    Abstract: The invention relates to a device (1) for building a layer body (2) from a plurality of superimposed layers of free-flowing material, in particular particulate material, on a building platform (3) in a build space (4), the layers being solidified and joined to each other in locally predetermined areas, so that at least one layer body (2) is formed by the solidified and joined areas of the layers, including an elongated discharge container (5), which is movable back and forth over the build space (4]) in at least one discharge direction and which has at least one discharge opening (6) from which the free-flowing material is dischargeable in individual superimposed layers during the movement of the discharge container (5), it being possible to supply the discharge container (5) with free-flowing material from a filling device with at least one storage or filling container (10) having at least one outflow opening (11) by vertically covering the at least one outflow opening (11) of the storage or filling container (10) with an elongated feed opening (12) of the discharge container (5).The invention provides that the storage or filling container (10) has a shorter extension than the discharge container (5), viewed in the longitudinal direction of the discharge container (5), and the storage or filling container (10) is controllable relative to the discharge container (5), viewed in the longitudinal direction of the discharge container (5), in such a way that the outflow opening (11) of the storage or filling container (10) is guided along the feed opening (12) at least once from one end thereof to the other end thereof.

    Abstract: The invention relates to a device for constructing a laminar body from a plurality of superimposed layers of free-flowing material, in particular particulate material, and a build platform within a working area. The layers are solidified in locally predetermined regions by the action of binders and are joined together so that at least one moulded body is formed by the solidified and joined regions of the layers. The device comprises a discharging device movable back and forth over the working area in at least one discharge direction and having at least one discharge opening from which the free-flowing material can be discharged in individual superimposed layers during the movement of the discharging device.

    Abstract: The invention relates to a device (13) for constructing a laminar body (5) from a plurality of superimposed layers of free-flowing material, in particular particulate material, an a build platform (6) within a working area (11). The layers are solidified in locally predetermined regions by the actions of binders and are joined together so that at least one molded body (4) is formed by the solidified and joined regions of the layers. The device comprises a discharging device (1) movable back and forth over the working area (11) in at least one discharge direction and having at least one discharge opening (14) from which the free-flowing material can be discharged in individual superimposed layers during the movement of the discharging device (1). According to the invention at least one body (8, 8a) defining the working area (11) in at least one discharge direction of the discharging device (1) and the build platform (6) are adjustable vertically relative to each other in accordance with the specific progress with which the laminar body (5) is being constructed, in such a manner that a surface of the at least one body (8, 8a) facing the discharge opening (14) is aligned flush with a laminar body (5) topmost layer that is yet to be produced or has already been produced, in order to dose the discharge opening (14) of the discharging device (1) and prevent the discharging device from discharging free-flowing material or in order to discharge free-flowing material not used for the laminar construction into a collecting container (7) when the discharge opening (14) is located above the body (8, 8a).
