  • Reflector and light sintering apparatus comprising the same
    Patent number: 12022579
    Abstract: Provided is a reflector comprising: an outer wall; and an inner wall which reflects the xenon lamp light from a xenon lamp toward an object to be light sintered, and which consists of inner side walls and an inner top wall which are spaced apart by a predetermined distance from the outer wall to allow cooling water for cooling heat generated by the xenon lamp light to flow, wherein at least a part of the inner side walls has the same thickness as at least a part of the inner top wall.
    Type: Grant
    Filed: September 18, 2020
    Date of Patent: June 25, 2024
    Assignee: IUCF-HYU (INDUSTRY-UNIVERSITY COOPERATION FOUNDATION HANYANG UNIVERSITY)

  • Device for light sintering and cooling method for device for light sintering
    Patent number: 11729942
    Abstract: A light sintering device is provided. The light sintering device can comprise: a housing having, therein, a cooling hollow portion in which cooling water flows; a beam guide mounted on one side of the housing so as to form one wall of the cooling hollow portion, and guiding sintered light; and an optical filter mounted on the other side of the housing so as to face the beam guide, thereby forming the other wall of the cooling hollow portion, and filtering out a specific wavelength of the sintered light.
