Abstract
Additive manufacturing is a promising technology which finds varied applications in industry. Fused Deposition modelling technique has improved the range of application of AM as it utilizes layer by layer deposition to manufacture faster prototypes of different dimensions and geometries. Studies have focussed on the mechanical behaviour, especially the tensile strength of printed parts and how it is been influenced by various manufacture and process parameters. This work focusses on studies on the influence of raster patterns and presents a comparative study of mechanical properties other than the commonly inferred tensile strength, namely, flexural, compressive and impact strength of FDM printed PLA parts printed in two most commonly employed raster orientations, +450/-450 and 00/900.
