Volumetric comparison of scans obtained at varied speeds (2, 4, 6, 8, 10, 20, 30, 40 and 50 RPM) at a fixed distance revealed consistency in the quality and relative accuracy of the produced meshes. In general, no measure differed from the mean volume (434.16 ± 19.61 cm3) by more than 6.13%, which occurred only at the highest speed of 50 RPM. This indicates that the apparatus is both repeatable and accurate in its model creation.
