  • Patent number: 11679552
    Abstract: A direct ink writing device and method for a bias-controllable continuous fiber reinforced composite material are provided. The device includes a cartridge fixed by an external device, a bottom of the cartridge is connected to a nozzle. A piston is arranged in the cartridge, the piston is provided with a chamber for containing sealing liquid and a capillary for a continuous fiber to pass through. The centers of an inner circumference and an outer circumference of the cartridge do not coincide with each other. The bias position of the continuous fiber in the composite material is achieved using the piston, and each filament of composite material is printed in steps of rotation, extrusion, revolution and curing. A structure produced according to the disclosure has high mechanical properties and outstanding intelligent properties, and the bias position of the continuous fiber material in the structure can be accurately adjusted.
