Fused deposition modeling(FDM) is a rapid prototyping technology that can directly print parts with complex geometrical shapes. However， it is hard to compare with the traditional processing methods in terms of vibration property， and a more practical analysis of vibration characteristics is needed. Therefore， a theoretical modeling method of vibration characteristics of the FDM 3D printed was proposed for the first time. The FDM sheet under the cantilever boundary conditions was taken as the research object. Based on the classical laminated plate theory， the vibration mode function was represented by the bidirectional beam function combination method， and the inherent characteristics of the composite thin plate were obtained by the Ritz method.The inherent characteristic test system of the FDM 3D printed plate was built， and the natural frequency and mode shape of the thin plate sample were obtained. The calculation and experimental results verify the correctness and reliability of the theoretical calculation method. [ABSTRACT FROM AUTHOR]
