In this paper, epoxy acrylate/nickel-plated carbon nanotubes composites with different structural orientations (X, Z) were prepared by digital light procession 3D, and the orientation of nickel-plated carbon nanotubes in the magnetic field and its effect on the mechanical properties of the composites were systematically studied. The scanning electron microscope shows the orientation of the fiber in the magnetic field. The experimental results show that the mechanical properties and friction coefficient of the material show obvious anisotropy, but the anisotropy of wear rate is not obvious. The tensile strength of the X sample is about 18% higher than that of the Z sample when the content of nickel-plated carbon nanotubes was 0.15 wt%. The impact strength of the X sample is about 15% higher than that of the Z sample when the content of Ni-MWNTs was 0.1 wt%. The friction coefficient on the plane (X, Y) is about 20% lower than that on the plane (Y, Z) when the content of carbon nanotubes is 0.05 wt%.
