Abstract: Fused Deposition Modeling (FDM) is one of the best 3-D printing techniques, where specimen is built as layer by layer deposition from the extruded filaments of melted thermoplastic. Layer orientation plays an important role in surface finish, dimensionality and mechanical behavior. Present work is an attempt to determine the tensile strength, Young’s modulus and fracture strain of the 3-D printed model built by using raster fill method according to ASTM D638 standards. The tensile strength and modulus were shown to vary based on the build orientation of identical test specimen. Fractured surface of the surface shows the 3D printed material behaves more like composite structures. Strain gauges were used to measure the uniform strain during the tensile testing. Numerical Modeling of the tensile set up was done in ABAQUS to replicate experimental results
