Abstract

A method for a layer-wise manufacturing of a three-dimensional object has a first step of providing a layer of a material in powder form or a liquid material on a support or a layer that has already been solidified at selected positions previously and a second step of directing a focussed photon or particle beam (8′) selectively at selected positions of the layer. In the second step, the photon or particle beam is selected such that it brings about a change of the absorption of the material when hitting the layer. After the termination of the second step, a third step is carried out, in which the layer is irradiated by means of electromagnetic radiation (18′) such that the material is homogenously solidified at those positions of the layer that correspond to the cross-section of the object to be formed.
