3D printing onto pre-stretched fabric has recently gained popularity as a technique to create self-shaping textiles which can deploy into freeform shapes when the fabric is released. The morphing behaviour of this composite material is due to a combination of intrinsic and extrinsic geometric transformations, the deposited plastic is both frustrating the metric of the textile and forming a bilayer with its substrate.  

In this talk, I will show how to leverage these observations to create specific geometries with self-shaping textiles, by printing small and repetitive elements which can influence both the metric of the deployed surfaces and their bending behaviour. We will see that these self-shaping textiles can be either designed by form-finding for a specific layout using physics-based simulations, or by form-prescribing: using an optimization algorithm we can find the optimal layout to be printed to reproduce a given 3D shape.
