Methods for Earth-Based Falsework in Multi-Material Additive Manufacturing at an Architectural Scale

This study delves into the promising potential of multimaterial Additive Manufacturing (AM) for large-scale architectural applications. It specifically focuses on the innovative integration of dissolvable and reusable, single-sided falsework within 3D-printed structures. Unlike traditional dual-sided moulds that limit design capabilities and increase labour, this method effectively utilises earthbased falsework that not only can be reused for subsequent prints but also significantly contributes to minimising waste and reducing overall material requirements. Through this lens, the research tackles the inherent challenges in creating complex, non-self-supporting forms, while also underscoring effective strategies aimed at optimising the deposition of structural materials both alongside and on top of the falsework. In its detailed analysis, the study examines various factors such as nozzle angles, different printing directions, and the implementation of dynamic adjustments. Ultimately, this research demonstrates how multi-material Additive Manufacturing can adeptly overcome the inherent limitations presented by mono-material approaches, thereby offering enhanced design flexibility, sustainability, and operational efficiency. This paves the way for innovative advancements in architectural design and construction practices, showcasing the future potential of AM in creating sustainable and adaptive structures.
