Abstract

Additive manufacturing is used increasingly for functional products and, consequently, the mechanical characterisation of the produced component has become a highly investigated topic. However, experimental routines consist mainly of tensile tests with standardised specimens and investigations focus on how process and design parameters, for example infill pattern, infill ratio, layering direction, affect the tensile modulus, ultimate elongation and strength.

In many cases, 3D printed components are subjected to static and/or dynamic bending operational loads and the flexural modulus should be identified. In polymers this can be significantly different, with an expected value between tensile and compressive moduli. Additionally, if the loading on the structure is dynamic (steady state or transient), dynamic (or vibratory) properties of the 3D printed structure become important. The present investigation focuses on methods for the experimental measurement of the flexural modulus under quasi-static and, more importantly, dynamic excitation. A range of structural approximations/numerical models are compared to identify the most suitable in providing the flexural modulus in a consistent manner.
