3D PRINTED FUNGUS HOME

"Print a home for your fungus"
 differential growth and bioplastic
In our short project (2 weeks) we had the task to research a biodegradable material which will be used as a sewing ground for a mycelium. The material should be 3D printed in a designed shape with the help of a robotic printer. The project was directed by the Materiability research group.

At the beginning of our project we asked ourselves what does a mushroom need? Which conditions are the best for our fungus? After a short research we found out that the mushrooms not only prefer a dark environment, they also have to be watered or moistened regularly and the humidity should never be below 70%. Therefore we have more focused to creating a bioplastic material that is as waster resistant as possible. Also our printed object should be able to withstand multiple mushroom growth cycles without disintegrating.The water resistant properties of our material can also be used in other areas, for example in outdoor applications, greenhouses, bathrooms or places with a high humidity.

With grasshopper I developed a generative algorithm to be able to simulate a differential growth. Differential growth described the form of growth that can be observed in fungi, many plants and animals. The cells of an organism divide at different rates, that causes it to grow bulky and uneven. Typical are wavy contours and edges that are never straight.
Our 3D printed 1:5 model
3D print with our bioplastic material and the robotic printer. The printer printed our pallets that we made out of chitosan, maize and our basic recipe. 
Final home for our Fungus

Now we have to wait until our mushrooms have grown.
