Abstract: The nozzle blocking by melt and the low forming accuracy of products are two potential troubles for the fused deposition molding (FDM) technology. The optimization of a FDM nozzle system is beneficial to the reduction of the incidence of equipment failures and the improvement of the quality and printing efficiency of molding products. During the printing process, the working state of nozzle system is complex and variable. This paper reviews the research progress and development trends of the nozzle system both at home and abroad in recent years, which mainly included the flow channel structure of the nozzle system, cooling device and nozzle. Based on research and analysis, the nozzle system was found to become the core part of FDM equipment, and there were a number of great challenges in the current nozzle systems. However, with the continuous development of advanced technologies, the future nozzle systems can well face these challenges. The development of innovative technologies in nozzle systems may bring about a breakage in the limitations of FDM equipments, leading to the successful production of new products for the demands in industrial and civil applications.

Key words: fused deposition molding technology, nozzle system, challenge, development trend
