Metal additive manufacturing (AM), or metal 3D printing, is a process where digital 3D models are used to build metallic components by adding material layer-by-layer. This technology enables the creation of complex geometries—such as internal cooling features or lightweight lattices—that are impossible to produce with traditional subtractive methods like machining.

: Apply heat treatment, sintering, or surface finishing to achieve the required mechanical properties.

: The machine automatically constructs the part layer-by-layer, typically using a laser or electron beam to fuse material.

: Final inspection and qualification of the part for its intended use.
