A leveling slider exchange arrangement (12) for use in an apparatus (10) 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 (16) adapted to apply a raw material powder onto a carrier (18) and a leveling slider (40) adapted to level the raw material powder applied onto the carrier by means of the powder application device. An attachment mechanism (46) is adapted to releasably attach the leveling slider in a leveling slider attachment position (P) in the powder application device (16). A storage chamber (62) is adapted to store at least one exchange leveling slider (40'), the storage chamber being connected to a connecting channel (64) adapted to connect the storage chamber to the leveling slider attachment position (P) in the powder application device. A leveling slider exchange mechanism (70) is adapted to withdraw the exchange leveling slider from the
