7. BioFabricating Materials¶
Since this week, I’ve come to Fablab Barcelona to participate in Fabricademy. Last summer, I joined Feature Fabrics Mexico, which sparked my interest in textiles! Working with people who share similar interests, and from different countries, for a common goal was both exciting and a valuable experience. When I decided to enroll in Fabricademy, I consulted with Anastasia, who helped arrange it for me.
Usually, I work at my Fablab in Japan, with Nuria, my remote instructor from Leon. However, for these three weeks, I’ll be working directly under Petra in Barcelona, alongside everyone else attending here—That sounds awsome!
Research¶
For the project, I'm doing some research. At Beyond Fashion in Mexico, I saw clothing made from grape-skin leather. There are so many types of bio-leather emerging now, like cactus leather and apple-skin leather... I even already have a wallet made from pineapple leather that I love. I’ve also come across works made from soy leather by an art collective in Indonesia, and in Japan, leather made from discarded tea leaves. I can really feel how rapidly the development of biomaterials is progressing!
I once applied a method using alginate in cooking. I put beaten egg yolk into an alginate solution and then dropped it into water with dissolved calcium chloride using a syringe. I can’t wait to make biofabric using the same method! It’s so exciting.

Crafterd Material¶
-1. Sodium Alginate - Bio yarm & Bio plastic
"ingredients"
A * Sodium Alginate 8gr * Water 400ml * Glyceline 60gr * mica
B * Calcium chloride 60gr * Water 600ml
"recipe"
A
* Put water on the pot
* Add the sodium alginate and mix with water.
* Add the glyceline into the pod and mix well.
* With pink mica, make it pink.
B * Put water on the pot * Add the calcium chloride and mix well.
When A and B are prepared... * Draw A into the syrinder. * Add the glyceline into the pod and mix well.
- Avoid touching the tip of the cylinder.
- First, add A little by little into the pod containing B.
- Then, continuously press the cylinder to fully dispense A.
- The A that was poured into B will solidify. When scooped by hand, it forms a thread-like shape. Let it dry.=Bio yarm.
- Pour half of A onto a fabric stretched in an embroidery hoop to create a mold, let it harden=bioplastic.
-2. Gelatine-Bio foam & Bio plastic
"ingredients"
* Gelatine 48gr
* Water 240ml
* Glyceline 48gr
* soap
* Spirulina powder
"recipe" * Heat the pot. * Add water to the pot, then add gelatin and heat it while stirring until the gelatin is dissolved. * Add the spirulina powder to make it green. * Pour half of it directly into the mold. =Bio plastic * Add a small amount of detergent to the remaining half, then mix it further with an immersion blender. * After that, pour it into the mold.=Bio foam * Once both have cooled, they are ready!
-3.Agar-Agar Bio foil
{ width=650 align=right }
"ingredients" * Agar-Agar 20gr * Water 600ml * Glyceline 32gr * mica
"recipe"
- Put water on the pod
- Heat the pot.
- Add the agar-agar and melt it.
- Add glyceline into the pod and mix well untill it melts.
- Pour the mica into red!
- Then, pour it into the mold and wait for it to cool.
-4.Pine Resine- Bio resin
"ingredientes" * Pine Resin 45gr * Canmauba wax 5g * Alchohol 20ml * Fillen 40gr
"recipe" * Line the mold with baking paper and wrap it around the inside of the lid as well. * Heat the pot. * Place the pot over heat and melt the pine resin. * Once the pine resin has melted, add canmauba wax and alchohol and melt them. * Add rhe fillen. * Quickly pour it into the mold, cover it with the lid, and press down from the top.
Grown Material¶
■KOMBUCHA
"ingrientes"
Beer
* Beer 5L
* Water 5L
* Sugar
* Vinegar
Wine
* Wine
* Sugar
* Vinegar
Tea
* Tea bags
* Water 2L
* Sugar
* Vinegar
"recipe"
Beer * Pour beer and water into a large container in a 1:1 ratio. * Add sugar. * Add vinegar. * Check the pH level.
Wine * Pour wine. * Add sugar and vinegar and mix them. * Check the pH level.
Tea * Steep a tea bag in hot water to make tea. * Add sugar and vinegar and mix them. * Check the pH level.
- Put the Kombucha into each container.
- Cover it with a cloth and tie it around the sides of the container with a string to keep out debris.
- Place it in a dark location..
■MICELIUM
To use the Mycelium, we have to do for preparation-sterilise!!
Then we did the 2 ways.
Recipe 1 -MOLD ""
Recipe 2 -PLASTIC TRAY ""
*How to pour into the plastic tray.
3D bio-printing¶
We tried both recipes from Petra's tutorial. - Petra's Tutorial
Recipe 1 ""
-Press the back side of the cylinder against the material, then twist the cylinder to gradually feed the material into it.
-Once it's in the cylinder, blow it clean and securely close the lid.
Recipe 2 ""
How to do 3D printing
-For 3D bio-printing, it`s necessary to hack the 3D printer. Here is also the video how to hack!
-Connect to the compressor in the correct order, including how to open the valve.
Additional work¶
Building on what I did with Petra, I did some crafted material making at home over the weekend with my classmate, Germa

"1-1"
I also tried using alginate for another experiment. I used an egg carton as a mold to create two hemispheres. Once they dried, I attempted to attach the two pieces to form a sphere.
"1-2"
In a slightly deep bowl, pour the alginate solution and add dried flowers, arranging them in the bowl to create a slight indentation. Pour the calcium chloride solution into this indentation, ensuring it evenly covers the surface.
"1-3"
I changed the natural color to red. Since the red natural color was in liquid form, I mixed it with water to reach the required quantity.
"1-4"
I made a patterned piece using rice noodles.
"1-5"
With natural ink that we did on the week04, colored the soldium alginate and made the pink/red strings.
Created a piece with Germa using rice flour noodles.
