The method includes depositing (110) a layer of powder on a build plate or on a layer from at least one previous manufacturing step on the build plate, wherein the layer of powder comprises a high-Z material powder. Furthermore, the method includes selectively melting (120) and solidifying the powder to form septa wall structures (20) by scanning an electron beam in a spot sequence on the layer of powder to sequentially expose a plurality of spots (40) on the layer of powder to an electron beam spot. A size of the electron beam spot is at most 150 μm in diameter, preferably at most 75 μm in diameter, and more preferably at most 50 pm in diameter. The high-Z material powder comprises a high-Z material having an atomic number Z of at least 40, and preferably at least 70. The invention also relates to a microstructure for selective transmission of X-ray or gamma-ray radiation, which microstructure has been obtained by the method, and to an imaging component comprising such microstructures. The invention also relates to a method for manufacturing an imaging component.
