturing technologies, techniques such as fused filament fabrication (FFF) have recently been used to produce NPTs for diverse applications. In this study, the authors explore NPTs design features within the context of FFF tires made with thermoplastic elastomers, with a focus on bicycle-sized wheels. Following an analysis of the current state-of-the-art of FFF NPTs, the authors propose a processing workflow that helps identify how process-related parameters and design methodologies might interact with different stages of the tire development process.Above all, the authors believe that the early consideration of manufacturing constraints and design for additive manufacturing inputs allows a faster prioritization of initial design proposals. This analysis aims to elucidate suitable design decisions for developing NPTs using FFF and accelerate the study and adoption of these newly proposed products. |
