Device for building a multilayer structure with storage container or filling container movable along the dispensing container

Abstract

The invention relates to a device () for building a layer body () from a plurality of superimposed layers of free-flowing material, in particular particulate material, on a building platform () in a build space (), the layers being solidified and joined to each other in locally predetermined areas, so that at least one layer body () is formed by the solidified and joined areas of the layers, including an elongated discharge container (), which is movable back and forth over the build space (]) in at least one discharge direction and which has at least one discharge opening () from which the free-flowing material is dischargeable in individual superimposed layers during the movement of the discharge container (), it being possible to supply the discharge container () with free-flowing material from a filling device with at least one storage or filling container () having at least one outflow opening () by vertically covering the at least one outflow opening () of the storage or filling container () with an elongated feed opening () of the discharge container (). The invention provides that the storage or filling container () has a shorter extension than the discharge container (), viewed in the longitudinal direction of the discharge container (), and the storage or filling container () is controllable relative to the discharge container (), viewed in the longitudinal direction of the discharge container (), in such a way that the outflow opening () of the storage or filling container () is guided along the feed opening () at least once from one end thereof to the other end thereof.
