3D Printing Molding Technology and Optimization Design of Process Parameters

In recent years, the layer-by-layer stacking principle of 3D printing technology makes it more flexible, which has attracted more and more attention and become a new research hotspot.Starting from the forming quality, this paper discussed the optimal process parameters of the fused deposition modeling 3D printing technology, with emphasis on the process principle and process flow of the equipment, the effects of printing temperature, printing speed, printing layer height, filling angle and filling density on the forming quality were summarized, the optimal conditions of 3D printing process parameters was obtained. The oxygen bottle model design is taken as an example to show that the application requirements of different parts can be improved by 3D printing parameters.
