This year's Architectural Association (AA) Summer DLAB program culminated in Weave.X, the final working prototype of three-dimensionally interwoven concrete structures. Designed and fabricated by 21 participants from 11 countries in July and August, the prototype explores computational design, geometry rationalization, material behavior, and robotic fabrication as applied to concrete and robotic rod-bending techniques. The result is a network of self-supporting concrete branches that envelop an amorphous enclosure.

The preliminary phase of the research involved using Grasshopper to generate a network of interwoven elements and developing an automated fabrication process to bend steel reinforcement bars to custom shapes. Participants analyzed established rod bending strategies to develop an approach that would ...
