Publication number: 20220274323Abstract: A method of manufacturing an object (3) in a build area (22) by means of a successive layer-by-layer solidification of a building material in powder form (18) comprises the steps: a) applying a layer of the building material in powder form (18) having a predetermined thickness d2 onto a layer of the building material already previously applied which has been solidified in a region corresponding to a cross section of the object (3), wherein, for applying the building material (18), a recoater (5, 15) is moved in a direction (B) across the layer already previously applied, and b) selectively solidifying the building material (18) applied in step a) in a region corresponding to a cross section of the object (3), wherein, prior to the application of a layer, for a solidified region having a thickness d1 in the layer applied before, the maximum (MAX) of the product of the extension of this solidified region in movement direction (B) of the recoater (5) and the thickness d1 is determined and during the applicatiType: ApplicationFiled: May 16, 2022Publication date: September 1, 2022Applicant: EOS GmbH Electro Optical SystemsInventors: Andrë Danzig, Rainer Salzberger, Jochen Philippi, Andreas Baumann, Gerd Cantzler, Robert Jelin

Patent number: 11364678Abstract: A method of manufacturing an object comprises applying a layer of building material in powder form having a predetermined thickness onto a layer of the building material already previously applied which has been solidified in a region corresponding to a cross section of the object. A recoater is moved in a direction across the layer already previously applied, and the building material is solidified in a shape corresponding to a cross section of the object. Prior to the application of a layer, for a solidified region having a thickness in the layer applied before, the maximum of the product of the extension of this region in movement direction of the recoater and the thickness is determined and during the application of the layer, at least an additional powder amount proportional to the value of the maximum is additionally provided.Type: GrantFiled: July 8, 2016Date of Patent: June 21, 2022Assignee: EOS GmbH Electro Optical SystemsInventors: Andrë Danzig, Rainer Salzberger, Jochen Philippi, Andreas Baumann, Gerd Cantzler, Robert Jelin

Publication number: 20210187617Abstract: Method for manufacturing a three-dimensional object by layer-wise application and selective solidification of a building material with the step of applying a layer of the building material on a building base within a build area and with the step of selectively solidifying the applied layer by solidifying an area of the applied layer which corresponds to the cross-section of the object in the layer in order to produce a solidified area in the layer. The steps of applying and selectively solidifying are repeated until the three-dimensional object is completed. At least once during manufacturing the three-dimensional object, a sub-area that is only a predetermined portion of the solidified area is after-treated. The sub-area is located substantially inside the solidified area.Type: ApplicationFiled: March 22, 2017Publication date: June 24, 2021Applicant: EOS GmbH Electro Optical SystemsInventors: Nikolai Zaepernick, Peter Keller, Florian Pfefferkorn, André Danzig, Andreas Pfister

Patent number: 10946446Abstract: A method for producing a three-dimensional object by applying layers of a pulverulent construction material and by selectively solidifying said material by the action of energy comprises the steps: a layer of the pulverulent construction material is applied to a support or to a layer of the construction material that has been previously applied and at least selectively solidified; an energy beam from an energy source sweeps over points on the applied layer corresponding to a cross-section of the object to be produced in order to selectively solidify the pulverulent construction material; and a gas flow is guided in a main flow direction (RG) over the applied layer during the sweep of the energy beam. The main flow direction (RG) of the gas flow (G) and the sweep direction (RL) of the energy beam are adapted to one another at least in one region of the cross-section to be solidified.Type: GrantFiled: May 28, 2019Date of Patent: March 16, 2021Assignee: EOS GmbH Electro Optical SystemsInventors: Robert Achim Domrose, Michael Hutzel, Alexander Schilling, Andre Danzig, Jorg Hamann, Thomas Hess, Marc Dimter
