Fused deposition modelling (FDM) is most commonly used processes in additive manufacturing. FDM uses raw material in the form of wire filament and works on the principle of extrusion. Acrylonitrile butadiene styrene (ABS) is commonly used engineering plastic in FDM process for printing different parts for functional purpose or prototyping. As ABS is less expensive material among other plastic used in FDM process. The availability and cost of ABS highlights its more use in additive manufacturing. Mechanical properties of ABS can be enhanced by copper plating. Copper plating on ABS can provide good tensile strength and impact resistance to the ABS parts. . To optimize the printing parameters using taguchi’s method, Minitab software is used to generate optimum number of combinations for printing of ABS parts. This work describes the detail study on investigating the physical and mechanical properties of ABS part without plated and copper plated ABS parts with different layer thickness 50µm, 200µm, 400µm and 600µm. Tensile strength, impact strength and hardness values for these different parts are found by various experimental tests. Focusing on the end results it was observed that after coating 600 micron layer of copper over 3D printed specimens, tensile strength is increased by 321.67% , whereas Mirco Hardeness by 139% and Impact strength is increased by 190% than existing properties of as printed specimens. It can be concluded that copper coating provides better option for improvement in mechanical properties of 3D printed parts without considerable variation in weight of parts or going for expensive metal printing process.
