Abstract: A door drive apparatus for adjusting a vehicle door relative to a vehicle body including an adjustment part for power transmission between the vehicle door and the vehicle body, a drive motor and a gear assembly coupling the drive motor to the adjustment part. The gear assembly includes a guide rail and a sliding element guided longitudinally on the guide rail along an adjustment direction, which is adjustable by the drive motor and is coupled to the adjustment part, and the guide rail includes two legs extended parallel to each other along the adjustment direction and the sliding element is guided between the legs along the adjustment direction.

Abstract: Powder module device (1) for an apparatus for additively manufacturing three-dimensional objects by successive layerwise selective irradiation and consolidation of layers of a powdered build material (2). The device includes a powder module (3), comprising a powder module base body (6) to receive a powdered build material (2), comprising wall elements; delimiting a build material receiving volume (9) for receiving a powdered build material (2) and an opening (10) for introducing powdered build material (2) into the build material receiving volume (9); a lid (4), comprising a lid base body (11) connected to the powder module base body (6) so as to close the opening (10) of the powder module base body (6) in a closed state of the powder module device (1); and a sealing device (5) configured to seal between the powder module (3) and the lid (4) in the closed state of the powder module device (1).

Abstract: Module (5) for an apparatus (1) for additively manufacturing of three-dimensional objects (2) by means of successive layerwise selective irradiation and consolidation of layers of a build material (3) which can be consolidated by means of an energy source (4), in particular the module (5) is mountable in or mounted in a process chamber (6) of an apparatus (1), which module (5) comprises a module build chamber (8) and a module dose chamber (7), wherein a module build plate carrier (12) moveable relative to at least one module build chamber wall (13) and a module dose plate carrier (10) moveable relative to at least one module dose chamber wall (11) are provided, wherein a lever device (14) mechanically linking the module build plate carrier (12) with the module dose plate carrier (10) is provided.
