Abstract
La présente invention concerne un dispositif d’impression tridimensionnelle comprenant un système d’extraction chauffant qui comprend un conduit d’acheminement (1210) de matière fusible connecté en amont à un réservoir et en aval à une tête d’impression (1400) munie d’une buse, un organe de déplacement (1220) de ladite matière dans ledit conduit d’acheminement (1210) et un organe de chauffe (1230) agencé autour dudit conduit d’acheminement (1210) pour faire fondre ladite matière, ledit dispositif comprenant un système de refroidissement comportant une chambre de circulation (1110) d’un fluide gazeux de refroidissement agencée autour dudit conduit d’acheminement (1210), ledit fluide gazeux de refroidissement circulant depuis l’amont jusque l’aval dudit conduit d’acheminement (1210), ladite chambre de circulation (1110) présentant au moins une sortie aval orientée de manière à éjecter le fluide gazeux réchauffé sans interférer sur ladite tête d’impression (1400) en aval et sur l’espace externe environnant la sortie de buse. Figure de l’abrégé : [Fig. 3]
