Zusammenfassung:The invention concerns a bearing support (21) for an aircraft engine, manufactured, in one piece, by powder-bed additive manufacturing from a manufacturing platform (T), comprising a cylindrical element (23) including an annular stiffener (47) with a cross-section that changes along its circumference, this stiffener (47) being formed with alternating portions having a Γ-shaped cross-section (48), needing to be supported during the manufacture, and portions having a Y-shaped cross-section (51) that are not supported during the manufacture. L'invention concerne un support de palier (21) pour moteur d'aéronef, fabriqué d'un seul tenant par fabrication additive sur lit de poudre à partir d'un plateau de fabrication (T), comprenant un élément cylindrique (23) incluant un raidisseur (47) annulaire à section évolutive le long de sa circonférence, ce raidisseur (47) étant formé d'une alternance de portions à section en Γ (48) devant être supportées durant la fabrication et de portions à section en Y (51) non supportées durant la fabrication
