  • Patent number: 10675814
    Abstract: An installation is provided for cleaning a plate used in an additive manufacturing process performed using a powder. The installation includes an entry lock, an exit lock, a dry cleaner, a wet cleaner, and a conveyor system. The entry lock is structured to accept into the installation a plate that is to be cleaned. The exit lock is structured to allow the plate to be extracted from the installation after cleaning. The dry cleaner is structured to clean the plate using vibrations and shocks in a first confinement enclosure. The wet cleaner is structured to clean the plate using at least one liquid in a second confinement enclosure. The conveyor system is structured to transport the plate between the dry cleaner, the wet cleaner, and the exit lock.

  • Patent number: 10603695
    Abstract: A device is provided for dry cleaning a plate used in an additive manufacturing process that involves powder. The device includes a confinement enclosure, a loader, and a dry-cleaning station. The confinement enclosure includes an entry lock through which a plate to be cleaned enters. The loader is located within the confinement enclosure and is structured to receive and transport the plate. The dry-cleaning station is located within the confinement enclosure and is structured to dry clean the plate. The dry-cleaning station includes a vibration device, which imposes vibrations on the plate, and a shock device, which causes the plate to experience shocks.

  • Patent number: 10413968
    Abstract: The machine presents a working zone that is defined in an upper part of a build sleeve which is fixedly mounted in a chassis. Within the working zone, the object is supported by a build plate which slides inside the build sleeve when driven in vertical translation by the head of an actuating cylinder which is placed along a central axis of the sleeve. The build plate is positioned inside a transport container which is arranged removably between the sleeve and the actuating cylinder. The machine also includes a means for moving the transport container vertically into contact with the build sleeve. The container is open at its top and at its bottom so that, when the actuating cylinder is actuated, the head thereof can transfer the plate between the transport container and the build sleeve which forms a build envelope around the plate.
