Problems solved by technology

Since there is no special magnetic material for 3D printing, the magnetic properties of magnets prepared by different research institutions are quite different.
Moreover, there is a lack of special magnetic material printing equipment. At present, the method of printing first and then magnetizing is used. The advantages of 3D printing complex magnetic circuit devices have not been fully utilized, and there is still a certain gap from practical applications.

Abstract

The invention relates to a magnetic material 3D printing device. Specifically, on the basis of traditional fused deposition modeling equipment (FDM), the equipment uses a screw extrusion structure instead of a traditional gear wire feeding mechanism and a magnetization device is provided at the lower end of the screw extrusion structure, which can realize magnetic materials Great improvement in molding efficiency and magnetic properties.

Description

technical field [0001] The invention relates to the field of material processing, in particular to a magnetic material 3D printing device. Background technique [0002] Additive manufacturing technology (also known as "3D printing") is a method of directly manufacturing three-dimensional physical entities in a layer-by-layer manner based on a computer-based three-dimensional CAD model. Additive manufacturing technology can quickly and precisely manufacture parts of any complex shape and structure on one piece of equipment, thus realizing "free manufacturing". Compared with traditional processing technology, additive manufacturing can reduce processing costs by more than 20%-40%, and shorten product development cycle by about 80%. [0003] In the past 20 years, additive manufacturing technology has developed rapidly, and a variety of molding technologies and equipment have been formed. These technologies are aimed at high-end manufacturing fields such as aerospace, weaponry...
