Scaling-up Biodesign Weaving logic of mycelium-based-composite architecture

Mycelium-based composites (MBC) proved to be the one of the first biofabricated materials that can be implemented directly in architectural and interior design settings.The study presents a novel method of MBC biofabrication, which functionalises filaments of MBC stabilised by textile-net tubes as weft, woven on the cotton string warp.Cotton strings are arranged spatially by hanging to allow for three-dimensional formations and physical gravity-based finding of the optimal form.The demonstrators are the subsequent upscaling attempt after initial small-scale (30-60 cm height) proof-of-concept prototypes (Biale et al., 2026), which proved feasible.The goal of the study was to understand better the interplay and interdependencies of the process's parameters in all of the biofabrication phases (filament production, assembly, water transfer and skin formation during growth, contamination prevention, drying and shrinking) in the case of bigger demonstrators 120 cm height) cultivated in semi-sterile conditions.The study has developed an understanding of which aspects become more significant as the element's size increases and has verified the feasibility of this biofabrication method for future upscaling efforts.
