Abstract


This study investigates 3D printing advancements for low-speed aerodynamics in vehicle ventilation, focusing on accuracy and precision. Surface rugosity and dimensional measurements of 3D-printed air diffusers were conducted using advanced technologies. Surface roughness parameters were evaluated, revealing variations among printing techniques. 3D scanning was used for comparing the dimensional data, highlighting inconsistencies in FDM, SLS, and DLP methods, while SLA exhibited superior accuracy. Notably, SLA printing demonstrated minimal deviations, emphasizing its potential to enhance aerodynamic performance. This research underscores the significance of precision in 3D printing for optimizing vehicle ventilation and air quality. The findings suggest that SLA technology holds promise for revolutionizing automotive ventilation systems, offering improved functionality and driving experience.
