Modifying the interior structure of the artifacts improves not only the strength of the parts but also the dynamic responses of them which can be tuned according to the resonance frequencies of the mounting platforms. Additive Manufacturing (AM) approaches are the finest solutions for the fabrications of these parts with structured interiors. In this study, the main aim is to analyse the effect of improved lattice structures on the natural frequencies of the parts optimized for compliance. The effects of compliance optimization on the fundamental natural frequency are presented to understand the necessity of using multi-objective optimization to extend the life of the products under the vibration. A pipeline from the design of the parts to the fabrication of them with improved mechanical properties is achieved. The process is automated using MATLAB and parametric module of NX 10. Fabricated parts are mechanically tested and the modal analyses are performed using ANSYS to compare the effectiveness of the approach on the natural frequency.
