The Effect Of Print Angulation On The Accuracy And Precision Of 3d-Printed Orthodontic Retainers, Allison Williams
Theses and Dissertations
Purpose: The aims of this study were: 1) to compare the accuracy and precision of 3-
dimensional (3D) printed retainers at various angulations, 2) to evaluate the effect of angulation
on printing time and the amount of resin consumed.
Methods: Using a stereolithography (SLA) 3D printer, a total of 60 clear retainers were printed at five angulations (n=12, each): 15, 30, 45, 60, and 90 degrees. Six retainers were printed each cycle at a random order for all print angulations as print 1 and print 2. Digital images of the original and printed retainers were superimposed. Discrepancies on eight landmarks …
