Fabricated panel
A self-supporting composite material is made with a shape conforming to the shape of an enclosure within which the composite material is incubated and molded. In on embodiment, a lid with at least one extrusion is placed over the enclosure to form a void in the final product corresponding to the extrusion. In another embodiment, a tool with extruded features is pressed into a face of the product in the enclosure to mold features into the finished product.
1. A method of making a self-supporting composite material comprising the steps of
creating an engineered substrate comprised of a nutrient source and at least one of discrete particles and fibers;
disposing the substrate within an enclosure in an amount to fill said enclosure;
inoculating the substrate within the enclosure with an inoculum containing a desired fungi strain;
growing the desired fungi strain through the engineered substrate within the enclosure for a time sufficient for said fungal strain to digest said nutrient source, to grow hyphae and to allow said hyphae to form a network of interconnected mycelia cells through and around said at least one of discrete particles and fibers thereby bonding said at least one of discrete particles and fibers together to form a cohesive whole with a shape matching the internal shape of said enclosure;
compressing a tooling piece with at least one protrusion into at least one face of the engineered substrate during growth of said fungi strain to forcefully mold a corresponding feature to said protrusion into the engineered substrate and resultant cohesive whole; and
thereafter removing the cohesive whole from said enclosure and drying the cohesive whole.
