摘要：

This study describes a 3D fused deposition modeling (FDM) printing process using a graphene-impregnated polylactic acid (G-PLA) filament to create a new type of rigid, plastic, nonconductive, and anticorrosion layer. Therefore, the possibility of 3D printing a plastic layer using FDM methods is demonstrated herein. A commercial magnet such as N35 NdFeB can be used to produce an efficient shielding film by additive manufacturing. As the coating layer thickness increases, the remanence decreases from 1.17 to 1.01 T for the G-PLA coating. Visual tests were performed after exposure to all aqueous NaCl test solutions (0.5 and 1M), and no evidence of corrosion of the coating was obtained.
