6.500 silkworms in Axis – MIT’s Silk Pavilion
Axis, Japanese-English magazine on design, highlights MIT’s Silk Pavilion.
MIT’s Silk Pavilion explores the relationship between digital and biological fabrication on product and architectural scales.The primary structure of the pavillion was formed by 26 polygonal panels made of silk threads laid down by a machine. Inspired by the silkworm’s ability to generate a 3D cocoon out of a single multi-property silk thread (1km in length), the overall geometry of the pavilion was created using an algorithm that assigns a single continuous thread across patches providing various degrees of density.
A swarm of 6,500 silkworms was then positioned at the bottom rim of the scaffold spinning flat non-woven silk patches as they locally reinforced the gaps across CNC-deposited silk fibers. Following their pupation stage the silkworms were removed. Resulting moths can produce 1.5 million eggs with the potential of constructing up to 250 additional pavilions. Affected by spatial and environmental conditions including geometrical density as well as variation in natural light and heat, the silkworms were found to migrate to darker and denser areas.
Desired light effects informed variations in material organization across the surface area of the structure. A season-specific sun path diagram mapping solar trajectories in space dictated the location, size and density of apertures within the structure in order to lock-in rays of natural light entering the pavilion from South and East elevations.
The central oculus is located against the East elevation and may be used as a sun-clock. Parallel basic research explored the use of silkworms as entities that can “compute” material organization based on external performance criteria. Specifically, we explored the formation of non-woven fiber structures generated by the silkworms as a computational schema for determining shape and material optimization of fiber-based surface structures.
