Patent number: 11426944Abstract: Disclosed is a method for supervision of an additive manufacturing process for producing a manufacturing product by selectively solidifying build-up material in a process chamber. The build-up material is irradiated according to predefinable irradiation control data; and a process chamber supervisory data set is generated based on the irradiation control data, supervisory data being encoded process chamber point by process chamber point in said data set. Quality data concerning the manufacturing process are determined based on the process chamber supervisory data set. A description is further given of a supervisory device suitable therefor a control device for an apparatus for additive manufacturing of manufacturing products, and an apparatus for additive manufacturing of manufacturing products comprising such a control device.Type: GrantFiled: April 12, 2018Date of Patent: August 30, 2022Assignee: EOS GmbH Electro Optical SystemsInventors: Markus Frohnmaier, Marcus Schmidt, Harald Krauss, Michael Sirch

Patent number: 11207837Abstract: A method for providing control commands for producing a number of three-dimensional objects by an additive layer-wise building device. The method can include a step of providing a computer-based model of the number of objects that geometrically describes the objects, a step of modifying the computer-based model such that for the geometric description of the number of objects a location is defined as a common origin of coordinates, and a step of generating control commands for a set of control commands for controlling the production of the number of objects by the additive layer-wise building device on the basis of the modified computer-based model.Type: GrantFiled: April 15, 2016Date of Patent: December 28, 2021Assignee: EOS GmbH Electro Optical SystemsInventors: Ludger Hümmeler, Manfred Semmler, Siegfried Mayer, Markus Frohnmaier

Patent number: 10414095Abstract: An exposure control device serves for equipping and/or retrofitting a generative layer-wise building device. The exposure control device has a first data output interface, at which control commands can be output to the exposure device. The control commands specify one of a plurality of exposure types defined by a predetermined combination of a radiation energy density to be emitted by the exposure device and a scanning pattern with which the radiation is being directed to a region of a layer of the building material. The exposure control device also includes a second data output interface at which an exposure type can be output in real time in relation to a timing of the output of a control command specifying this exposure type.Type: GrantFiled: June 20, 2017Date of Patent: September 17, 2019Assignee: EOS GmbH Electro Optical SystemsInventors: Markus Frohnmaier, Michael Göth, Robert Achim Domröse, Stefan Fröbe, Joachim Wichner, Harald Häger

Publication number: 20180001563Abstract: An exposure control device (31) serves for equipping and/or retrofitting a generative layer-wise building device (1). The latter comprises an exposure device (20) which emits electromagnetic radiation (22) or particle radiation and is configured to irradiate positions to be solidified in a layer in such a way that after cooling they exist as an object cross-section or part of the same. The exposure control device (31) has a first data output interface (36), at which control commands can be output to the exposure device (20). The control commands which are output specify one of a plurality of exposure types wherein an exposure type is defined by a predetermined combination of a radiation energy density to be emitted by the exposure device (20) and a scanning pattern with which the radiation (22) is being directed to a region of a layer of the building material (15).Type: ApplicationFiled: June 20, 2017Publication date: January 4, 2018Applicant: EOS GmbH Electro Optical SystemsInventors: Markus Frohnmaier, Michael Göth, Robert Achim Domröse, Stefan Fröbe, Joachim Wichner, Harald Häger

Patent number: 8260447Abstract: In a method of providing a material amount for a generative manufacturing method, a three-dimensional object (2) is formed by selectively solidifying layers of a material at locations corresponding to the cross-section of the object (2) in the respective layers. The quality of the manufactured objects is reproducibly recorded, thus, improving the method. At least one first material amount of a powder is provided, which is characterized by at least one feature. Data is detected, which relates to the at least one feature of the first material. Then, the data is stored, which relates to the at least one feature of the first material. Thus, the method can provide an identifiable powder amount used in manufacturing each layer of the object.Type: GrantFiled: December 1, 2009Date of Patent: September 4, 2012Assignee: EOS GmbH Electro Optical SystemsInventors: Thomas Mattes, Ludger Hümmeler, Markus Frohnmaier
