Additive manufacturing, often known as 3D printing, is a process that creates objects layer by layer from a digital design. Unlike traditional manufacturing, which often involves cutting away material, additive manufacturing builds items by adding material, such as plastic or metal, in precise shapes. This method allows for complex designs that would be difficult or impossible to achieve with conventional techniques. One of the key benefits of additive manufacturing is its ability to reduce waste, as it only uses the material needed for the final product. Additionally, it enables rapid prototyping, allowing designers and engineers to quickly test and modify their ideas. This technology is transforming industries like aerospace, automotive, and healthcare by making production more efficient and customizable.
