The purpose of this study is to improve the dimensional accuracy according to the material and size of a given printing object in 3D printing processes using fused deposition modeling (FDM). When printing an object with the selected material, appropriate printing parameters are suggested according to the object size. We experimentally analyze how changes in the material and size of the printing object, and printing parameters such as the extrusion temperature and infill, affect the dimensional error. The experiment was conducted by measuring the dimensional errors in printing specimens of the same shape but various sizes using an FDM-type 3D printer under various printing conditions. Given the material and size of the printing object, it was found experimentally that the dimensional error has the characteristic of a straight line or a parabolic shape according to changes in the extrusion temperature and infill, which are printing parameters. Given the size of the object to be printed, the printing material is appropriately selected by considering the material properties of the required part and the dimensional accuracy of the material obtained through the experiments. It was concluded that printing with appropriate printing parameter values obtained through experiments according to the selected material and size of the printing object can improve the dimensional accuracy of the FDM-type 3D printing process.
