A filter (4), in particular for a rotary separator (1), 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 (10) 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 (10), subsequent layers of powder (22) are applied and locally melted, so as to form successive sections (170) of the porous filtering portion (10); at the end of the forming process, the residual powder is evacuated from the pores. |
