Recently, dentists can utilize three\u2010dimensional printing technology in fabricating dental restoration. However, to date, there is a lack of evidence regarding the effect of printing layer thicknesses and postprinting on the mechanical properties of the 3D\u2010printed temporary restorations with the additive manufacturing technique. So, this study evaluated the mechanical properties of a 3D\u2010printed dental resin material with different printing layer thicknesses and postprinting methods.\n                    <jats:italic>Methods<\/jats:italic>\n                    . 210 specimens of a temporary crown material (A2 EVERES TEMPORARY, SISMA, Italy) were 3D\u2010printed with different printing layer thicknesses (25, 50, and 100\u2009\n                    <jats:italic>\u03bc<\/jats:italic>\n                    m). Then, specimens were 3D\u2010printed using DLP technology (EVERES ZERO, DLP 3D printer, SISMA, Italy) which received seven different treatment conditions after printing: water storage for 24\u2009h or 1 month, light curing or heat curing for 5 or 15 minutes, and control. Flexural properties were evaluated using a three\u2010point bending test on a universal testing machine (ISO standard 4049). The Vickers hardness test was used to evaluate the microhardness of the material system. The degree of conversion was measured using an FT\u2010IR ATR spectrophotometer. Statistical analysis was performed using two\u2010way analysis of variance (ANOVA) and Tukey\u2019s honestly significant difference (HSD) test (\n                    <jats:italic>p<\/jats:italic>\n                    \u2264 0.05).\n                    <jats:italic>Results<\/jats:italic>\n                    . The 100\u2009\n                    <jats:italic>\u03bc<\/jats:italic>\n                    m printing layer thickness had the highest flexural strength among the other thickness groups. As a combined effect printing thickness and postprinting conditions, the 100\u2009\n                    <jats:italic>\u03bc<\/jats:italic>\n                    m with the dry storage group has the highest flexural strength among the tested groups (94.60\u2009MPa). Thus, the group with 100\u2009\n                    <jats:italic>\u03bc<\/jats:italic>\n                    m thickness that was heat cured for 5 minutes (HC 5\u2009min 100\u2009\n                    <jats:italic>\u03bc<\/jats:italic>\n                    m) has the highest VHN value (VHN = 17.95). Also, the highest mean DC% was reported by 50\u2009\n                    <jats:italic>\u03bc<\/jats:italic>\n                    m layer thickness (42.84%).\n                    <jats:italic>Conclusions<\/jats:italic>\n                    .
