Recent advances in 3d printer technology have made it possible to perform 3d printing using CFRTP (Carbon Fiber Reinforced Thermo Plastics). 3D printed CFRTP plate made by Mark Two (Markforged). The 3D printed CFRTP plate is made of by nylon resin including continuous carbon fiber. Our object is to reproduce vibration mode of the 3D printed CFRTP by the FE model in this research. The FE model has local coordinate systems along the fiber direction in the plate. The X direction of a local coordinate system fit to the direction of carbon fiber. The effect of the selection width of the diagonal elements on the vibration characteristics is investigated. When the selection range was large, the natural frequency was calculated to be high. But the vibration modes were not change. Comparing the experimental results with the analytical results, the best agreement was obtained when there was no coordinate conversion.
