Abstract
Build material handling unit (2) for a powder module (3) for an apparatus for additively manufacturing three-dimensional objects, which apparatus is adapted to successively layerwise selectively irradiate and consolidate layers of a build material (4) which can be consolidated by means of an energy source, wherein the build material handling unit (2) is coupled or can be coupled with a powder module (3), wherein the build material handling unit (2) is adapted to level and/or compact a volume of build material (4) arranged inside a powder chamber (5) of the powder module (3) by controlling the gas pressure inside the powder chamber (5).
Claims15
A build material handling unit comprising:
- a powder module for an apparatus for additively manufacturing three-dimensional objects;
- a gas container;
- a connection plate;
- a sieve fluidly connected to the connection plate and configured to supply a build material through the connection plate;
- and
- a pump fluidly communicating the gas container to a powder chamber of the powder module through the connection plate,
- wherein the powder module is adapted to couple to or is coupled to the build material handling unit with the connection plate,
- wherein the build material handling unit is adapted to level and/or compact a volume of the build material arranged inside the powder chamber of the powder module by controlling a gas pressure inside the powder chamber with the pump, and
- wherein the connection plate is adapted to connect the build material handling unit with the powder module to seal an opening of the powder chamber of the powder module.
