Parametric Optimization Based on Mechanical Characterization of Fused Deposition Modelling Fabricated Part Using Utility Concept

Fused deposition modelling is a swiftly budding RP technology because of its facility to manufacture serviceable parts with multifaceted geometrical forms in equitable time without the help of any tooling or human interface. The characteristics and functionality of FDM fabricated parts exhibit high dependence on a few processing parameters and their level of settings. The present study determines the relationship between five substantial processing constrictions, i.e. raster angle, layer thickness, air gap, orientation and raster width, and how they affect compressive strength, tensile strength, impact strength and flexural strength of the fabricated part. Twenty-seven experiments have been piloted using Taguchi’s design and optimized using Utility concept. Finally, the confirmation test was done for the validation of the obtained results.
