Abstract：2024 aluminum alloy was formed by selective laser melting technology, the effect of scanning interval on microstructure and mechanical properties at room temperature was studied. The results show that when the scanning interval is 0.12 mm, the microstructure of 2024 aluminum alloy is more fine, the hardness is up to 124 HB, and the tensile strength is 372 MPa.
