  • Sintering particulate material
    Patent number: 10471657
    Abstract: Disclosed are methods and apparatus for selectively sintering particulate material, the method comprising: providing a layer (6) of particulate material; providing an amount of a radiation absorbent material over a selected surface portion of the layer (6) of particulate material; providing an amount of a material that comprises a plurality of elongate elements (16) over at least part of the selected surface portion of the layer (6) of particulate material; and providing radiation (8) across the selected surface portion of the layer (6) of particulate material so as to sinter a portion of the material of the layer (6) including causing the plurality of elongate elements (16) to become embedded in the sintered portion of material.
    Type: Grant
    Filed: March 11, 2015
    Date of Patent: November 12, 2019
    Assignee: BAE Systems plc
    Inventors: Mark Alfred Potter, Matthew Nicholas Stevens
  • Forming a three dimensional object
    Patent number: 10293593
    Abstract: Disclosed are methods and apparatus for selectively sintering particulate material, the method comprising: providing a layer (6) of particulate material; providing an amount of a radiation absorbent material over a selected surface portion of the layer (6) of particulate material; providing an amount of a material that comprises a plurality of electrically conductive elements (20) over at least part of the selected surface portion of the layer (6) of particulate material; and providing radiation (8) across the selected surface portion of the layer of particulate material so as to sinter a portion of the material of the layer (6) including causing the plurality of electrically conductive elements (20) to become embedded in the sintered portion of material.
