The created ball STL model expanded in the X-, Y-, and Z-axis directions, with the length in the Z-axis direction (body axis direction) being slightly longer than that in the other directions. Results: The data (file) size of the STL file and the number of triangles that constitute each STL model were different across all software packages, but no statistically significant differences were found across software packages. Additionally, to evaluate differences between the shapes of the STL models by software package, each pair of STL models was superimposed, with the observed differences between their shapes characterized as the shape error. Once the STL models were created, the data (file) properties and the size and volume of each file were measured, and differences across the software packages were noted. The DICOM image file was then segmented and exported to an STL file using nine different commercial/open-source software packages. Multidetector row CT scanning was performed on a dry human mandible with two 10-mm-diameter bearing balls as a phantom.
