Strategies for Growing Large-Scale Mycelium Structures

Biomimetics (Basel). 2022 Sep 11;7(3):129. doi: 10.3390/biomimetics7030129.

Abstract

Fungi-based materials (myco-materials) have been celebrated and experimented with for their architectural and structural potential for over a decade. This paper describes research applied to assembly strategies for growing large building units and assembling them into efficiently formed wall prototypes. A major concern in the development of these two fabrication strategies is to design re-usable formwork systems. La Parete Fungina demonstrates two undulating wall units standing side-by-side, each composed of seventeen myco-welded slabs. L'Orso Fungino revisits the in situ monolithic fabric forming of units that are repeated, stacked, and post-tensioned. Although the design and research presented in this paper focuses on overcoming the challenges of growing large-scale building components, this work also touches on issues of accessibility and technology, economic and logistical systems needed for building-scale applications, and material ethics of energy and waste associated with emerging biomaterial production.
