3D printing has revolutionized the manufacturing process and is transforming the world, which transform the design ideas quickly into real, especially ones with complex structure which is complicate to produce. At this stage, there are two factors to limit the development of 3D printing technology——printing materials and equipment. Currently the main 3D printing material include engineering plastics, photosensitive resin, rubber materials, photosensitive materials, ceramic materials and metallic material and in the form of powder, filamentous, lamellar and liquid-like.
