Work Topic

Eggshell is a novel fabrication process for non-standard, reinforced concrete structures. It combines large-scale robotic 3D printing of formwork with simultaneous casting of a fast-hardening concrete. Its aim is to expand the geometrical possibilities of concrete, ultimately leading to material savings as well as enabling expressive architecture.
