| Abstract Scope |
As designers and engineers continue to explore innovative applications for 3D printed materials, it is important to ensure that these fabricated parts possess mechanical resonant frequencies that match those fabricated from traditional processes. The objective of this investigation is to determine the relationship between 3D printing layer height and the vibrational response for fused deposition modeled (FDM), polylactic acid (PLA), 3D-printed, thin rectangular plates. Experimental and computational analyses are performed to describe the free vibration of centrally clamped plates with free edge boundary conditions on all four sides indicated (FFFF). It is concluded that by decreasing the fabrication layer height, an approximately 3% deviation in the accepted resonant frequency in the 3D printed rectangular plate is approached. It is believed that as the layer height decreases, the number of connections in the plates increases, resulting in the increase of homogenous tendencies within the plate body. |
