6 Biofabricating materials

Learning outcomes

--> Produce at least two grown and/or two crafted materials:
+ Grown materials - Grow a material, experimenting with at least 2 different recipes and variations thereof. Document the process, ingredients, changes, describe and compare the materials
+ Craft materials - Craft a material, experimenting with at least 2 different recipes and variations thereof. Document the process, ingredients, changes, describe and compare the materials

--> Document your recipes, the ingredients and process and if there have been changes, document your unexpected discoveries

--> Name your materials, classify them by typology and display them in a systematic order of samples. EXTRA POINT Submit some of your swatches to the analog material library of your lab. (20cm *20cm aprox)

Inspo

--> Material Driven talk


--> Smile Plastics


--> Ottan studio making materials with foodwaste


--> Inspired by the following work on plastic, recycling it or biofabricating it

Lecture takeaways

--> We overviewed different techniques to make bioplastics and bioleathers, from different materials, amongst them:
+ Bioplastics can be made out of: alginate, gelatine, algar
+ Bioleathers can be made out of: kombucha, mycelium, fishskin



--> Documenting is key when it comes to biofabricating materials



--> Felt very inspired by the Remix El Barrio project, where participants get to learn how to value their own food waste, and recycle them from home.

Grown materials

Mycelium leathers

--> I followed the following mycelium leather recipe


--> Tried 3 different states of mycelium: with liquid mycelium, with the brown part of solid mycelium, with the white part of solid mycelium


--> results solid white mycelium


--> results liquid syringe mycelium


--> results solid brown mycelium


Mycelium + coffee + pine

--> I tried a random recipe mixing the following ingredients: coffee waste, pines, mycelium, liquid nutrient. I'm letting it rest at a temperature of 28C.


--> results lots of pines + coffee + mycelium


--> results coffee + mycelium + tiny bits of pines


Crafted materials

Alginate bioplastic

—-> I followed the alginate recipe. I did not let the alginate texture rest so there's bubbles in it. I added turmeric to dye the plastic (turmeric pigment made on week 4), and used both salt table and ice melter as substitute for calcium chloride.

—-> Final texture is not strong, really feels like gummy bear:

--> Results after 1 week rest, it dried!

Gelatine bioplastic

--> I followed the gelatine recipe:
--> Results: it did not dry at all it stayed like a honey texture. What possibly went wrong, is that I was using Jello? Or I added too much glycerin.
--> I tried recooking it, but texture did not change, only the color, probably because it burned, this is after one week of rest:
