Abstract : 3D Printing technology has been extensity used to fabricate engineering components within a short span of time in small scale. The quality of parts being produced using 3D printing depends on the build parameters. This paper presents a study on the mechanical behaviour of 3D printed structures under the influence of build parameters such as build orientation, layer height, fill density, extrusion temperature and printing speed. Preliminary studies on the influence of build orientation were carried out by varying the y-axis orientation of the specimen and confirm that model built using y –axis orientation of 45° yields better mechanical properties. The specimens were built using Poly Lactic Acid (PLA) material with different combination of the process parameters based on Taguchi’s approach. The influence of the above parameters on the tensile strength, Young’s modulus and printing time were analyzed and optimized. © International Journal of Modern Manufacturing Technologies.
