Abstract: The present invention relates to a method for producing three-dimensional objects based on computer-provided data, whereby a material is deposited in layers in a process chamber and the material is selectively solidified and/or bonded using a bonding apparatus and/or a solidifying apparatus in the process chamber, these steps being repeated. A conveyance of the material proceeds during the build process and proceeds continuously, sequentially and evenly up to an unpacking position.

Abstract: The present invention relates to a device for manufacturing three-dimensional models by means of a 3D printing process, whereby a build platform for application of build material is provided and a support frame is arranged around the build platform, to which said support frame at least one device for dosing the particulate material and one device for bonding the particulate material is attached via the guiding elements and the support frame is moveable in a Z direction, which essentially means perpendicular to the base surface of the build platform. In so doing, the device provides a material feeding device having a particle material container to supply particulate material in batches from the storage area to the dosing apparatus and to do so with the least possible amount of shearing forces and without significant interaction with the atmosphere.

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 (11 [sic; 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.
