Title (EN) COATING ARRANGEMENT FOR A 3D PRINTER
(FR) SYSTÈME DE REVÊTEMENT POUR IMPRIMANTE 3D
(DE) BESCHICHTERANORDNUNG FÜR EINEN 3D-DRUCKER
Abstract:
(EN) The invention relates to a coating arrangement (1) for a 3D printer, comprising a coater (3) with a container (5) defining an internal hollow space for receiving particulate building material, said internal hollow space leading into a container opening (7) for discharging the particulate building material from the container (5), and a discharge region (9) defining a coating discharge opening (11) for delivering the particulate building material from the coater (3) to a construction field. The container (5) is movable relative to the coating discharge opening (11) so that a discharge of particulate building material from the internal hollow space through the container opening (7) and the coating discharge opening (11) to the construction field can be varied by a movement of the container (5) relative to the coating discharge opening.
(FR) L'invention concerne un système de revêtement (1) pour une imprimante 3D, présentant un dispositif de revêtement (3) pourvu d'un récipient (5), qui définit un espace creux interne destiné à recevoir un matériau de construction particulaire et aboutissant dans un orifice (7) de récipient destiné à distribuer le matériau de construction particulaire à partir du récipient (5), ainsi que d'une zone de distribution (9) qui définit une ouverture de distribution (11) du dispositif de revêtement destinée à distribuer le matériau de construction particulaire depuis le dispositif de revêtement (3) sur une zone de construction. Le récipient (5) est mobile par rapport à l'ouverture de distribution (11) du dispositif de revêtement, de manière telle qu'un mouvement du récipient (5) par rapport à l'ouverture de distribution du dispositif de revêtement permet de faire varier une évacuation de matériau de construction particulaire depuis l'espace creux interne à travers l'ouverture (7) du récipient et à travers l'orifice de distribution (11) du dispositif de revêtement sur la zone de construction.
(DE) Offenbart ist eine Beschichteranordnung (1) für einen 3D-Drucker, aufweisend einen Beschichter (3) mit einem Behälter (5), der einen inneren Hohlraum zur Aufnahme von partikelförmigem Baumaterial definiert, der in einer Behälteröffnung (7) zum Ausgeben des partikelförmigen Baumaterials aus dem Behälter (5) mündet, und einem Ausgabebereich (9), der eine Beschichter-Ausgabeöffnung (11) zum Ausgeben des partikelförmigen Baumaterials aus dem Beschichter (3) auf ein Baufeld definiert. Der Behälter (5) ist relativ zu der Beschichter-Ausgabeöffnung (11) bewegbar, so dass durch ein Bewegen des Behälters (5) relativ zu der Beschichter-Ausgabeöffnung ein Austrag an partikelförmigem Baumaterial aus dem inneren Hohlraum durch die Behälteröffnung (7) und die Beschichter-Ausgabeöffnung (11) hindurch auf das Baufeld variierbar ist.
