Summary

Here I will describe my experiences with the creating a laser cut mould and cooking some biomaterials.

What You'll Need

Kitchenware: pot, stove, stirrer, scales, mixing bowls, measuring jar.

Ingredients: vinegar, glycerin, gelatin, corn starch, used coffee grinds.

Tools: laser cutter, 2D design software

Materials: 3mm acrylic sheet

 

 

The Instructions

Drawing the design for the mould.

Autocad was used to design a 3D object (a reindeer) made from 2D parts.

Using an online image as reference, I drew the 4 pieces that make the reindeer: body, 2 sets of legs, antlers and ears. I used Autocad to do this. I exported a .dxf file.

Cut the design

Laser cut the design

Using a laser cutter I cut my design. The cut out pieces will be my 3D object for the coming assignment, the remains, my mould. I cut it in 2 different sizes. My goal is to obtain replicas of the 2 reindeer made from biomaterials.

 

Cook the materials

Follow the recipes to cook some biomaterials.

I tried 2 different recipes to cook 2 biomaterials. One of the recipes is in the images.
