Abstract
A lower surface of the printing platform is provided with a displacement device, and the displacement device is used to rotate the printing platform horizontally and adjust a pitch angle of the printing platform. The additive device is located above the printing platform and is connected to one end of the robotic arm, and the additive device is provided with a pressing roller. The robotic arm includes rotating joints used to drive the additive device to print and melt a fiber tow on the printing platform according to a predetermined path. The fiber pulling device is disposed on the printing platform to grab the reinforced fiber and make it cross-weave with the horizontally printed fiber tow on the horizontal plane. When working, the pressing roller is always perpendicular to the printing platform to press the melted fiber tow and the reinforced fiber cross-woven with the fiber tow.
