The device has application unit (7) for applying a layer of material such as polymer material onto the building platform (6). An irradiation device is provided with electromagnetic radiation emitting radiation source (1) and control unit (3), and located in the beam path of the electromagnetic radiation lens (8) for irradiating the object (5). The application unit is configured as doctor blade whose powder-facing edge is structured as a non-continuous straight line. The doctor blade is moved perpendicular to the direction of application and parallel to the plane of the building field. An independent claim is included for method for layer-by-layer production of three-dimensional object.
