Using the FDM technology for prototyping in fields like aerospace and medicine has brought to light the significance of dimensional precision in manufactured models. Layer thickness, raster width, infill pattern, etc. are only few of the many process parameters that might affect the dimensional accuracy of FDM-printed items. In order to understand the individual effect of each process parameter and to determine the optimal levels of each parameter based on the material types, this study aims to conduct a comprehensive literature review of publications that investigated the effect of process parameters on the dimensional accuracy of FDM printed parts. Material types such as ABS, PLA, and others were summarized alongside an evaluation of 29 publications that examined the impact of three process parameters: layer thickness, extrusion temperature, and component orientation. Tables summarized the key findings from each study, revealing the optimum value for each process parameter and describing the articles' respective methods. Layer thickness levels between 0.1 and 0.2 millimetres are recommended for ABS and PLA parts, whereas higher layer thickness values are typically associated with greater precision for ASA and Nylon parts. The extrusion temperature is determined to be optimally low, and this parameter is also less sensitive to variations in the material being used. With regards to part orientation, it has been determined that 0 degrees is best for ABS printed parts while 90Ois best for PLA printed parts. Furthermore, additional factors like the geometry of the part, the type of resin, and the varying dimensions of the part are likely to affect the ideal level of each process parameter. In order to fully grasp the impact of each process parameter on the dimensional accuracy of FDM printed parts, it is necessary to take into account the influence of confounding variables.
