Additive manufacturing

Definition

Additive manufacturing, commonly known as 3D printing, is a process that creates objects by adding material layer by layer based on digital models. This technology allows for greater design flexibility and customization, enabling the production of complex shapes that traditional manufacturing methods cannot achieve. It has significant implications for industries like aerospace, healthcare, and consumer goods, shaping the future of production and labor.

5 Must Know Facts For Your Next Test
