Design Optimization of Flange Parts Based on 3D Printing Simulation

In this paper, we simulate the 3D printing process of flange parts based on Unigraphics software, through the setting of printing speed, nozzle temperature, printing layer thickness, printing material and other related parameters, we simulate the high temperature area and deformation area in the Fused Deposition Modeling printing process, and compensate and optimize the model to obtain a better new 3D printing model, and then compare the simulation results of two models and the actual printing results respectively. Finally, the simulation results of the two models and the actual printing results are compared and conclusions are drawn. The simulation results of the temperature field of the part show that the optimized model effectively reduces the area of the internal and external high-temperature region, in which the maximum temperature of the top surface of the hexagonal prism of the flange part is reduced by about 150 ℃ and the minimum temperature is reduced by about 300 ℃, the simulation results of the deformation of the part show that the maximum deformation of the printed part is reduced from 0.1179 to 0.0814 mm when the part is not cooled, and the deformation is reduced from 0.302 mm after the cooling support is removed. After the cooling support was removed, the deformation was reduced from 0.302 to 0.228 mm, and the temperature and deformation were obviously optimized. Finally, through the actual 3D printing of the two models, the results show that the unoptimized initial part has obvious paste and deformation at the top after printing, while the optimized part has no such situation. From the above analysis, it is concluded that the compensation optimization function of Unigraphics software has an important role in reducing the temperature and deformation during the 3D printing of the parts.
