However, the traditional fiber composite material has a complex molding process, often requires a mold, and has a long manufacturing cycle, which greatly limits the further development and application of this type of composite material.

The emerging three-dimensional printing (3D printing) technology in recent years provides a new method for the integrated rapid prototyping of complex structures. However, the existing 3D printing molding process still has the problem of insufficient interlayer bonding strength, which in turn affects the overall mechanical properties of the structure. The use of 3D printing technology to build complex part geometry can avoid the defects of traditional manufacturing processes that require complex molds to be prepared in advance. Considering the defects of low mechanical properties of structural parts directly manufactured by existing 3D printing technology, supplemented by injection molding process to fill the internal space of complex geometric contours, it is an effective method to improve the mechanical properties of 3D printed structural parts.
