3D-printing enables the fabrication of membranes with desired shapes and geometrical parameters. In this study, a membrane for pressure-driven processes was manufactured in single step using fused deposition modeling (FDM) technique. The produced from mixture polylactic acid (PLA) sucrose as pore-forming agent. Sucrose removed final by washing it water. consists three layers, sandwich-like structure ensures its mechanical stability. material obtained characterized SEM AFM imaging, well nitrogen adsorption-desorption contact angle measurements. porosity each layer is due to loose region, which coated on both sides dense film formed during printing. pores responsible rejection capability can be found grooves between polymer stripes layer. exhibits water permeability 64 L m−2h−1bar−1, molecular weight cut-off 69 kDa. PLA used polyphenol concentration, demonstrating 2–3.4 m−2h−1bar−1 selectivity towards these compounds 78–98% at 0.5 bar, flux decline ratio up 50%.
