| summary |
This project, Symbiont Substrate, presents a bio-digital fabrication method for large-scale 3D printing of bioreceptive clay modules with robotic automated colonization of lichen communities. The workflow articulates fieldwork collection of lichen samples in an urban environment, Manhattan, New York City, followed by lab in-vitro culturing for growth tests on 3D printed ceramic substrates. The computational strategy employs procedural growth algorithms, including L-systems branching logics, to create functional bio-receptive physical features and textures in the extruded clay topographic surfaces. The chemical properties of the ceramic substrates are controlled by using a clay type with a neutral pH value, and by firing at a low temperature to increase surface roughness and porosity in order to retain moisture and nutrients distribution. A robotic inoculation method using living lichen cultures was developed to create precise large scale patterns of lichen growth in the overall ceramic columnar assembly. These are intended to serve as air quality biosensors, and to increase biodiversity within urban environments. |
