Zusammenfassung:	A unitary swirler (200) is disclosed, comprising a body (201) having a swirler axis (11), and a plurality of vanes (208) arranged in a circumferential direction around the swirler axis (11), wherein the swirler (200) has a unitary construction. In one embodiment, the unitary swirler (200) has a rim (240) located coaxially with the swirler axis (11), and a wall (260) extending between a portion of the rim (240) and a portion of the hub (205). In another embodiment, the unitary swirler (200) has an adaptor (250) having a passage (254) that is configured to direct a flow of air towards at least some of the plurality of vanes (208). A method (500) for fabricating a unitary swirler (200) is disclosed, the method comprising the steps of determining three-dimensional information of the unitary swirler (200) having a plurality of vanes (208) arranged in a circumferential direction on a body (201) around a swirler axis (11) and a wall (260) extending between a rim (240) and a portion of the body (201), converting the three- dimensional information into a plurality of slices that each define a cross-sectional layer of the unitary swirler (200), and successively forming each layer of the unitary swirler (200) by fusing a metallic powder using laser energy. Exemplary embodiments are disclosed, showing a unitary swirler (200) made by using a rapid manufacturing process. In one aspect of the invention, the rapid manufacturing process is a laser sintering process. Linvention concerne une coupelle rotative unitaire (200), incluant un corps (201) possédant un axe de coupelle rotative (11) et une pluralité dailettes (208) agencées dans une direction circonférentielle autour dudit axe de coupelle rotative (11), ladite coupelle rotative (200) présentant une construction unitaire. Dans un mode de réalisation, la coupelle rotative unitaire (200) possède une périphérie (240) située coaxialement audit axe de coupelle rotative (11), et une paroi (260) sétendant entre une partie de ladite périphérie (240) et une partie du moyeu (205). Dans un autre mode de réalisation, la coupelle rotative unitaire (200) possède un adaptateur (250) présentant un passage (254) conçu pour diriger un écoulement dair vers au moins quelques ailettes de ladite pluralité dailettes (208). Linvention concerne également un procédé (500) de fabrication de ladite coupelle rotative unitaire (200), le procédé comprenant les étapes suivantes : détermination des informations tridimensionnelles sur ladite coupelle
