3D print of an PLA beam with honeycomb

What is it about?

Research shows a lack of vibration analyses of structures produced by 3D printing. This study, therefore, investigates the vibration behavior of honeycomb structures made of polylactic acid (PLA) using the additive manufacturing process fused deposition modeling (FDM) in a beam element. Based on an experimental modal analysis and the determination of the damping rate, a FEM reference simulation model is created, and the results are validated with the data from the experiment. The original honeycomb structure was numerically varied in its density, i.e., in the thickness (t) of the cell wall, in the length (L) of the regular hexagons, and in its degree of filling. The results showed that the density of the honeycombs at a filling level of 19% has a marginal influence on the vibration behavior. The vibration behavior was reduced only when the filling level was increased to 30%. This study has implications for many areas of research in which vibrations play a significant role in technical applications. These findings highlight the potential for integrating renewable energy applications with sustainable solutions, emphasizing the importance of vibration dynamics in advancing environmentally friendly technologies.
