Influence of the Printing Orientation on Parallelism, Distance, and Wall Thickness of Adjacent Cylinders of 3D-Printed Surgical Guides

This in-vitro study aimed to evaluate the influence of printing orientation on parallelism, distance, and thickness between adjacent cylinders 3D-printed surgical guides. CAD software was used design a guide with two parallel (reference); saved as standard tessellation (STL) 63 samples were printed using three different orientations (0, 45, 90 degrees). A metrology digital microscope measure angle guides cylinders. Afterwards, scanned cloud comparison compare STL files from against reference model. One-way analysis variance Tukey test for multiple comparisons groups significance p < 0.05. The affected distance cylinders, parallelism wall thickness. In addition, there global deviations in all orientations. Printing degrees produced almost-parallel but walls thicker than model; converged toward coronal at 0 closest value. Within limitations this experimental it can be concluded that angle, guide. produces best correspondence master
