Knitting instead of 3D printing: A research project by the Block Research Group (BRG) at ETH Zurich shows that knitted textiles are suitable as formwork for complex concrete shells and also reduce material, costs and working hours. KnitCandela is a sinuous concrete shell built on an ultra-lightweight cable-net and knitted formwork, with the knit brought to the site in two suitcases. Built at the Museo Universitario Arte Contemporáneo in Mexico City, the project is an homage to the shell builder Félix Candela (1910-1997). To reuse straight formwork elements, Candela used hyperbolic paraboloid surfaces (or “hypars”). With the same ambition to reduce construction waste, the cable-net and knitted formwork system expands the range of anticlastic geometries that can be built efficiently and economically.
