7. BioFabricating Materials¶
Welcome back! This week is all about exploring biomaterials, composite materials, and kombucha.
It is about seeing the potential of these materials and how they can be used across different fields. This week has been really fun and full of exploration and things I never thought about before!
Introduction¶
Short long story the bio material all about : waste becomes wealth
Bio material sector today in evolution as in evolution as part of bio-based and circular economy. In this emerging economic model, biological resources, agricultural residues, and organic waste streams become valuable inputs for material production.
SO instead of deal with them as a waste material we can reuse them and create new material or composite material from. aiming to minimize pollution and regenerate natural systems.
References & Inspiration¶
I found many interesting bussiness and material experts in this feild and some of the inspiration i found could go to these videos below .
Process and workflow¶
The cooking process for bio-material¶
These are the steps for prepare to cook bio materials and this method is applied to all of next diffrent materials. Here good resource to explore some of bio material at your own place check here
Gelatine Bioplastic¶
Gelatin's is a biopolymer we get by heating up collagen from animal skins and bones, with a bit of dilute acid to help break it down.
Gelatine-Bioplastic Recipe¶
| POLYMER | PLASTICIZER | SOLVENT | ADDITIVE | Notes |
|---|---|---|---|---|
| GELATINE 48g | GLYCERINE 12g | WATER 240g | Coffee Ground 3g( or more) | It can be semi flexible when it n not 100% dry and hard when it is fully dry |
Feel free to check this website for more recipies for bioplastic gelatine
Agar-Agar¶
Agar is a compound known as polysacharide, extracted from red algae.
It is considered the best vegan alternative to an animal-based gelling agent like gelatine. Agar agar – is the Malay name for the red seaweed from which the powder is extracted.
Among the others, agar is colourless, odourless and tasteless and preserves waterproof properties.
It is indeed insoluble in cold water.
As shown in the photo : made this as any other material you can see the recipe in schedule below and using food color as an optional step if you want color . after the material get ready it is important to prevent leave it and pour it directly before it became cold. And here i pour it on a straight surface from the middle point as material will spread by its self . however i think it is good for test but if you want a well balanced material thickness then pour the material inside a mold.
Agar-agar Recipe¶
| POLYMER | PLASTICIZER | SOLVENT | ADDITIVE | Notes |
|---|---|---|---|---|
| AGAR AGAR 5g | GLYCERINE 15g | WATER 250g | FOOD COLOURING 1g | Flexible material |
Alginate¶
Alginate is made by combining sodium alginate, water, glycerine and a curing agent: Calcium chloride.
Calcium has the ability to form 2 bonds which will hold the alginate into a polymer.
It made as above steps but unlike agar agar here i used a silicone mold to pour a thin layer of alginate and leave it until dry.
Alginate Recipe¶
| POLYMER | PLASTICIZER | SOLVENT | ADDITIVE | Notes |
|---|---|---|---|---|
| Alginate 12g | GLYCERINE 20g | WATER 200g | sodium chloride hydrate 10ml | optional to add 10ml of sunflower to have flexible bio-plastic |
Kombucha¶
Kombucha is produced by fermenting sugared tea using a Symbiotic Culture of Bacteria & Yeast SCOBY commonly called a "mother" or "mushroom".
Kampucha workflow
How to prepare Kampucha?
1. 1. Brew the tea. .
2.2. Add sugar, filter the solution.
3. Add a splash of vinegar to make the solution acidic
4. Check the PH and keep adding vinegar until it reaches PH 3/4.
5. Use gloves and disinfect your hands.
6. Add your SCOBY mother being sure it floats on the liquid.
Needs to wait for this mother kampucha to grown in the tea water made previously -following the ingresient above "grow fabric in kichen" it could need 3 weeks or a month to be fully grown and ready to be used . it will be used in scaffoled week
Bio Material Comparision¶
| Gelatine Bioplastic | Agar-Agar | Alginate | Kompucha |

| It can be semi flexible when it n not 100% dry and hard when it is fully dry | Flexible material,strong with good potental | optional to add 10ml of sunflower to have flexible bio-plastic | good diffrent material bacteria based and can be smelly |
Laser Cut - Biomaterial¶
I searched for a photo related to rumi to try it with cut on the bio material (Gelatine Bioplastic) to be drawn on with low power in laser settings.
Laser - Result¶
Laser video¶
As you can see the laser been working excellent ! even though laser can be working more towards some jewellery design from bio or more artwork - been new experience to me laser cut bio material but the results are well promising!
