This paper presents a method for determining elastic constants — the elastic modulus and Poisson's ratio of 3D-printed materials using uniaxial tension test on rectangular cross-section samples. It is proposed to conduct longitudinal and transversal strain measurements on the surface of the samples using fiber-optic sensors based on fiber Bragg gratings, which offer comparable accuracy to standard electrical strain gages while providing advantages such as reduced size, simplified preparation, and minimal equipment requirements
