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: The present invention relates to an apparatus for dispensing fluids, especially particulate matter, from a supply bin. The apparatus includes a plough that is movable at least partially in and out of the bin and which, when retracted, closes a matching aperture in the bin, whereby there is an adequate quantity of fluid above the plough.
