Abstract
A device and method for producing a green compact from a powdered or granular material by successive application and compression of the material, is disclosed. The device includes a fill shoe, which is filled with the material and is adjustable by an adjusting device, where a first park position is provided for the fill shoe. A matrix having at least one construction chamber is filled with the material layer-by-layer by the fill shoe between a first and second end position. A press having a lower punch and an upper punch, which are adjustable by a height adjustment device, compresses the material applied layer-by-layer in the at least one construction chamber. After filling the construction chamber with the material, the fill shoe is moved out of the second end position into a second park position, where the second park position is different from the first park position.
