摘要： The invention relates to a method for the layered production of a three-dimensional object. Said method consists of a first step wherein a layer of a powered or liquid material on a carrier or a layer already compacted in selected locations is prepared and a second step consists of the selective direction of a focused photon beam or partial beam (8') on the selected locations of the layer. In the second step, the photon beam or the partial beam is selected in such a manner that it evokes a modification of the absorbency of the material during impact on the layer. After completion of the second step, a third step is carried out in which the layer is irradiated with electromagnetic radiation (18') in such a manner that the material is compacted in a homogenus manner in the locations of the layer that correspond to the cross-section of the object that is to be formed.

摘要： A process is disclosed for producing a three-dimensional object. Individual layers (6a, 6b, 6c, 6d) of an object made of a material hardenable by electromagnetic radiation are successively hardened by exposure to electromagnetic radiation (8, 10). A polymer blend (3) is used, so that the process is simplified and the properties of the object (6) to be formed may be influenced to a large extent by an appropriate selection of the polymer blend or proportions of the ingredients of the polymer blend.

摘要： 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.
