Use a laser cuter to create a mold with acrylic
Acrylic Sheet (3mm clear used here)
Cutting software (Lightburn used here)
Basic image of your choice
Use Inkscape to convert a simple rastor image into a vector
Import an image of your choice
Select Path > Trace Bitmap
Right click image > Fill & Stroke > Stroke Paint > select fill & make sure color is set (in this case I set the stroke color to black
Select Stroke Style and set width to 1 px
Save svg file
Prepare vector image for cutting
Import SVG into your cutting program (Lightburn in this case)
Select the appropriate speed and strength (100% and 5 mm/s for this machine)
Load material & perform cut
Load the material into laser cutter
Select the appropriate settings for your laser cutting device
Remove finished product
Note: I experimented with cutting an outline as an alternative mold, but that is not a requirement.
Following the recipe, create a (hopefully) jiggly biomaterial
Agar Agar Recipe:
150 ml of water / 16 g of agar agar / 8 ml of glycerin / dash of tumeric for color.
We were aiming for a springy mixture. Adding less agar agar will be fine and will result in a more stiff final product.
Instructions: Add the water and agar agar in cold to the pot. Heat the mix to a medium temperature while stiring slowly.
Add the glycerin and tumeric. Allow the mix to simmer and pour into the mould once it has begun to harden.
