Additive manufacturing

Definition

Additive manufacturing is a process that creates three-dimensional objects by layering materials, typically plastics, metals, or ceramics, based on digital models. This innovative technique differs from traditional subtractive manufacturing by building products layer by layer, which allows for more complex designs and reduces material waste. It plays a crucial role in creating sustainable products, promoting efficiency in production, and enabling rapid prototyping in green product development.
