In order to obtain the ideal parameters about influence degree of melting supplies and the ideal cooling structure of throat, and provide empirical datum for further research, this paper has used finite element method (FEM) to analyze a new type of FDM nozzle structure to study the effect of temperature on the nozzle head of different degree of melting of PLA supplies, the impact of different cooling air flow at the degree of melting of the PLA supplies, and the effects of differently cooling structure of the degree of melting of PLA supplies. The simulation results show that the heat dissipating structure with 195℃, nozzle temperature, 180 W/(m^2·℃) forced convection coefficient and Ф25mm heat pipe diameter of circumstances has good forming effect. In other words, the structure not only has an excellent performance in the throat but also could provide stable and reliable technical support for FDM prototyping equipment.
