Fused deposition modeling (FDM) is simplest and cost-effective additive manufacturing (AM) technique, which prints the components by squeeze out the molten material through a nozzle and deposits on a substrate in a controlled manner. The advantage of FDM is to fabricate complex geometry without using the pattern, die and tools. The mechanical properties and build quality of 3D printed parts greatly depend upon process parameters that could be enhanced by selecting optimal parameters. Recently, FDM has been a preferred choice of researchers to develop polymers-based nanocomposites. A good number of research works are carried out to study the influence of FDM process parameters on the performance of printed products. Therefore, there is a great need to review the research works performed on the effect of FDM process parameters. The present review discusses the impact of FDM process parameters on the performance of the products and identifies the vital parameters.
