1. A method of manufacturing three-dimensional porous structures, the method including:
providing a paste composition comprising particles of at least one inorganic material, at least one polymeric binder and at least one solvent,
depositing filaments of the paste composition in a predetermined interconnected arrangement in a plurality of consecutively stacked layers for forming a three-dimensional porous structure with interconnected pores between the filaments,
subsequently drying the deposited three-dimensional porous structure by subjecting the porous structure to a heat treatment by irradiating microwave energy through said porous structure, wherein the applied microwave energy employed during the heat treatment is tailored based on at least the relative spatial positioning and orientation of the filaments forming the three-dimensional porous structure.
