Objective: In our study, the effect of changing the lower threshold and layer height on the model size from the parameters used in the production of 3D (three-dimensional) mandible model obtained from computed tomography images was investigated. Method: We used maxillofacial CT images of a 35-year-old healthy patient in the segmentation and printing process of 3D mandible model. In the segmentation process, the threshold value was used 200,175 and 150 Hounsfield units (HU), printing layer height was 0.1, 0.2, and 0.3 mm in the printing of the created models of polylactic acid (PLA) filament material. The obtained models were scanned with a high precision scanner. Their data in STL format were transferred to the computer, then scanned models were compared with the reference model, and the difference between them was determined. The Taguchi L9 orthogonal index was used as the experimental design. In the Taguchi method, the smallest best signal to noise ratio equation was used for the difference with the reference model Conclusion: As a result of the experiments, it was observed that the threshold value had the most effect on the difference between the two factors. Also, it was observed that in the comparison of the mandible models obtained with a 3D printer and the anatomical model obtained from CT, the models were similar.
