Embodiment Construction
[0022] Selective Laser Melting (SLM) is considered to be one of the most potential metal additive manufacturing technologies. SLM technology mainly uses high-power or high-brightness laser as a heat source to melt metal powder layer by layer to directly manufacture parts with complex shapes. SLM technology uses a laser beam with a finely focused spot as the forming energy source, a high-speed and high-precision scanning galvanometer as the processing beam control unit, and adopts thinner layer thickness control technology. SLM technology has more advantages in obtaining high-density and high-precision formed parts. , can complete the direct forming of complex cavity, profile, thin wall and variable cross-section parts, such as aero-engine pre-swirl nozzles, fuel nozzles, turbine blades and other parts.
[0023] In view of the problem that the local performance of a single part cannot be customized in the existing part manufacturing process, the following embodiments provide a ...
