7. BioFabricating Materials

Research

Biomaterials are the old/ new way to create materials and implement them in this time of climet ciris . Society has become a big consumerist and we need to intirgrate solutions that will have a better effect on the planet. For this we have to see nature and history because our ancestors used the rosusces around them and integrated it to there daily lives why cant we follow in the same foot steps.

We can do this in was of Bio Leathers, Bio Plastics, Bio Gels, Yarn and Fabrics that cen be taken from extracts of natural ememelts from fruit, vegetables, animal waste even human waste of hari and nails we can even use blood.

Polymers

Gelatin, Chint, Alginate, Cellulose

Inorganic matter

Solvent, Pigments, Minerals, Clay/ Spoils

Agar Bio Plastic

A jelly-like substance from red algae is a compound known as a polysaccharide. Made by mixing water glycerine and agar-agar powder. Material that can be used to cast is not elastic but flexible.

• Water Resistant: Bioplastic can dissolve after a couple of hours submerged in water. When submerged in hot water above 60 degrees, it dissolves faster.
• Heat resistant: after 85 degrees, it starts to melt

Sodium Alginate

It is a salt form of alginic acid extracted from the cell walls of brown algae.

By combining sodium alginate + water and glycerine as a base, calcium chloride.

• Water Distinct: Will start to dissolve in
• Heat withstanding: 150c without melting tempters

• TIP if you add in cinimon to any mix can act to help as an natrual anti microbial.

This weeek Task was to create

1 grown material

1 crafted material Along with the recipes, techniques, and characteristics

We consturted the bio yarn,gelatin and a plastic are the option to create.

References & Inspiration

First inspration that came to mind was Catus Leather created by Adrián López Velarde from Mexico. Also looking into the work of Paula Cermeño León that I am intrested into devloping a bio medical amaterial or ptaches like the ones that she has come up with and I think can look into some more potential work in this area that can be healing and anti bactiral.

Overview material research outcomes

Worked with Agaragar,Sodium Alginate,
example from the documentation of Loes Bogers TextileLab Amsterdam 2019-20

Tools

• Agar Agar
• Glycerine
• Alchohol
• Canauba wax
• Colofonia
• Cloruro Calcio
• Calcium Chloride
• Sodium Alginate
• Fillen (orgnic material that you might add)

Heat-safe glass, Spoon, Bowl, Alcohol, Gloves, and a Pot to heat water if the recipe calls for it.

Optional for other projects: add in essential oils as well as syringes to create yarns.

Process and workflow

For 3D priting a bio material

Ingredients & Recipes

Gelatin

* The gelatin needs to heat up but not to boiling point. Depending on how rigged you would like the material to be add more glycerol if you add too little it might also crack there room to experiment and play here * For the gelatin foam just by adding in the soap and mixing it with a hand blender or any type of blender you have to help foam up and create the mixture.

Sodium Alginate

* Strings/ Yarn For this, you will need the first step of Water + Sodium + Glycerol and the second step of Calcium chloride + water in a separate container.

You take the first mixture, along with whatever natural colorant you added to it, and fill a storage container, then dump the syringe into the second mixture of water.

For the second recipe is just to add in all the ingrdients to the mixture and adding it to what ever mold you would like to cast. * for all these recipes are done with cold water no need to heat up.

Mycelium + Agar Agar

• Agar Agar Heat up the water add in mixutre and poor into a mold let it sit in the frige or in a low sunlight. Low humidity place.
• Mycelium For the mycelium, ensure that all the tools and areas you are working in are sterilized with alcohol. Wear gloves and a face mask. Pressure cook the hay and other tools you will use into a bag and sterilize. Afterward, take a straw and other filler that you sterilized. You can grab a piece of it from the mycelium grow kit and integrate it within the mix carefully with gloves, making sure they are sterilized with alcohol. Afterward, put it into a mold of your liking and keep it in a cooler, dark place with little to no sunlight.

For this process, you must have the right mixture of dough-like consistency and lower stickiness to add to the funnel, which is rigged with a cold extruder and uses air pressure to push the material into the 3D-hacked printer. Always load the material layer by layer on something flat and slowly move it into the container. Afterwards, check if the pressuriser will work with the mixture.

Beer Kambucha

* Beer 300ml * Water 300 ml * Sugar 60gr * Vinigar 60gr

Sanitize the container that you will use with alcohol. Add the beer, then dissolve the sugar, and check that the pH is between 4 and 6. Afterward, cover it with a cloth and leave it in a space with low light and humidity. Check the brew once a week to ensure there's no contamination.
