Abstract
A powder discharge unit for equipping and/or upgrading a device for generatively manufacturing a three-dimensional object by a selective layer-by-layer solidification of building material in powder form includes a powder container for receiving building material in powder form and a filling chamber for filling in building material in powder form into the powder container. The powder discharge unit is configured to fluidise the building material in powder form in the powder container and the building material in powder form in the filling chamber independently of one another.
