Zusammenfassung:	A Method of additive manufacturing a thin-walled structure (11) out of a powder bed (6) by selective irradiation is described. The method comprises additively establishing a non-continuous support (12) for supporting the thin-walled structure (11) on a build plate (1), wherein non-continuous melt pools are generated in the powder bed, and additively establishing the thin-walled structure (11) on the support (12). Moreover, a component manufactured according to said method is described. L'invention concerne un procédé de fabrication additive d'une structure à paroi mince (11) hors d'un lit de poudre (6) par irradiation sélective. Le procédé comprend l'établissement de manière additive d'un support non continu (12) pour supporter la structure à paroi mince (11) sur une plaque de construction (1), des bassins de fusion non continus étant générés dans le lit de poudre, et l'établissement de manière additive de la structure à paroi mince (11) sur le support (12). De plus, l'invention concerne un composant fabriqué selon ledit procédé.
