In April 2021 WASP presented TECLA –the world’s first load-bearing 3D-printed earthen structure, sited in Bologna, Italy. The fluid, organic form articulated a spectrum of warm, visually stimulating and haptically sensual textures. TECLA was a collaboration between WASP and architect Mario Cucinella. The sophisticated geometries intrinsic to the material and structural performance of this poetic biophilic design were modelled and resolved using Rhino and Grasshopper plug-in; an industry standard computational/parametric design platform. The software is fundamental to the development of a novel design language for 3D-printed architecture, through the facilitation and translation of virtual models integral to mass-customisable forms and articulation.
