Measurement of Orthotropic Material Constants and Discussion on 3D Printing Parameters in Additive Manufacturing

In this study, the orthogonal mechanical properties of additive manufacturing technology were explored. Firstly, six test pieces different stacking methods printed with a 3D printer, based on fused deposition modeling. The resonance frequency was measured by laser Doppler vibrometer as piece struck steel ball, which used to calculate orthotropic material constants. accuracy these constants then verified using finite element software through comparison experimental results from multiple natural modes. Thus, set for measurement and simulation verification established. Only three specific specimens are needed determine vibrating sensor technique, instead universal testing machine. We also analyzed influence printing parameters, including raster angle layer height, pieces. indicate that 0° leads highest Young’s modulus, 45° shear modulus G, height 0.15 mm strength. various stack conditions, fuse can be inversely calculating domain transformation.
