WAAM (Wire Arc Additive Manufacturing)

WAAM (Wire Arc Additive Manufacturing) е DED (Directed Energy Deposition) вариант, при който welding wire feed + electric arc или plasma source топи материала и го депонира слой по слой. Не powder bed: wire feedstock на robot arm или gantry. ISO/ASTM 52900 → DED.

WAAM е най-бързият metal AM процес: kg-per-hour throughput (vs gram-per-hour DMLS). Идеален за large parts (>1 m), low-cost wire material (welding wire €20/kg vs powder €100/kg). Trade-off: surface е rough, нужно CNC post-machining.
