1. Divide students into small groups.
2. Students will go online to https://support.printm3d.com/145216-3D-Models and download the torsion test models.
3. Each group should print one torsion model in at least three different types of materials.
4. Once they have their models printed, students should add weight to one side and measure how much weight it takes to rotate the model 1, 2 & 3mm.
