Additive Manufacturing: Process and Industrial Significance
Additive manufacturing, often referred to as 3D printing, is a production method that creates objects by layering materials according to digital designs. Unlike subtractive techniques, which remove material from a solid block, additive manufacturing builds components sequentially, allowing precise control over geometry and material distribution.
Process OverviewThe process begins with a digital 3D model, which is divided into thin cross-sectional layers by computer software. Each layer is then deposited using methods such as material extrusion, powder bed fusion, binder jetting, or stereolithography. The material—commonly polymers, metals, or ceramics—is either melted, cured, or fused to form the final solid structure.
ApplicationsAdditive manufacturing is used in engineering, healthcare, aerospace, construction, and research. It enables the fabrication of prototypes, functional components, and complex geometries that may be difficult to achieve with traditional techniques. The technology is also utilized in producing customized medical implants, lightweight structural parts, and precision tools.
