Technical Field
The invention relates to the technical field of metal powder, in particular to aluminum alloy powder for additive manufacturing.
Background
With the continuous improvement of industrialization, additive manufacturing is widely applied in the fields of machining, die manufacturing and the like. At present, the rapid forming method for directly forming metal parts mainly comprises three methods: selective Laser Sintering (SLS), Laser Cladding (LC), Selective Laser Melting (SLM). The selective laser melting is an incremental manufacturing technology based on a discrete-accumulation concept, and contrary to the traditional material removing processing method, the selective laser melting is used for selectively melting metal powder layer by layer to accumulate and form metal parts, so that the selective laser melting has the obvious advantages of short production period, complex part geometric shape, various material processing types and the like
