Mycelium Biofabrication


So, I don’t work for ecovative and they aren’t paying me to say this, but i’ve always been really passionate about what they do. I wanted to introduce everyone to the possibilities of their products.

there’s the board:

and the mycofoam:

it can be a handy material for insulation:

and you can grow it yourself:



Wow @davidwilliamson82 - a pleasure to have you in the forum, and thank you so much for sharing this knowledge! I thing once @Jonathan_Minchin sees this he might just fall in love.

A quick scan of the Ecovative site seems to indicate they don’t yet produce 4x8x3/4" sheets of mycelium, but it also looks like you can contact them and propose new product ideas. Very cool. I’ll make an effort to connect with them, as they seem very aligned.

Awesome! :smiley:


This sounds great @davidwilliamson82 , I’m currently tooling up to get the bio-bricks And other shapes made with mycelium. Though this is to grow them in situ and harvest mushrooms from. I’d also be really keen to explore techniques of pressing colonised substrate into durable custom shapes. I love working with molds and I’m looking forward to exploring this kind of technology more. Very cool stuff! Thanks for sharing it with us!


right. I’m not sure how they are proposing to sell the mycoboard, but it would appear that they have a custom press made for a shape they intend to replicate on an industrial scale. It isn’t really practical to cut chitin, as it tends to chew up metal.

the methods I was taught involved putting inoculated substrate (corn and hemp mulch, essentially) into PETE molds, where the substrate would be slowly (two to three weeks) colonized by the mycelium. Once the mycelium had colonized the mold, it could be baked (>200 F for several hours), in order to sterilize it. Note: baking it isn’t necessary, as the caps are not allergenic or toxic in any way. This is a design decision, based on the application.

After this, the mycelium component would be able to decompose, similarly to the way wooden components are able to decompose, when subjected to sufficiently damp conditions.

Notice, they are selling the 0.7 cu ft bags of inoculated substrate for $19.95, but i believe that they will negotiate with customers who intend to buy in bulk.

I believe that this material might provide an interesting alternative to CNC routed plywood components, assuming you wanted to make the same component several times over. I’m personally interested in using this material as an alternative to cement in the planter wall. If I ever make it a reality, I shall document.



I can see this as a part of insulation for the nesting area of the chicken coop. Been spinning heads thinking about the insulation for the hens, just in case the current iteration of the chicken coop design wouldn’t work. Thanks @davidwilliamson82 !


Hello !
I am actively working with mycelium insulation application for honeybee housing. ! I built the OS BCN Warre Hives to create a stable structure to first test the material. Now looking for ways to make the whole piece together with the assembly joints with mycelium.


So cool!

So the mycelium purpose is for insulation? I wonder if you have heard about the work of Paul Stamets and if there could be other beneficial properties of using this material internally?

Such awesome work!!! :mushroom: :honeybee:


Hello !
Yes, that is the reason by bio-chef here in the lab allowed me to apply this material for the beehive enclosures :slight_smile:
I am now looking into my 2020 experiments where I test the material for therapetic reasons
thanks for OS beehives :dancer:
