Problems solved by technology

[0005] Disadvantageously, the distribution of build material remains uneven after it pushes against the roof
Additionally, the build material is pushed and compacted unevenly
Furthermore, due to the further step of pushing the build material against the roof, the powder space cannot be fully utilized, since still a portion of the powder space must remain available to move the movable element inside the powder space and push the build material against the roof

Abstract

Powder module (1, 15, 24) for an apparatus for additively manufacturing of three-dimensional objects is provided and comprises a powder chamber (2) defining a powder room (3), which is fillable with building material (4) in powder form and a cover (5) defining the powder room (3) at its top, whereby the powder module (1, 15, 24) comprises at least one equalization unit (7), configured for spreading the building material (4) inside the powder room (3).

Description

technical field [0001] The invention relates to a powder module of a device for the additive manufacturing of three-dimensional objects, comprising a powder chamber delimiting a powder space which can be filled with building material in powder form, and a cover delimiting the powder space on the top side. Background technique [0002] Powder modules of this type are well known and established in the art. In the context of the present invention, a powder module refers to a metering module for transferring building material into a process chamber of a plant for additive manufacturing and an overflow module for collecting excess building material transferred from the process chamber . The powder module may contain building material in powder form, the building material being accommodated in the powder space. The powder space is delimited by the walls and the bottom of the powder chamber, the powder space is covered on the top side by a cover or roof. Furthermore, such a powd...
