Design Tools for Earthen Architecture

Earth construction, rooted in millennia-old traditions, offers economic, sustainable, and cultural benefits, yet it has been marginalized in modern architecture. However, with the emergence of computational architecture, there’s potential for a revival. Extrusion-based Additive Manufacturing (AM) presents a disruptive technology, enabling layer-by-layer construction without formwork. While current research focuses on cementitious materials, there’s a shift towards employing earth in AM processes, marrying tradition with innovation to streamline construction while preserving environmental advantages. Yet, challenges persist, necessitating integration of tooling, material, and computational design. This study explores parameters for robotically controlled extrusion-based AM using locally sourced soil, offering insights into material adaptation, tooling selection, and printing tests. By marrying traditional wisdom with cutting-edge technology, this research lays the groundwork for ‘Computational Extrusion for Earth Construction,’ aiming to redefine architectural practice with sustainability at its core.
