Abstract

L'invention concerne un appareil pour fabriquer un objet tridimensionnel par fabrication additive sélective comportant dans une enceinte, un support pour le dépôt des couches successives de poudre de fabrication additive, un arrangement de distribution adapté pour appliquer une couche de poudre sur ledit support ou sur une couche précédemment consolidée, au moins une source de faisceau d'électrons adaptée pour assurer la consolidation sélective d'une couche de poudre appliquée par l'arrangement de distribution et une électronique pour la commande et l'alimentation de ladite source, caractérisé en ce que ladite source est une source de faisceau d'électrons à cathode à chauffage indirect, ladite source comportant un filament (22) de chauffage situé derrière la cathode (21) de ladite source par rapport au sens d'éjection et d'accélération des électrons par ladite cathode (21).
