Abstract
With the development of 3D printers, it has become possible to 3D print materials containing carbon fibers. In this study, FE model that can reproduce the vibration characteristics of a test plate made with the 3D printer Mark Two. This study aims to create FE model that can reproduce the vibration characteristics of a test plate made with the Mark Two 3D printer when it is subjected to central excitation. Currently, the model can reproduce the vibration modes but is not able to reproduce the natural frequencies. One possible reason for this is that the value of the material constants used in the material constants used in the analysis may differ from the actual ones. To ensure the accuracy of the material constants used, the output of the material constant by the simultaneous identification method using the differential evolution method with APDL were applied to improve the reproducibility of the natural frequencies.
