MUMBAI, India, July 25 -- Intellectual Property India has published a patent application (202537062675 A) filed by Nobula3D AB, Stockholm, on July 1, for 'apparatus for additive manufacturing.'
Inventor(s) include Fokine, Michael; Liu, Chunxin; and Oriekhov, Taras.
The application for the patent was published on July 25, under issue no. 30/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to an apparatus (100) for additive manufacturing of a three- dimensional glass object. The apparatus comprises a stage (130) for supporting the glass object, a laser beam source (110) for providing a primary laser beam (150), a printer head (102), and means for relative movement of the printer head (102) and the stage (130), wherein the printer head (102) comprises at least one glass filament feeding nozzle (120) for feeding a glass filament (160) towards a location of deposit (140) in order to form the glass object, and an optical beam path unit configured for directing the laser beam (150) from the laser beam source (110) to the location of deposit (140) for heating the glass filament (160). The apparatus is characterized in that the optical beam path unit comprises a beam splitter (145) in order to divide the primary laser beam (150) into at least three partial laser beams (150'), wherein the optical beam path unit is configured for directing each of the at least three partial laser beams (150') from the beam splitter (145) to the location of deposit (140), and a feed-back control unit comprising means for monitoring a process parameter that is representative for the temperature at the location of deposit (140) and means for controlling the power of the primary laser beam (150) in order to adjust the temperature at the location of deposit (140) towards a predetermined level."
The patent application was internationally filed on Jan. 11, 2023, under International application No.PCT/SE2023/050027.
