Abstract: The invention relates to a construction box (200) comprising a front wall (220), a rear wall and two side wails (224, 226), which delimit a construction box interior that houses a height-adjustable construction platform (210). The construction box (200) has dedicated travelling gear (250) integrated in to the construction box for propelling said box (2000 between a construction position, in which the construction box (2000 is positioned within the frame (150) of the system (100) to allow the shaped body to be built up and an additional construction box position, such as a construction box unpacking position, in which the construction box (200) is propelled out of the frame (150) of the system (100) to permit the unpacking of the built-up shaped body.

Abstract: An interchangeable container for a system for building a mold body by forming superimposed layers of granular material, the granular material locally and selectively hardened layer by layer. The container includes a bottom structure that is displaceable in the interior of the container in a direction in parallel with the container side walls and at least one spindle drive having a vertical screw spindle rotatably mounted in a container side of the container, and a spindle screw nut on which the bottom structure is supported. The bottom structure can be lowered step by step in the interior of the container by the spindle drive.

Abstract: The invention relates to a method and a device for applying for a flowable material, especially a particulate material, in individual superimposed layers across a support (50), the flowable material being first filled from a stationary feed station (10) into a storage container (24) of an application device. In the application device (30), which travels back and forth across the support, the flowable material is distributed inside the storage container across the entire length of the device and is then metered through a slot into a metering shaft in such a manner that the filling level in the metering shaft remains constant during application of the flowable material from the metering shaft onto the support.

Abstract: An interchangeable container (10) for a system for building a mold body by forming superimposed layers of granular material, the granular material locally and selectively hardened layer by layer, the container including a bottom structure (14) that is displaceable in the interior of the container in a direction in parallel with the container side walls, the container further including at least one spindle drive comprising a vertical screw spindle (20) which is rotatably mounted in a container side of the container (10), and a spindle screw nut (22) on which the bottom structure (14) is supported, such that the bottom structure can be lowered step by step in the interior of the container by means of the spindle drive.
