Disclosed is a method for unpacking a component 11, produced by means of an additive manufacturing process, from a particulate material fill 9 of loose, unconsolidated particulate material, which is arranged together with the component 11 in a construction space 5 and surrounds the component 11. In order to unpack the component 11, the particulate material fill 9 surrounding the component 11 is transferred into a fluidized bed, so that the loose, unconsolidated particulate material is fluidized, and the fluidized, unconsolidated particulate material is drained downward off the construction space 5. In addition, a device for use in the method is described. |

1. A method for unpacking a component (11) produced by means of an additive manufacturing method from a particulate material fill (9) of loose, unconsolidated particulate material, which fill is arranged in a construction space (5) together with the component (11) and surrounds the component (11), wherein the construction space (5) is delimited downward by a construction platform (7) on which the particulate material fill (9) containing the component (11) is arranged,
wherein, for unpacking the component (11), the particulate material fill (9) surrounding the component (11) is transferred into a fluidized bed, so that the loose, unconsolidated particulate material is fluidized, and the fluidized, unconsolidated particulate material is drained downward through the construction platform (7) off the construction space (5), wherein for generating the fluidized bed, a fluid is introduced through the construction platform (7), into the particulate material fill (9) from below in such a way that the particulate material fill (9) is flown-through by the fluid bottom-up, and that the loose, unconsolidated particulate material is loosened up by means of the fluid and is fluidized, thereby forming a fluidized bed, and wherein one or more particulate material drain through-holes (13) are formed in the construction platform (7), which can be closed and opened selectively by means of a closing mechanism (17, 17′, 17″), and wherein the one or more particulate material drain through-holes (13) are opened by means of the closing mechanism for draining the fluidized, unconsolidated particulate material, so that the fluidized, unconsolidated particulate material drains off downward through the one or more particulate material drain through-holes (13). |
