The additive manufacturing of model geomechanical materials has primarily been made from gypsum or plastics, due to availability of technology and a focus on dimensional control. Our work involves rethinking binder-jetting technology in order to re-task additive manufacturing and fabricate model sandstone from silica feedstock, which will allow for geomechanical analysis in comparison to natural sandstone. A major goal of the work is to be able to quantify the material properties of the binder phase joining the silica particles (a thermosetting acid-catalyzed polymeric resin) using atomic force microscopy and nanoindentation, which can then be input into finite element analysis simulations of rock masses. With this work, the aim is to be able to representatively print model sandstone in large statistical sample sizes for future study of predicting behavior knowing material properties of the constituent materials.
