From Filament to Structure (2024-11)¶

This essay investigates the potential of fibre-reinforced polymers (FRPs) in the construction industry, emphasizing the role of additive manufacturing in advancing sustainable practices. By leveraging 3D printing technology, fibre filaments can be produced in a streamlined process, allowing for the creation of complex forms with reduced material use. The focus of this study is on both short and long fibre-reinforced filaments, particularly those incorporating natural and bio-based fibres, offering an alternative to traditional petrochemical-based materials. The study evaluates material properties of short-fibre PLA filaments reinforced with wood fibres, demonstrating their suitability for compressive structural elements. Long fibre filaments, produced with natural fibres like rayon, were also examined, with challenges identified around moisture sensitivity and filament consistency. Through an iterative design process, digital fabrication techniques were applied to optimize structural components such as columns and beams, leading to efficient material usage and improved performance in architectural applications. This research highlights the viability of integrating natural fibres into construction materials, promoting both material efficiency and environmental sustainability. However, further advancements are necessary to overcome technical challenges such as moisture absorption and mechanical limitations, particularly for large-scale applications. Continued development in multi-material deposition processes and fibre integration strategies is expected to enhance the potential of FRPs for broader architectural use, bridging the gap between innovative material science and practical construction techniques.
