Optimized Environment Parameters from Dimensional Accuracy for FDM-type 3D Printing System

3D printing of the fused deposition modeling (FDM) type is the most common, and has a large number of users. FDM-type 3D printing has many advantages; however it has some problems and disadvantages too. If these disadvantages are overcome, the utilization of FDM type will be maximized. In this paper, some parameters are identified to adjust for improving the quality of FDM type 3D printing, research the correlation between the proposed control parameters, and suggest the optimization methodology with the identified parameters. We confirmed that various parameters involved in FDM-type 3D printing. There are already a lot of information about these parameters, but we tested them scientifically and verified. Particularly, when verifying the relation between parameters and 3D printing quality, the characteristic according to the bed temperature has negative influence of the overall quality as the 3D printing progresses. The bed temperature characteristics were found to contribute to 3D printing quality that the bed temperature be adjusted by lowering or eliminating is better than the bed temperature at the material set well on the bed. Currently, almost all FDM-type 3D printers require manual adjustment of parameters, and the study of these parameters would be a milestone in the development of the automation technology.
