Optical and ultrasound transmission through additively printed transparent polymer

This paper presents the optical and acoustic characterization of an additively printed transparent polymer. Digital light processing DLP technic is used for printing transparent polymer when the acoustic and optical transmission were measured by ultrasonic transducers and UV spectroscopy. The 3D acoustic characterization of the polymer has shown slight anisotropic behavior with a longitudinal and shear velocities of 2488 m/s and 1133 m/s respectively. On the other hand, an anisotropic optical transmission and reflection have been shown. The obtained results are interesting in the development of acoustical and optical devices.
