Closure device for 3d printing/coater device with control means
A recently granted patent (Publication Number: US11964434B2) discloses a closure device designed for use in a coater device within a 3D printing device. The closure device features a controllable closure means that can be opened by a control means, which includes an eccentric and/or a slotted link. This closure means is responsible for closing the coater device to prevent the outflow of particulate material and opening it to allow the material to flow. Additionally, the closure device includes a vertically adjustable orifice plate that controls the size of the discharge gap of the coater device, ensuring precise control over the material flow.
Furthermore, the patent details various specific aspects of the closure device, such as its application in a powder coater, the maximum opening width of the closure means, the speed at which the actuator opens the closure device, and the materials used in its construction. The closure device is also described as having a discharge opening at the end of the coater device, just before a construction space, emphasizing its crucial role in the 3D printing process. Overall, this patented closure device offers a unique and innovative solution for controlling the flow of particulate material in a coater device within a 3D printing setup, showcasing advancements in the field of additive manufacturing technology.
