ABSTRACT OF THE DISCLOSURE A method for producing a component of a separation element for separating a gaseous or vaporous mixture into fractions, which element is composed of a plurality of separating nozzle structures presenting passages defining mixture supply channels, separating chambers and fraction discharge channels, which method includes: forming a negative mold of the component by: providing a plate of a selected material whose ability to be removed from the plate is influenced by application of selected radiation; irradiating portions of the plate with such radiation in a pattern corresponding to the passages presented by the nozzle structure and to an extent such that material out- side of the regions delimiting the passages is removable more easily than material within those regions; and removing the more easily removable material from the plate to create the negative mold of the component and forming the component by: filling the openings in the negative mold with a second material to create a solid plate-shaped member; and removing the negative mold from the plate-shaped member.
