A method and system for manufacturing three-dimensional porous structures. Filaments are deposited in a predetermined interconnected arrangement in a plurality of stacked layers for forming a porous structure with interconnected pores. Furthermore, the porous structure is subjected to a heat treatment in a heat chamber in order to reduce a moisture, solvent and/or organic material, solvent or organic material content (drying and/or calcination) of the porous structure by irradiating microwave energy through said porous structure. The applied microwave energy is selected based on the structural interconnected arrangement of the deposited filaments defining the shape and size of the pores of the three-dimensional porous structure.
