This paper aims to focus on the preparation of a cation exchange filament for three-dimensional (3D) fused deposition modeling (FDM). The polymeric binder was mixed with the selected conventional cation exchange resin and a filament was prepared using a mini extruder. Filaments were tested by mechanical properties, chemical properties, quality and melt flow index. Samples were prepared from granulate using a press, which were tested for electrochemical properties, thermal properties. The best result of ion exchange capacity (IEC) up to 3.0 meq/g of the dry matter was achieved with filament fill 65%. Permselectivity results above 90% were determined for 55%–65% filling of the cation exchanger. The results obtained are a promising step for the preparation of 3D printed cation exchange membranes (CEMs) with a defined structure.,The prepared granulates and filaments were evaluated using mechanical, rheological and thermal properties.,The prepared cation exchange filament can be used for the 3D printing process. The best result of IEC up to 3.0 meq/g of the dry matter was achieved with filament fill 65%. Permselectivity results above 90% were determined for 55%–65% filling of the cation exchanger, and area resistances 3.0 Ocm2 and specific resistances around 57 Ocm for 65% filling of the cation exchanger. The results obtained are a promising step for the preparation of 3D printed CEMs with a defined structure.,The prepared cation exchange filament.
