Breathable steel is a kind of porous metal material, both metal materials and breathable materials two major properties, usually used in injection molds, in the appropriate position of the injection mold inlaid with breathable steel, by the injection molding problems formed by the trapped gas, can be completely removed, so that the molding process is more complete, can greatly reduce production costs, to bring greater economic benefits to enterprises.
At present, most of the ordinary breathable steel on the market is occupied by Japanese and American brands, and many factors such as its performance and quality seriously restrict the development of China's mold industry. Now, with the continuous development of 3D printing technology, 3D printing breathable steel is recognized by more and more enterprises, and the difference between 3D printing breathable steel and ordinary breathable steel is mainly in several aspects, manufacturing process, materials and properties.
First of all, in terms of manufacturing process, 3D printed breathable steel is manufactured using 3D printing technology, which can create more complex internal structures and molds with arbitrary geometries, while traditional breathable steel is usually manufactured by machining or casting.
Secondly, in terms of materials, 3D printing breathable steel can be printed with various metal powders, plastics and other materials to meet application requirements, while ordinary breathable steel is a special powder metallurgy porous material, which is composed of countless tiny pores.
In terms of performance, both 3D printed breathable steel and ordinary breathable steel have breathable properties, but 3D printed breathable steel can adjust the material and process parameters during the manufacturing process to control its porosity, strength and other properties, so as to better meet the needs of practical applications.
In addition, 3D printing breathable steel has higher customizability, and can be personalized according to customer needs, not limited by location and shape, to create breathable steel that is more in line with the needs of practical applications, and the characteristics of conformal breathable steel are not available in ordinary breathable steel. At the same time, the 3D printing process can greatly shorten the product manufacturing cycle, reduce material waste, and reduce production costs.
In general, 3D printing breathable steel has the advantages that ordinary breathable steel does not have in many aspects, such as manufacturing flexibility and use effect, and with the continuous development of 3D printing technology, 3D printing conformal breathable steel will gradually become the mainstream.
