Research Experiences for Undergraduates (REU), NHERI 2023: Assessing the Effect of 3D Printed Model Quality on Wind Pressure Distribution

3D printed models are commonly used in small scale wind tunnel testing. However, print quality can vary depending on 3D printer, nozzle size, and setting chosen. This paper investigates the effect 3D print quality has on the wind pressure distribution of models. The data in this project can be reused as a foundation for a more comprehensive study that involves a complete group of models with a higher number of pressure taps to confirm results. This project is unique because currently, there are not many studies on how the effect structure roughness has on small scale wind tunnel measurements. The audience is those conducting wind research.
