MakerBot PLA Material

Project Preference

 * MakerBot PLA Material
 * Bernoulli effect
 * Corn starch

Problem Statement
The modulus of elasticity and deflection of 3-D printed objects will be tested using the 2- and 3-point bending test

Project Plan
The plan for the next 4 weeks is to:
 * Brainstorm ideas for objects to test
 * Cylinder
 * Rectanulaar Prism
 * Triangular Prism
 * Print the models
 * Vary testing parameters including:
 * Infill
 * Color
 * Perform 2-point bending test
 * Perform 3-point bending test

Week1 Narrative
Different shapes to test using 2- and 3-point bending configurations were researched/brainstormed.


 * Ideas for objects to test:
 * 1) Cylinder
 * 2) Rectangular Prism
 * 3) Triangular Prism
 * 4) Pentagonal Prism
 * 5) Ruler Like

Week2 Narrative
CAD files for the different test geometries were created and converted to be in the same language as that recognized by the 3-D printer.


 * CAD Files for the objects that will be tested are as follows:
 * 1) Cylinder https://commons.wikimedia.org/wiki/File:I_beam.pdf
 * 2) Rectangular Prism https://commons.wikimedia.org/wiki/File:Rectangular_prism.pdf
 * 3) Triangular Prism https://commons.wikimedia.org/wiki/File:Cylinder_9-25-14.pdf
 * 4) I-Beam https://commons.wikimedia.org/wiki/File:Triangular_prism_9-25-14.pdf

Week3 Narrative
Inventor files were converted into STL files in order to print/get certified. One object was printed, the image of which is below.
