[0003] Most of the materials used in 3D printing technology are single materials, and the preparation method of composite filaments is not yet mature

Therefore, in order to meet higher usage requirements and overcome the shortcomings of insufficient comprehensive mechanical properties of existing 3D printing filaments, continuous fiber composite filament manufacturing equipment has emerged as the times require.

However, in the existing continuous fiber composite filament manufacturing equipment, the heating mechanism and the nozzle are often connected by a conveying pipe to convey the molten matrix. In order to realize the effective compounding of the molten matrix and the continuous fiber, the nozzle structure is relatively complicated. , due to the long path of the pipeline and heat loss, etc., it is often necessary to install a heating device at the position of the nozzle, which makes the design of the nozzle difficult and is not conducive to optimizing the overall structure of the equipment
