Abstract
Additive manufacturing (AM) has the potential to be applied in many areas. Water filtration is critical, as access to clean and safe drinking water is a global concern. In this area, a crucial component is a filter, which is a porous media made of some specific materials. The porous structure and porosity of the filters are important for their efficiency. The use of AM to print special filters can improve efficiency, cost-effectiveness, customization, innovation, material development, and sustainability. Material extrusion (MEX) is an AM technology with great potential in this area. In this case, a stable and printable ceramic paste is paramount. Zeolites, with their unique structure and porosity, have been studied extensively for their potential use in water filtration. However, the AM of zeolites is a relatively new area of research. This research aimed to develop a porous media, based on zeolites produced through MEX. This paper addresses the preliminary challenge of creating a stable and printable ceramic paste of zeolite for water treatment proposals. Two assays, X-Ray Diffraction and Multi Pycnometer of Helium, were used to determine the necessary amount of water, dispersant, and plasticizer to create the ceramic paste. The procedure was then used to produce samples of zeolite scaffolds through MEX, and the resulting zeolites were sintered. The results demonstrate the feasibility of using the zeolite paste for MEX.
