The aim of this study was to evaluate the impact of the 3D printing process itself and subsequent steam autoclaving on the dimensional stability of five different resin\/printer combinations (RPCs).<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>Fifty identical surgical guides (10 per group) were produced consisting of five RPCs. Half of the guides (5 per group) were steam autoclaved with cycle 1 (121\u00b0C, 1\u2009bar, 20.5\u2009min) and the other half with cycle 2 (134\u00b0C, 2\u2009bar, 5.5\u2009min). All guides were scanned with a structured\u2010light (SL) 3D scanner before (T0) and after (T1) autoclaving. Linear measurements along the x\u2010, y\u2010, and z\u2010axes were performed at landmarks on the original STL file and on SL scans at T0 and T1, respectively. Wilcoxon signed\u2010rank test, Kruskal\u2013Wallis test, and linear mixed\u2010effects models were performed, depending on the analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Three\u2010dimensional printing was associated with significant dimensional alterations for all RPCs. Steam autoclaving using cycle 1 was associated with significant shrinkage in x\u2010 (1 RPC), y\u2010 (2 RPCs), and z\u2010direction (2 RPCs), while cycle 2 was also associated with shrinkage in x\u2010 (2 RPCs), y\u2010 (1 RPC), and z\u2010direction (1 RPC). One resin did not present any dimensional changes independently of the cycle.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The majority of the guides presented minor but significant shrinkage due to 3D printing itself and both steam autoclaving cycles, the extent varied between different RPCs.
