The project's goal is to investigate different infill types' effect on 3D printed parts' strength.  Reducing infill percentage will significantly lower printing times as well as weight and material costs but what about strength and stress. Different infills may serve different purposes, there are many literature on the topic. 

A 30mm3 cube with full infill is the reference and different infill types with 50 and 25 percent infill ratio are compared with it. 

Static analysis is to be made. 1N tensile load is to be applied on the top plane while the other plane is fixed. Maximal stress and deflection values are to be checked.

Please note that as 3D printed parts are build of layers, the anisotropic behavior has significant impact on parts' performance as well as different parameters like printing material, temperature, perimeter shell number, just to name a few.
