Through this experiment, we are testing the water temperature and amount of water at which thermoplastic material needs to fully transform from 2D to a 3D model for our origami tutorial book. We are testing this aspect to see if this would be safe to create at home and what precautions are needed to make this book safe to use for our target audience of teenagers and adults. It would help us decide if there are extra components we need to include in this experience in the product (i.e. dropper, thermometer, etc).
We plan on creating creases and cuts in PLA filament to see if the material folds fully through the creases with the variation in moisture and heat.
A: Temperature Experiment: 6 qt of water will be used for each Temperature. We will test temperatures from 100F to 212F in increments of 20 degrees and record when heat in the water is enough to cause warping.
B: Volume experiment: This is completed after the temperature experiment. Using the determined Temp from A, we will start with minimum water volume (just enough to cover the shape) and add 2 cups of hot water up to the 6 qt capacity of the pot.
