  • Additive manufacturing apparatus and methods
    Patent number: 11780161
    Abstract: An additive manufacturing apparatus including a scanner for directing a laser beam on to layers of flowable material to selectively solidify the material to form an object in a layer-by-layer manner. The scanner includes an optical component operable under the control of a first actuator to reflect the laser beam over a first range of angles in a first dimension and the or a further optical component operable under the control of a second actuator to reflect the laser beam over a second range of angles in the first dimension, wherein the second actuator provides a faster dynamic response but a smaller range of movement of the laser beam than the first actuator.
    Type: Grant
    Filed: August 11, 2022
    Date of Patent: October 10, 2023
    Assignee: RENISHAW PLC
    Inventors: Ceri Brown, Nicholas H H Jones, David G J Ewing, Geoffrey McFarland
