Continuous fiber path generation method for multi-nozzle 3D printing and storage medium

Abstract

The invention discloses a continuous fiber path generation method for multi-nozzle 3D printing and a storage medium, and relates to the technical field of 3D printing. The method comprises the following specific steps: checking the integrity of a model file, and determining the minimum size information of a model; 3D printing path planning is carried out based on the minimum size information of the model; and performing path filling according to the path planning. According to the continuous fiber 3D printing process characteristics, the continuous fiber path generation method and the filling strategy of the 3D printing continuous fiber / resin composite material are provided by considering that the continuous fiber wire material printing path needs to be cut off, and the continuous fiber path generation method and the filling strategy are verified through a 3D printing experiment. The rapid forming method is provided for preparation of the continuous fiber / resin composite material component, controllable adding of continuous fibers can be achieved by freely designing the fiber laying path, the rapid forming method has great advantages especially for personalized customization of some composite material structures in complex geometrical shapes, and the printing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, and more specifically relates to a continuous fiber path generation method and storage medium for multi-nozzle 3D printing. Background technique [0002] With the continuous development of technology, only adding short fibers can no longer meet the needs of industrial production. Scholars at home and abroad have begun to turn their attention to continuous fibers, in order to obtain better material properties by adding continuous fibers to the resin matrix. The currently commonly used processing methods of fiber / resin composite materials such as: injection molding, hot pressing molding, compression molding, etc. Forming 3D printing technology has great advantages in the production of high-strength, light-weight, and complex-shaped fiber / resin composite materials. [0003] There are two main forms of continuous fiber / resin composite material equipment based on fused deposition modeling 3D prin...

AI Technical Summary

Problems solved by technology

Single-nozzle fiber dry filament 3D printing often has poor fiber-resin prepreg effect and poor mechanical properties of composite materials; while multi-nozzle pre-impregnated continuous fiber 3D printing composites have excellent mechanical properties, and the fiber filling method is better than single-nozzle 3D printing. There are more options, but there is currently less research on continuous fiber path generation methods for continuous fiber / resin composite 3D printing, and no slicing software based on continuous fiber / resin composite dual-nozzle 3D printing process is available
