Here’s how to put the ‘fabric’ into fabricate, as ETH Zurich alumna and TU Delft Assistant Professor of Digital Fabrication Mariana Popescu explains.

Could a knitting machine revolutionise construction?

For her PhD, ETH Zurich alumna Mariana Popescu worked with the Block Research Group to show that it’s possible to use lightweight knitted textiles as a mold for concrete. Mariana discusses knitting machines, complex geometry, and why her PhD project needed two suitcases to get to Mexico.

This is her story.
