3D printing, also known as additive manufacturing, is a transformative technology that creates three-dimensional objects by sequentially layering material based on digital models. This process involves the use of computer-aided design (CAD) software to generate precise specifications, which are then translated into physical forms using various materials, such as plastics, metals, and ceramics. The versatility of 3D printing enables rapid prototyping, customized production, and complex geometries that would be difficult or impossible to achieve with traditional manufacturing techniques. Its applications span multiple industries, including aerospace, healthcare, automotive, and consumer goods, revolutionizing the way products are designed, produced, and distributed.
