Comparison of STL models and 3D-printed models with (A) twelve lengths based on landmarks, (B) the Bland–Altman plots present differences in mean between STL and 3D-printed models from the three patients. STL, stereolithography; 3D, three-dimensional (R packages: blandr, ggplot2). (C) The distance maps with color legend show overall discrepency between surfaces of STL and 3D-printed models.
