  • Additive manufacturing temperature controller/sensor apparatus and method of use thereof
    Patent number: 10603742
    Abstract: An additive manufacturing temperature controller/temperature sensor uses one or more spectrophotometric sensors to monitor temperature of successive layers and preferably localized sections of successive layers of a melt pool, and transients thereof, of an object being generated for the purpose of dynamic control of the additive manufacturing device and/or quality control of the generated object manufactured with the additive manufacturing device. Generally, the additive manufacturing temperature controller/sensor apparatus monitors temperature of a section of the object during manufacture as a function of wavelength, time, position, and/or angle to determine melt extent in terms of radius and/or depth.
    Type: Grant
    Filed: February 10, 2017
    Date of Patent: March 31, 2020
    Inventor: James Eldon Craig
