Application of 3D Printing for Porous Models Simulation in Seismic Physical Modeling

In seismic physical modeling, it is important to design and manufacture the model. Conventional model method had limitations in manufacturing porous models to generate desired in-situ condition in subsurface sediment. However, it has become possible to construct porous models using 3D printing technique. In this study, the porosity of the physical model was controlled and applied to validation with seismic modeling using a 3D printing method. It was confirmed that the FDM method is a suitable 3D printing method for the porous model. The porosity properly was controlled and the P and S-wave velocities according to the porosity were analyzed using an seismic physical modeling.
