Abstract
Additive manufacturing offers flexibility in designing, customizing, minimization of waste, manufacturing complex profiles and faster prototyping. Among these, polyjet and fused deposition modelling (FDM) process are widely employed to manufacture the parts for different applications. Hence, a comprehensive review on the mechanical properties of polyjet printed and FDM printed parts has been carried out in this paper. Under polyjet printing, influence of process parameters such as built orientation, built mode, finish type, part spacing and layer thickness on the mechanical properties has been discussed. Under FDM process, mechanical properties of important and potential polymeric materials such as acrylonitrile butadiene styrene, polylactic acid, polyether-ether-ketone and polyetherimide have been reviewed. Altogether, this paper gives an overview of mechanical properties of 3D printed parts, including a survey on selection of process parameters in polyjet process and materials selection in FDM process.
