On July 8, 2024, the Wuhan National Laboratory for Optoelectronics at Huazhong University of Science and Technology, together with the Shanghai Aerospace Precision Machinery Research Institute and the Singapore Centre for 3D Printing at Nanyang Technological University, published an academic paper online on residual deformation in lattice structures formed by laser powder bed fusion (LPBF). The study focused on three basic lattice structures, body-centered cubic (BCC), face-centered cubic (FCC), and diamond (DC), and systematically analyzed the residual deformation behavior and mechanisms during LPBF forming. The research examined deformation from three dimensions: horizontal direction, build direction, and total deformation, revealing differences in deformation modes of lattice structures at different relative densities. Low-relative-density samples were dominated by the structural deformation mode (SDM), producing larger deformation, while high-relative-density samples shifted to an intrinsic deformation mode (IDM) dominated by shrinkage during the forming process. Among them, the FCC structure showed the best stability and the smallest residual deformation at most densities. The paper detailed process and material parameters such as laser power, scan spacing, spot radius, thermal conductivity, and coefficient of thermal expansion, and provided a calculation framework for mechanical performance indicators such as elastic modulus and yield strength. The study directly addresses the residual deformation problem of lattice structures in the LPBF process, and LPBF is one of the core process routes in metal additive manufacturing that uses metal powder as raw material. The paper's conclusions can provide a unified deformation prediction basis for the design process of lattice structures with different configurations, helping to improve the dimensional accuracy and process reliability of metal powder bed fusion formed parts.
