Metal 3D printing is a manufacturing process that creates three-dimensional objects from metal materials. It involves layering fine metal powders and using techniques like laser sintering or electron beam melting to fuse the particles together. This technology allows for complex designs that are often difficult or impossible to achieve with traditional methods. The advantages of metal 3D printing include reduced waste, faster production times, and the ability to customize parts for specific applications. Industries such as aerospace, automotive, and medical are increasingly adopting this technology to produce lightweight, strong components that meet precise specifications.
