Resumen
This study provides a non-destructive evaluation to measure orthotropic material constants for additive manufacturing structures. The resonant frequencies obtained from experimental measurements were used to inversely calculate the engineering constants, Ex, Ey, Ez, Gyz, Gxz, and Gxy, from the eigenvalues of bending and torsion modes. The stiffness of the 3D-printed structure was determined by the dynamic testing method?s influence on layer height and raster angle. In the study, the stiffness can be designed in the 3D-printed structure as being manufactured.
