This project studied variation of material properties, particularly the Young’s modulus, under different 3D prints orientation using three different approaches. Experimentally, we created a testing apparatus that would hold cantilever beam test specimens. For numerical analysis, we remade the model with the printing pattern in Solidworks and used finite element analysis to compare experimental results to the theoretical results. We also researched microstructures for justification of variance in 3D prints due to certain print settings. The results have shown that mechanical properties of 3D prints varies with the manufacturing setting, for example, print orientation has an effect on the Young’s modulus of 3D prints under print orientation.
