Title: Guofeng Han: Innovator in 3D Printing Technology
Introduction
Guofeng Han is a prominent inventor based in Beijing, China. He has made significant contributions to the field of 3D printing technology, particularly in the preparation of spherical metal powders. With a total of 4 patents to his name, Han's work is paving the way for advancements in additive manufacturing.
Latest Patents
One of Han's latest patents is titled "Device and method for high-efficiency preparation of spherical metal powder for 3D printing employing separation into fibers." This innovative apparatus includes a housing, a crucible, and a powder collection area, featuring a turnplate designed as an inlaid structure. The turnplate is made from a material with poor thermal conductivity, and it incorporates a metal material with a wetting angle of less than 90° to serve as the atomization plane. This design allows for the combination of electromagnetic force and centrifugal atomization, breaking through traditional metal split modes and enabling fibrous splitting of molten metal.
Another notable patent is "Apparatus and method for preparing spherical metal powder based on one-by-one atomization method for uniform droplets." This apparatus also consists of a housing, a crucible, and a collection bin, with a turnplate featuring a concentric circular groove. By combining the pulsated orifice ejection method with centrifugal atomization, this invention achieves a fibrous split mode, allowing for the production of high-melting-point metal powders with controllable particle sizes, high sphericity, and excellent flowability.
