Abstract—

This paper presents the results of measuring the second- and third-order elastic coefficients of a 3D-printed 3D-printed sample of Anycubic Basic photopolymer using the Thurston–Brugger quasi-static method. This method is based on measuring the dependences of the relative change in the velocity of shear and longitudinal ultrasonic waves on the uniaxial compression pressure applied to the sample. The elastic moduli were determined for three different directions of propagation of an ultrasonic wave that made it possible to estimate the elastic anisotropy of the properties of the tested material both in linear and nonlinear approximations.
