Lattice structure has drawn much attention to researcher due to its vast advantages such as lightweight and high strength to weight ratio. This study presents the preliminary study on the effect of hollow struts of body-centered-cubic (BCC) lattice structure on the natural frequency values vibration characteristic. The samples in this study were made by using fused deposition modeling (FDM) additive manufacturing into cubic and bar samples for compression and vibration test respectively. As expected, through compression test, it was found sample with highest solid strut diameter produced the highest stiffness value followed by hollow strut of the same strut size with 2 mm wall thickness and lastly solid sample with smaller strut diameter size. Meanwhile from vibration test it was found sample with hollow strut produced comparable natural frequency values as sample with highest strut diameter size despite of smaller stiffness.These results suggest that in order to have higher natural frequency values, hollow struts lattice is preferable as it can produce similar natural frequency values with adequately less mass which in the end can reduce cost and material consumption.
