Abstract | The scattering of acoustic waves propagating in porous rigid 3D stereolithographical materials that are made of resin, has been investigated. 3D stereolithographical (STL) materials were obtained using a form of rapid prototyping that allows complex solid objects to be manufactured directly from3D computer models in the form of successive layers of light-cured resin. Relative variation of velocity and attenuation of 3D materials in air filled and water filled media has been predicted at normal and oblique directions. The scattering perturbation is similar to diffusion waves at low frequency while dispersion velocity and attenuation change with respect to square root of angular frequency and with respect to angular frequency at high frequency respectively. |
