1. A powder module for an apparatus for additively manufacturing three-dimensional objects, the powder module comprising:
a carrying element configured to receive a build plate, the build plate supporting powder material that is selectively consolidated during an additive manufacturing process to additively manufacture a three-dimensional object;
one or more clamping units configured to clamp the build plate to the carrying element; and
one or more moving units configured to move the one or more clamping units between an unclamped position and a clamped position, the unclamped position comprising the one or more clamping units being disconnected from the build plate, and the clamped position comprising the one or more clamping units being connected with respective ones of a corresponding one or more recesses in the build plate.
