Abstract: 3D printing technology can overcome the geometric limitations of parts manufacturing through directional layering,which has attracted significant attention from academia and industry.However,this directional construction method has caused a series of problems such as the staircase effect,insufficient strength and supporting structure requirements of the parts.To solve the traditional layer printing problems,the multi-axis 3D printing technology was developed,which dynamically constructed parts with multi-degree-of-freedom robots to solve the limitations of traditional layered printing and illustrate the flexibility of robots to manufacture parts.The multi-axis 3D printing technology was reviewed.Some problems existing in traditional 3D printing were analyzed first,and then the research progress of multi-axis 3D printing technology was summarized,including the research status of multi-axis 3D printing technology to path planning,mechanical properties improvement of parts,non-supported printing,staircase effect elimination and realize large-scale printing realization.The current problems and the future development of multi-axis 3D printing technology were discussed.
