Title (EN) APPLIANCE FOR MANUFACTURING A THREE-DIMENSIONAL OBJECT BY MEANS OF AN ADDITIVE MANUFACTURING METHOD, AND ASSOCIATED ADDITIVE MANUFACTURING METHOD
(FR) APPARAEIL DE FABRICATION PAR MÉTHODE DE FABRICATION ADDITIVE D'UN OBJET TRIDIMENSIONNEL ET MÉTHODE DE FABRICATION ADDITIVE ASSOCIÉE
Abstract:
(EN) The invention relates to an appliance for manufacturing a three-dimensional object by means of selective additive manufacturing, comprising, in a housing: a support for depositing successive layers of additive manufacturing powder; a distribution arrangement designed to apply a layer of powder to said support or to a previously consolidated layer; and at least one source for the selective consolidation of a layer of powder applied by the distribution arrangement, characterised in that it comprises at least one protection element designed to trap, by electrical polarisation, ions of loaded vapour in the housing, said element consisting of a material designed to be electrically polarised and arranged in the vicinity of at least one optical/electronic module and/or component to be protected from the deposits, the appliance also comprising a polarisation assembly designed to ensure the electrical polarisation of said protection element during additive manufacturing operations.
(FR) 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 adaptée à la consolidation sélective d'une couche de poudre appliquée par l'arrangement de distribution, caractérisé en ce qu'il comporte au moins un élément de protection adapté pour piéger par polarisation électrique des ions de vapeur chargée dans l'enceinte, ledit élément étant en un matériau apte à être électriquement polarisé et étant situé au voisinage d'au moins un module et/ou composant optique/électronique à protéger des dépôts, l'appareil comportant en outre un montage de polarisation adapté pour assurer la polarisation électrique dudit élément de protection lors d'opérations de fabrication additive.
