Answer:
Additive manufacturing, also known as 3D printing, is a manufacturing process in which a digital model is used to create a physical object by adding successive layers of material. The process begins with a digital model created using computer-aided design (CAD) software or a 3D scanner. This model is then used to create a physical object by depositing or solidifying successive layers of material, such as plastic, metal, or ceramic, according to the design.
