Dimensional Precision of Abs Parts Manufactured By Additive Manufacturing in FDM Technology

- This article presents a study carried out with 24 parts printed using 3D FDM printer. The main objective of the research was to contribute to the optimization of printed parts in additive manufacturing by fused deposition modeling (FDM). To make this possible, the DoE methodology was used together with the Taguchi’s method. This study confirmed that the three-dimensional printing FDM parameters influence the dimensional accuracy of the parts. When using FDM additive manufacturing, it is recommended to analyze the position in which the part will be printed, to guarantee it dimensional accuracy. Also, it is important to check the layer height and print speed of the fill, which reflects on the print time, to ensure the part has high dimensional accuracy.
