Recently, metal 3D printing technology has made significant progress in material performance, printing efficiency, and application expansion. Researchers have substantially improved the density and mechanical properties of printed components—bringing them on par with or even surpassing those produced by conventional manufacturing methods—by optimizing laser melting parameters and developing novel alloy powders. Meanwhile, the widespread adoption of multi-laser cooperative printing systems has greatly enhanced production efficiency and shortened lead times for large, complex parts. Moreover, the technology is rapidly penetrating high-end manufacturing sectors such as aerospace, medical devices, and energy equipment. For instance, metal 3D printing is already being used in small-batch production of aircraft engine turbine blades and customized orthopedic implants, demonstrating advantages like high design freedom and superior material utilization. Experts note that as costs continue to decline and standardization frameworks mature, metal 3D printing is poised to achieve large-scale industrial adoption within the next five years, becoming a cornerstone of smart manufacturing.
