Here, we propose experiments that emulate processes that occur in disordered mesoporous media, on a
macroscopic scale, by using a special designed high-vacuum system and 3D-printed channels to
investigate features of complex porous media, such as fractal pores [3]. This set-up allows us to validate
Knudsen diffusion theory in complex geometries more directly than has ever been the case. Some
preliminary results will be shared, including features of the vacuum set-up, and Knudsen diffusion
results in channels of varying geometry, including channels with a 3D-printed fractal surface
