Abstract
Additive manufacturing is a rapidly growing cutting edge technology. Number of experimental studies have shown that strength of product manufactured by additive Fused Deposition Method (FDM) is influenced by different processing parameters involved during manufacturing. This thesis work presents experimental and theoretical investigation of mechanical behavior of ABS material fabricated with variation in some of process parameters such as Axis Orientations, Raster Orientation, Infill Percentage, Layer Height and Number of Shells. Different experiments were designed to understand the basics of 3D printing manufacturing and to characterize the mechanical behavior of 3D printed structures. This study helps to understand, how different raster orientations affects the fracture toughness of 3D printed structures and also tell us under which process parameters additive manufactured structures provide better tensile, shear and compressive strength. Using this study we can understand and develop optimized manufacturing process for robust 3D printing manufacturing.
