Position

In Nature―where shape is cheaper than material―one often finds load-resisting structures that combine multiple systems to accommodate for constantly shifting forces over time. Contrary to traditional manmade structural design, where beams and columns are often composed of homogeneous materials, many natural structures exhibit heterogeneity in both shape and material composition.

Advances in digital fabrication and robotic manufacturing over the past decade have enabled the rapid production of highly customized structural components, yet structural systems in the natural world remain superior in their performance.

Process

These projects apply Mediated Matter’s ongoing research into biologically augmented digital fabrication with silkworms and eusocial insect communities to product, architectural, and possibly urban, scales. Many insect communities present collective behavior known as “swarming,” prioritizing group over individual survival, while constantly working to achieve common goals.

Often, groups of these eusocial organisms leverage collaborative behavior for relatively large-scale construction. For example, ants create extremely complex networks by tunneling, wasps generate intricate paper nests with materials sourced from local areas, and bees deposit wax to build intricate hive structures.

Design templating techniques have proven to be an interesting approach to interface with biological organisms. Specifically, our work with silkworms in Silk Pavilion laid the foundation for the novel paradigm of a bio-homeomorphism, which describes continuous deformation and alteration of a structure, topological space, or geometric object by biological agents, such as silkworms.

For example, the fabrication of thread-based membranes and panels is typically constrained by the limitations of the underlying scaffold in which it is constructed. However, bio-homeomorphic structures feature various strategies for conditioning the behavior of the ‘agent’ that will, in its turn, condition the structure.

Policy

The system and tool offer a novel form of fabricating membranes in a dynamic manner, one that can adapt to different stimuli from the environment or other additional agents. They can be seen as a step towards an ideal adaptable approach for fabrication of meshes, suggesting that compromises need to be made in the amount of control designers have over the outcome of the process, so that we utilize design tools but also reconceive the way we perceive our interference in the process itself.

It is still being explored in a larger scale but has yielded promising results so far, not only with silkworms but in projects we have designed centered around ants and bees.
