RT journal article T1 Assessment of the Development Performance of Additive Manufacturing VPP Parts Using Digital Light Processing (DLP) and Liquid Crystal Display (LCD) Technologies A1 Batista Ponce, Moisés A1 Mora Jiménez, Jairo A1 Salguero Gómez, Jorge A1 Vázquez Martínez, Juan Manuel A2 Ingeniería Mecánica y Diseño Industrial K1 additive manufacturing K1 DLP K1 LCD K1 metrology K1 photopolymerisation K1 quality K1 VPP AB Non-metallic additive manufacturing technology has seen a substantial improvement inthe precision of the parts it produces. Its capability to achieve complex geometries and very smalldimensions makes it suitable for integration into strategic industrial sectors, such as aeronautics andmedicine. Among additive manufacturing technologies, resin development processes demonstrateenhanced precision when compared to other methods, like filament printing. This study conductsa comparative analysis between digital light processing (DLP) and liquid crystal display (LCD)photopolymerization processes to assess the performance of the technologies and how processparameters affect the accuracy of the resulting parts. The research evaluates the impact of thediscretization process used during the digital model export, determining the optimal mesh size andthen analyzing the geometric deviations that occur by altering various operating parameters of theprocess. Statistical methods will be employed to identify the most significant parameters in themanufacturing process. Among other aspects, the precision of manufacturing technologies regardingthe movement axis has also been evaluated. Regarding the minimum size of the features that can befabricated, DLP technology has surpassed LCD technology, successfully producing features as smallas 200 μm, compared to 500 μm for LCD technology.
