“…Moreover, during the construction of 3D-printed objects, the laser tends to over-cures the layers, leading to dimensional and positional errors in the z-direction as the layers bond to each other [ 33 ]. The more layers involved in the printed object, the greater the probability of potential errors [ 34 , 35 ]. Another possible factor contributing to this effect may be surface roughness.…”

“…Specifically, Group P, featuring a cross-arch support plate, demonstrated superior stability compared to Group U, where deviations were noted in model contraction on both lingual sides in the posterior region. 25 Song et al 26 showed that 90° orientation yielded the best accuracy when compared to 0° and 15°. Hussein et al 27 concluded that build orientation had an influence on the accuracy of the 3D printed partial denture frameworks, especially at a 135-degree angle of maxillary design and 150-degree of mandibular design.…”

Key Clinical MessageThis research investigates the trueness and precision of 3D printing technology in dental applications, specifically focusing on dimensional variations observed in models printed at different angles. The methodology involved importing a dental model into slicing software, adjusting its orientation, and implementing support structures for stability. Subsequently, the model underwent 3D printing five times for each orientation using appropriate equipment and underwent post‐processing steps, including cleaning, washing, and UV‐light post‐curing. The printed models were then scanned using a specialized desktop scanner for further analysis. Accuracy assessment was carried out using dedicated software, employing an algorithm for precise alignment by comparing the scanned files. Color deviation maps were utilized to visually represent variations, aiming to evaluate how positioning during printing influences the trueness and precision of 3D‐printed dental models. Trueness and precision analyses involved the Shapiro–Wilk test for normality and a one‐way ANOVA to compare means of three independent groups, with statistical analyses conducted using IBM SPSS Statistics software. The color maps derived from 3D comparisons revealed positive and negative deviations, represented by distinct colors. Comparative results indicated that models positioned at 0° exhibited the least dimensional deviation, whereas those at 90° showed the highest. Regarding precision, models printed at 0° demonstrated the highest reproducibility, while those at 15° exhibited the lowest. Based on the desired level of precision, it is recommended that printed models be produced at an inclination angle of 0°.
