Abstract

See full text

A method for producing a three-dimensional object by layer-wise applying and selectively solidifying a building material in powder form includes the steps of applying a layer of the building material over a working plane and selectively solidifying the layer at positions that correspond to a cross-section of the object to be produced by introducing energy and repeating the steps of applying and selectively solidifying until the object is completed. By doing so, the application step is carried out such that the application device moves at least twice over an area to be coated without an intermediate irradiation, and the step of selectively solidifying is carried out with an irradiation device that emits a radiation suited to solidify the building material.
