Material Flexibility and Weight Test

thingiverse

For a school science project, I decided to experiment with various 3D printing plastics, so I created these test pieces. Cut them into multiple sections for different types of plastics. I used PLA, ABS, and PETG. To conduct the flex test, simply clamp the test piece to a table and add weight. For the weight test, hang the test from a secure location and add weight. I will be adding my final research paper and pictures as they become available. Thanks! Edit: 1/19/17: I realized that the weight test was too thick to snap under any realistic test weight, so I redesigned it to be significantly thinner. Completed tests will be added with graphs soon. Print Settings Printer: Anet A8 Rafts: Don't worry about this setting. Supports: You can ignore this option as well. Resolution: Low-quality resolution is sufficient for this project, set at 0.15-0.2. Infill: I used a 15% infill for the flex test and 100% in the weight test. Notes: For the weight test, use support material. Designed using Autodesk 123D. Post-Printing To prepare the tests, simply peel off any support material and follow the instructions above.
