Abstract

A device for producing three-dimensional objects by successively solidifying layers of a construction material that can be solidified using radiation on the positions corresponding to the respective cross-section of the object, with a housing comprising a process chamber, a construction container situated therein, an irradiation device for irradiating layers of the construction material on the positions corresponding to the respective cross-section of the object, an application device for applying the layers of the construction material onto a carrying device within the construction container or a previously formed layer, a metering device for delivering the construction material, wherein the application device comprises a coating element which distributes the construction material delivered by the metering device as a thin layer in an application area along a linear application movement, wherein at the end of a coating process for a layer when returning the coating element 11 to a coating starting position.
