Abstract: Powder module (1) for an apparatus for additively manufacturing three-dimensional objects, the powder module (1) comprising a powder chamber (6) having a power chamber volume (7) and a carrying device (9), the carrying device (9) comprising: a carrying unit (8) being moveably supported along a motion axis between a first position, particularly a lower end position, and a second position, particularly an upper end position, relative to the powder chamber (6), a drive unit (10) for generating a drive force for moving the carrying unit (8) between the first position and the second position or vice versa, a coupling unit (11) for coupling the carrying unit (8) with the drive unit (10), and a second extension state, particularly corresponding to the second position of the carrying unit (8), a guiding unit (12) surrounding the coupling unit (11).
