Patent ID: 8313939

Claim:
A method of making a molded part, comprising: forming a mixture of a fungal inoculum, a nutrient source for the fungal inoculum, and a liquid; injecting the mixture into a first mold cavity; sealing the first mold cavity against a second mold cavity; growing live mycelium from the fungal inoculum to fill the first and second mold cavities to form a first molded part; curing the live mycelium to terminate further growth; separating the first mold cavity and the second mold cavity; injecting a mycelium slurry over the first molded part in the first mold cavity; sealing the first mold cavity against a third mold cavity; growing live mycelium from the mycelium slurry to form a second molded part over the first molded part; and curing the live mycelium of the second molded part to terminate further growth and develop a dual mycelium molded part made up of the first molded part and the second molded part.
