Claim 12:
13. The performer according to claim 12, wherein the additive manufacturing is produced by successive layers created progressively in a direction of manufacture which corresponds to the common direction of flow starting from a base plane which is normal to the common direction of flow,
wherein at least part of the first partition, at least part of the second partition, or at least a part of both the first and second partitions have inclination relative to the common direction of flow, and thus relative to the direction of manufacture, such that superimposition of the successive layers forms steps, and
wherein the preformer retains permanently, along the parts inclined in steps, an arithmetical roughness Ra which is between 4 μm and 30 μm, and which corresponds to coarse additive manufacturing roughness defined by the steps.
