Abstract
This paper describes the design-to-fabrication workflow of the Knit Tensegrity Shell project which will be exhibited at the IASS Symposium 2019. The workflow involves a) a digital framework of design, simulation, and analysis of the tensegrity shell, b) generation of CNC knitting machine
instructions for membrane fabrication, and c) production of a kit-of-parts assembly. Through multiple iterations of formfinding and FEA simulations, a shell design consisting of compressive carbon fibre struts tensioning a knitted textile membrane was materialised. This membrane element was
customised using CNC knitting to feature: (i) designated regions of yarn materials of varying stiffness as informed by stress concentrations; (ii) integrated pockets to hold the compressive struts; (iii) net-shaped textile based on an input design. Finally, construction details were rationalized
in order to insert the struts in an efficient manner and secure the novel structure.
