Additive processes refer to methods of creating objects or structures by adding material layer by layer. This approach is commonly used in fields like manufacturing and 3D printing, where digital designs are transformed into physical items. By building up materials, these processes allow for complex shapes and designs that traditional subtractive methods may not easily achieve.
In contrast to subtractive processes, which involve cutting away material from a solid block, additive processes focus on accumulation. Techniques such as fused deposition modeling and stereolithography exemplify this method, enabling the production of prototypes, custom parts, and even intricate art pieces.
