A Review of FDM Nozzle System for Additional Materials Manufacturing Technology

Compared with the traditional material reduction manufacturing, additive manufacturing technology is a great change, which brings new opportunities for the production models. Fused Deposition Molding (FDM) equipment is one of the most widely used to additive manufacturing equipment. The nozzle system is the core component of FDM technology. Its performance directly affects the product forming accuracy and efficiency. Therefore, taking FDM nozzle system as the research object, this paper reviews the research process and development trends of the nozzle system at home and abroad in recent years from the aspects of its flow channel structure, heat sink, heating device and nozzle, points out the hotspots and challenges of nozzle system research, which provides important reference for the optimization design of nozzle system.
