Biomaterials can be created from what you already have at home, or with ingredients readily available at the grocery store.
In this lesson, we will creating a laser cut mold. We will be using 2 recipes to cook the bio materials.
1) Agar agar
4) Food coloring
6) Weighing scale
7) Measuring cups
9) Induction cooker
A laser cutter will be used to cut our acrylic mold. Using food ingredients, we will be making our own biomaterial.
1) I used Coreldraw to design my laser cut file.
2) I stacked the acrylics to create the mold. I created the 4 holes to help me to align them accurately and tightened together with screws and nuts so that there is no gaps when I apply the acrylic glue to them.
Agar Bioplastic is made by mixing water, glycerine and agar-agar powder. They form a plastic substitute that can be cast in very thin films, resembling plastic foils. The casted material is never elastic but is flexible.
We are using the following recipe:-
measuring the ingredient
Mix the water, agar and glycerol together in a pot. Stir until the agar and glycerol have dissolved. Cook over medium heat and stir until the solution starts to boil and becomes viscous.
Pouring into molds.
