This study evaluated the surface quality of textile-like porous media fabricated by different 3D printing techniques using a 3D optical profilometer, with SLA technique producing the smoothest surface. The surface parameters of MJF samples were found to be lower than those of FDM samples, indicating a smoother surface in MJF production compared to FDM due to the different filling patterns.
The enhancement of surface roughness of a textile-like porous medium fabricated by 3D printing techniques is crucial for the repeatability of permeability experiments from test to test. This paper aims at comparison of the surface quality of textile-like porous media fabricated by Stereolithography (SLA), Fused Deposition Modeling (FDM), and Multi Jet Fusion (MJF) 3D printing techniques. Hence, a 3D optical profilometer was used to evaluate the 3D areal surface texture parameters of samples according to ISO 25178. The results revealed that SLA technique produces the smoothest surface with the lowest deviation in the measured values of the surface characteristics. Also, the surface parameters such as the average roughness (Sa) and root mean square (RSM) roughness (Sq) of the top surface of MJF samples are lower than those measured for FDM sample. Furthermore, filling pattern of the FDM technique as a trajectory filament-based AM process results in rougher horizontal surfaces compared to those produced by a non-trajectory powder-based process such as MJF.
