Abstract: Disclosed is a coater assembly 1 for a 3D printer, comprising a coater 3 having a container 5 which defines an inner cavity for receiving particulate construction material which opens into a container opening 7 for outputting the particulate construction material from the container 5, and an output region 9 which defines a coater output opening 11 for outputting the particulate construction material from the coater 3 onto a construction field. The container 5 is movable relative to the coater output opening 11 so that by moving the container 5 relative to the coater output opening a discharge of particulate construction material from the inner cavity through the container opening 7 and the coater output opening 11 onto the construction field is variable.

Abstract: Disclosed is a method for unpacking a component 16 manufactured by means of a generative manufacturing process, from a particulate material fill 18. In the method, an auxiliary frame 20 having a vertical circumferential wall structure 22, open downward, is arranged above a vertical circumferential wall structure 12 of a construction box 10. In addition, a construction platform 14 of the construction box 10 is displaced upward, so that the particulate material fill 18 containing the component 16 is transferred from the construction box 10 to the auxiliary frame 20. In addition, the auxiliary frame 20 with the particulate material fill 18 containing the component, and the construction box 10 are moved away from each other, and the component 16 is unpacked from the particulate material fill 18 at least in part and is removed from the auxiliary frame 20.

Abstract: 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.
