- Abstract
This pilot study investigates the impact of the 3D printing angle in the process of fabricating models obtained after intraoral scanning. The purpose of the research was to evaluate how the printing angle influences the precision, costs, material consumption, and fabrication duration of the models. Three intraoral scans were used, and pairs of stl files (upper and lower jaw) were prepared for printing (upon model bases design). The models were printed using a fast-curing resin, at different angles (0°, 30°, 60°, and 90°), maintaining a constant layer thickness of 0.1 mm. A total of 24 models resulted, which were scanned using the same intraoral scanner, and the obtained stl files were compared with the original ones, using Geomagic Control X software, to assess deviations. The results showed that the printing angle significantly influences the printing time, cost, quantity of resin, and overall deviation. It was observed that the 30° angle offered the smallest global deviation from the original model, indicating higher precision. Regarding costs and material consumption, these were minimal for models printed at a 90° angle. The 0° printing variant proved to be the fastest, offering an advantage in terms of time efficiency. Despite the limitations, mostly related to the small number of models analyzed, it can be concluded that choosing the printing angle is a crucial factor in optimizing the manufacturing process of dental models through stereolithography technique. All produced models, regardless of the printing angle, fell within the clinically acceptable accuracy limits, highlighting the practical applicability and efficiency of this technology in dental laboratory settings.
