Abstract:
1. A device for producing an object by a production method comprising: a material reservoir, for storing a powdered or granular material, a construction platform, and a device for feeding a layer of the powdered or granular material onto the construction platform or onto at least one material layer located on the construction platform, the device for feeding the layer of the material being linearly movable along a motion plane, along which the material reservoir and the construction platform are positioned adjacent to one another and which can be deflected orthogonally thereto, and wherein the device for feeding the layer of the material includes a circulating band stretched around at least two bodies, which at least in segments press against at least two bodies; a drive for moving the band around the at least two bodies; the circulating band includes a band segment fixedly assignable relative to at least one body in a direction of motion of the band around the at least two bodies; the band segment has a surface area facing toward the material reservoir and the construction platform and is inclined in relation to the motion plane by an angle and encloses a wedge-shaped spatial region between the band surface area and the motion plane; and at least a part of the band segment contacts the powdered or granular material stored in the material reservoir during linear motion of the segments from the material reservoir to the construction platform so that at least a portion of material in the reservoir is stripped off from the material reservoir so that at least the portion collects in the wedge-shaped spatial region and is deposited in a material layer on the construction platform to form a compressed material layer.
