Problems solved by technology

Nozzle clogging due to fiber accumulation is a common problem in the 3D printing process of composite materials. At present, the composite materials used in 3D printing are mainly divided into short fiber reinforced composite materials (fiber length is smaller than the nozzle diameter) and continuous fiber reinforced composite materials. However, there is no relevant report on the 3D printing technology of composite materials with variable fiber length.
In addition, magnetic fiber reinforced composite materials have broad application prospects in the field of electromagnetic shielding. Using 3D printing technology to process and manufacture complex electromagnetic shielding structural parts can effectively avoid the problem of difficult processing in local areas, but magnetic fiber reinforced composite materials in 3D Nozzle clogging due to inconsistent magnetic fiber orientation during printing

Abstract

The invention discloses a device for controlling the magnetic field direction of a 3D printing composite fiber material, a magnetic field generating device is arranged on the peripheral side of a printing material melting area of a 3D printing system, and the size and the direction of a magnetic field generated by the magnetic field generating device can be adjusted. The invention further discloses a 3D printing system comprising the device and a 3D printing method. The invention relates to a 3D printing technology for controlling orientation of magnetic fibers through magnetic field orientation and a corresponding novel magnetic assembly 3D printing process. In the printing process, an external magnetic field is applied to induce the magnetic fibers mixed in the base material to be arranged in order, the space orientation of the fibers is controlled by planning the direction of the magnetic field, the length and orientation of the magnetic fibers are controlled, then parts of an ordered fiber structure are prepared, the specific function requirements of the parts are met, and the manufacturing cost is reduced. Therefore, the purpose of light weight of parts is achieved.
