Abstract

This paper investigates the potential of clay extrusion as formwork for casting customized and building-scale fiber-reinforced concrete elements. Customizable shapes are produced using clay as cheap, sustainable, and easily demoldable formwork, extending its printable height limit. The coupled incremental clay 3D printing and concrete casting process allows the layered casts to start curing and reduces the hydrostatic pressure from concrete. The concluding case study, the Cocoon, demonstrates the method's capability to achieve building-scale height, integrate openings, and create complex surfaces. The introduced method seeks to challenge techniques and materials for 3D-printed formworks, demonstrating the ability to reduce the environmental impacts of concrete construction without compromising the complexity and time efficiency of bespoke elements.
