Abstract: A real-time multi-parameter coordinating 3D printing auxiliary forming process for continuous fiber reinforced composites belongs to the technical field of 3D printing. The method starts an external auxiliary heating mechanism and an external auxiliary pressure mechanism timely according to the characteristics of forming materials, the structure of a forming component and interlayer pressure and temperature differences measured in real time during printing, increases interlayer forming pressure of 3D printing and reduces an interlayer temperature difference to improve interlayer bonding strength of the composites. Meanwhile, the method starts a dedicated auxiliary mechanism accompanying mechanism timely according to an established printing trajectory to ensure that the relative positions of an auxiliary mechanism and a printing device are kept unchanged in real time, to realize sustainable forming of multi-parameter coordinating 3D printing for continuous fiber reinforced composites. The method improves the interlayer bonding quality of the component.
