A recently granted patent (Publication Number: US11878350B2) discloses a three-dimensional (3D) print engine designed for fabricating 3D articles. The print engine includes a build chamber with walls, a build box with a build plate connected to a vertical positioning system, a powder dispenser, and a beam system that generates energy beams for powder fusion. A gas handling system with inlet and outlet streams, along with projecting structures on a peripheral plate, shapes the gas flow stream to ensure uniform velocity above the build plane. The controller coordinates the operation of various components to fabricate the 3D article layer by layer, showcasing an innovative approach to additive manufacturing technology.

Furthermore, the patent details specific configurations and features of the 3D print engine, such as the size of the build plate, the design of the peripheral plate, and the arrangement of the projecting structures. The method outlined in the patent involves precise steps, including positioning the build plate, dispensing powder, emitting and shaping the gas flow stream, and fusing the powder layers using the energy beams. By emphasizing the importance of uniform gas flow velocities and controlled powder fusion, the patent highlights the technical advancements in 3D printing technology. Overall, the patent provides a comprehensive overview of a sophisticated 3D print engine and a method for fabricating high-quality 3D articles with efficiency and precision.
