3D printing is usually achieved by using digital technology material printers. It is often used to make models in mold manufacturing, industrial design and other fields, and then gradually used in the direct manufacturing of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, and other fields.
Currently, 3D printing metal powder materials include cobalt-chromium alloys, stainless steel, industrial steel, bronze alloys, titanium alloys, and nickel-aluminum alloys. However, in addition to good plasticity, 3D printing metal powder must also meet the requirements of high powder purity, small particle size, narrow particle size distribution, high sphericity, low oxygen content, good fluidity and high bulk density.
