Abstract
A filter, in particular for a rotary separator, is produced using an energy beam melting process, for example an electron beam, starting from powder made from the same material as a porous filtering portion to be formed, for example from a titanium alloy; on the basis of a three-dimensional model comprising a cell structure defining the porous filtering portion, subsequent layers of powder are applied and locally melted, so as to form successive sections of the porous filtering portion; at the end of the forming process, the residual powder is evacuated from the pores.
