Review on Optimization of Process Parameters of FDM 3D Printing Technology

In recent years, with the gradual maturity of 3D printing technology, there has been an increasing amount of research on printing-related technologies. The fused deposition modeling technology is simple to operate and control, reliable in printing, and has low costs. It has gradually become a key technology in 3D printing. Among the numerous research contents, more attention has been paid to the forming process parameters, forming quality, and forming mechanical properties. This paper summarizes the latest progress in FDM forming process optimization methods, the influence of process parameters on part quality, finite element simulation analysis, and experimental optimization design. It points out the research progress and deficiencies in each direction and proposes a future development direction of improving FDM part quality through process parameter optimization.
