A Review on the Fused Filament Fabrication of Lightweight Components

Fused filament fabrication (FFF) has become a de facto choice to fabricate complex-shaped polymer components. Recently, the potential of this technique has been explored in the fabrication of lightweight components due to its capabilities. Various articles have been reported based on the use of FFF process for the development of lightweight structures. In order to identify the current status, challenges, and research gaps in this domain, a thorough review of the existing articles is needed. Therefore, the present article aims to review the development of lightweight components through FFF. Different strategies adopted to develop lightweight components are highlighted with the challenges and research gaps. The outcome of the study may be useful in developing components for weight-sensitive applications using FFF process.
