Additive Manufacturing

The construction of complex three-dimensional parts from 3D digital model data by depositing successive layers of material. Metal, polymer, and ceramic materials can be used to manufacture parts of a geometry that often cannot be produced by any other manufacturing technology. The names of specific additive manufacturing technologies include: 3D printing, layered object manufacturing, selective laser sintering, selective laser melting, LENS, stereolithography, and fused deposition modeling. Synonyms include layered manufacturing, solid freeform manufacturing, direct digital manufacturing, rapid prototyping.1
