Mathematically generated and inspired by cellular networks, the PolyThread installation is a freestanding inhabitable form featuring knitted lightweight, high-performing, formfitting and adaptive materials. The digitally knitted fabric structure is held in tension with freestanding integrated fiberglass tubing. How do you knit and braid a building? Could a building be as lightweight as air? PolyThread features novel formal expressions that adapt to changes in the environment through formfitting and high-performance lightweight structures. The installation consists of a harder outside construction and softer, organic inner material. An inner structure of textile-based whole-garment knit elements absorbs, collects and delivers light as the materials react to variegated light sources and the presence of people through embedded shadows. Material response to sunlight as well as physical participation are integral parts of our exploratory approach to the subjects of beauty and adaptive architecture. The knit structure is composed of solar active and photoluminescent yarns. This project aims to engage a new material practice and next steps in digital fabrication in architecture through the production of models and prototypes via cutting-edge parametric and associative software that interface fabrication technologies in related, but alternative disciplines. Advancements in weaving, knitting and braiding technologies have brought to surface high-tech and high-performance composite fabrics. These products have historically infiltrated the aerospace, automobile, sports and marine industries, but architecture has not yet fully benefitted from these lightweight freeform surface structures. PolyThread features knitted textile structures at the scale of a small pavilion.
