Patent number: 11325188Abstract: This invention concerns an additive manufacturing apparatus for building objects by layerwise consolidation of material. The apparatus includes a build chamber containing a working area, a high energy beam for consolidating material deposited in the working area in layers and a flow device for generating a gas flow across at least a part of the working area from a gas inlet to a gas outlet. The gas inlet and gas outlet are arranged to be movable within the build chamber.Type: GrantFiled: February 26, 2019Date of Patent: May 10, 2022Assignee: RENISHAW PLCInventors: David Roberts McMurtry, Marc Dimter, Ralph Mayer

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

Publication number: 20160175932Abstract: An additive manufacturing method including building an object layer-by-layer by, repeatedly, providing a layer of material on build platform and scanning a beam across the layer to consolidate material. A plurality of supports may be provided for supporting object during build. Each support may include main body attached to the object by 2-dimensional pattern of frangible structures. The method may further include applying input force to main body to displace main body to break the frangible structures. Also relates to a support structure that may be used in this method. The support structure may include plurality of supports for supporting the object, each support including main body attached to object by a 2-dimensional pattern of frangible structures. The supports may be arranged such that main bodies define a gap therebetween into which at least one of main bodies can be displaced by an input force to break the frangible structures.Type: ApplicationFiled: August 4, 2014Publication date: June 23, 2016Applicant: RENISHAW PLCInventors: Marc DIMTER, Ralph MAYER
