WHY GROW A SURFACE? These prototypes for a mycoform surface system occupy the intersection of parametric CAD design and synthetic biology. Their multi-curved shapes are designed and cut digitally, but the segments are grown from strains of fungi into the specific 3D geometries of the piece. This low-tech, low energy process is pollution free, and contains a low embodied energy as part of a local ecosystem. The technology is easily transferable to the developing world. At the end of the useful product life cycle, Mycoform can be composted and safely reintroduced back into the environment, where it can be naturally biodegraded.
