Abstract
In the present work, the permeability of polymeric porous media produced by additive manufacturing (AM) in scaffolding structure is analyzed experimentally, numerically and theoretically, according to the permo-porous properties of the medium. The three-dimensional polymeric porous media are characterized by elliptical filaments equally spaced and alternated between layers (scaffolding). In the numerical and theoretical approaches the representation of the porous media is done using the concept of representative elementary volume (REV). In the experimental study the produced samples were tested using a liquid permeameter of steady-state permeability. The results obtained demonstrate an excellent precision in comparing experimental, numerical and theoretical approaches, and a numerical correlation for the permeability is proposed.
