    Abstract: A leveling slider exchange arrangement for use in an apparatus for manufacturing three-dimensional work pieces by irradiating powder layers with electromagnetic radiation or particle radiation, the leveling slider exchange arrangement comprises a powder application device adapted to apply a raw material powder onto a carrier and a leveling slider adapted to level the raw material powder applied onto the carrier by means of the powder application device. An attachment mechanism is adapted to releasably attach the leveling slider in a leveling slider attachment position in the powder application device. A storage chamber is adapted to store at least one exchange leveling slider, the storage chamber being connected to a connecting channel adapted to connect the storage chamber to the leveling slider attachment position in the powder application device. A leveling slider exchange mechanism is adapted to withdraw the exchange leveling slider from the storage chamber, to move the exchange leveling slider to the leveling slider attachment position in the powder application device via the connecting channel and to bring the exchange leveling slider into engagement with the attachment mechanism.

    Abstract: An apparatus for producing a three-dimensional work piece, the apparatus comprises a process chamber accommodating a carrier for receiving a raw material powder, an irradiation device for selectively irradiating electromagnetic or particle radiation onto the raw material powder on the carrier in order to produce a work piece made of said raw material powder by an additive layer construction method, a first gas inlet for supplying gas to the process chamber and a gas outlet for discharging gas from the process chamber, wherein the first gas inlet and the gas outlet are configured and arranged in such a manner that a first gas flow across the carrier is generated, a transmission element which allows the transmission of the electromagnetic or particle radiation emitted by the irradiation device into the process chamber, and a second gas inlet for supplying gas to the process chamber, wherein the second gas inlet is configured and arranged in such a manner that a second gas flow in a direction facing away from the transmission element is generated.

    Abstract: A carrier arrangement (30) comprises a carrier element (34) having a carrier surface (36) and a plurality of supporting elements (38) attached to the carrier element (34), wherein each supporting element (38) has a supporting surface (40) extending from the carrier surface (36) of the carrier element (34) and being adapted to interact with a first surface (42) of a component (32) to be repaired. The carrier arrangement (30) further comprises a plurality of clamping elements (44), wherein at least a part of the clamping elements (44) are releasably attachable to the carrier element (34) in such a manner that a clamping surface (46) of the clamping elements (44), which is adapted to interact with a second surface (48) of a component (32) to be repaired, faces the supporting surface (40) of an associated supporting element (38) so as to sandwich the component (32) to be repaired therebetween in such a manner that the component (32) is fixed to the carrier element (34) with a repair site (50) of the component (32) facing away from the carrier surface (36) of the carrier element (34). A fastening device (72) of the carrier arrangement (30) is adapted to interact with a corresponding fastening device (74) of an apparatus (10) for repairing components (32) by selectively irradiating layers of a raw material powder applied to the repair sites (50) of the components (32) with electromagnetic or particle radiation.
